Details regarding the choice of hydraulic fluid

The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in an open circuit, the reservoir temperature.

The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range (νopt see shaded area of the selection diagram). We recommended that the higher viscosity class be selected in each case.

Example: At an ambient temperature of X °F (X °C), an opera-ting temperature of 140 °F (60 °C) is set in the circuit. In the optimum operating viscosity range (νopt., shaded area), this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68.

NoteThe case drain temperature, which is affected by pressure and speed, can be higher than the reservoir temperature. At no point of the component may the temperature be higher than 240 °F (115 °C). The temperature difference specified below is to be taken into account when determining the viscosity in the bearing.

If the above conditions cannot be maintained due to extreme operating parameters, we recommend flushing the case at port U (size 250).

Filtration of the hydraulic fluidFiner filtration improves the cleanliness level of the hydraulic fluid, which increases the service life of the axial piston unit.

To ensure the functional reliability of the axial piston unit, a gravimetric analysis of the hydraulic fluid is necessary to de-termine the amount of solid contaminant and to determine the cleanliness level according to ISO 4406. A cleanliness level of at least 20/18/15 is to be maintained.

At very high hydraulic fluid temperatures (+195 °F to +240 °F (90 °C to maximum 115 °C)), a cleanliness level of at least 19/17/14 according to ISO 4406 is necessary.

If the above classes cannot be achieved, please contact us.

Shaft seal

Permissible pressure loading

The service life of the shaft seal is influenced by the speed of the axial piston unit and the case drain pressure (case pressu-re). The mean differential pressure of 30 psi (2 bar) between the case and the ambient pressure may not be enduringly exceeded at normal operating temperature. For a higher differential pressure at reduced speed, see diagram. Momen-tary pressure spikes (t < 0.1 s) of up to 145 psi (10 bar) are permitted. The service life of the shaft seal decreases with an increase in the frequency of pressure spikes.

The case pressure must be equal to or higher than the ambient pressure.

Before finalizing your design, request a binding instal-lation drawing. Dimensions in inch and (millimeters).Installation instructions

GeneralDuring commissioning and operation, the axial piston unit must be filled with hydraulic fluid and air bled. This must also be observed following a relatively long standstill as the axial piston unit may drain back to the reservoir via the hydraulic lines.

Particularly in the installation position "drive shaft upwards" filling and air bleeding must be carried out completely as there is, for example, a danger of dry running.

The case drain fluid in the pump housing must be directed to the reservoir via the highest available drain port (T1, T2).

For combinations of multiple units, make sure that the respec-tive case pressure in each unit is not exceeded. In the event of pressure differences at the drain ports of the units, the shared drain line must be changed so that the minimum permissible case pressure of all connected units is not exceeded in any situation. If this is not possible, separate drain lines must be laid if necessary.

To achieve favorable noise values, decouple all connecting lines using elastic elements and avoid above-reservoir installa-tion.

In all operating conditions, the suction and drain lines must flow into the reservoir below the minimum fluid level. The permissible suction height hS results from the overall loss of pressure; it must not, however, be higher than hS max = 800 mm. The minimum suc-tion pressure at port S must also not fall below 0.8 bar absolute during operation and during cold start.

Installation positionSee the following examples 1 to 8. Further installation positions are possible upon request.

Recommended installation positions: 1 and 2.

NoteWith sizes 10 to 180 with installation position "shaft upward", an air-bleed port R is required (state in plain text when ordering - special version). With size 250, port U is provided as stan-dard in the area near the bearings for air bleeding.

amin When designing the reservoir, ensure adequate space between the suction line and the drain line. This prevents the heated, return flow from being drawn directly back into the suction line.



Above-reservoir installation

Above-reservoir installation means that the axial piston unit is installed above the minimum fluid level of the reservoir.

Recommendation for installation position 8 (drive shaft up-ward): A check valve in the drain line (cracking pressure 7.5 psi (0.5 bar)) can prevent draining of the pump housing.

Details regarding the choice of hydraulic fluid

The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in an open circuit, the reservoir temperature.

The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range (νopt see shaded area of the selection diagram). We recommended that the higher viscosity class be selected in each case.

Example: At an ambient temperature of X °C, an operating tem-perature of 60 °C is set in the circuit. In the optimum operating viscosity range (νopt., shaded area), this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68.

NoteThe case drain temperature, which is affected by pressure and speed, can be higher than the reservoir temperature. At no point of the component may the temperature be higher than 115 °C. The temperature difference specified below is to be taken into account when determining the viscosity in the bear-ing.

If the above conditions cannot be maintained due to extreme operating parameters, we recommend flushing the case at port U (sizes 250 to 1000).

Technical dataFiltration of the hydraulic fluidFiner filtration improves the cleanliness level of the hydraulic fluid, which increases the service life of the axial piston unit.

To ensure the functional reliability of the axial piston unit, a gra-vimetric analysis of the hydraulic fluid is necessary to determine the amount of solid contaminant and to determine the cleanli-ness level according to ISO 4406. A cleanliness level of at least 20/18/15 is to be maintained.

At very high hydraulic fluid temperatures (90 °C to maximum 115 °C), a cleanliness level of at least 19/17/14 according to ISO 4406 is necessary.

If the above classes cannot be achieved, please contact us.

Shaft seal

Permissible pressure loading

The service life of the shaft seal is influenced by the speed of the axial piston unit and the case drain pressure (case pres-sure). The mean differential pressure of 2 bar between the case and the ambient pressure may not be enduringly exceed-ed at normal operating temperature. For a higher differential pressure at reduced speed, see diagram. Momentary pressure spikes (t < 0.1 s) of up to 10 bar are permitted. The service life of the shaft seal decreases with an increase in the frequency of pressure spikes.

The case pressure must be equal to or higher than the ambient pressure.

Definition

Nominal pressure pnom



The maximum pressure corresponds to the maximum operat-ing pressure within the single operating period. The sum of the single operating periods must not exceed the total operating period.

Minimum pressure (high-pressure side)Minimum pressure at the high-pressure side (A or B) which is required in order to prevent damage to the axial piston unit.

Minimum pressure (inlet)Minimum pressure at suction port S (inlet) which is required in order to prevent damage to the axial piston unit. The minimum pressure is dependent on the speed of the axial piston unit (see diagram on page 7).


Maximum permissible rate of pressure rise and reduction dur-ing a pressure change over the entire pressure range.

The values are valid: 1)

- at an absolute pressure pabs = 1 bar at suction port S - for the optimum viscosity range from νopt = 16 to 36 mm2/s - with hydraulic fluid based on mineral oilsMaximum speed (limiting speed) with increased inlet pressure 2)

pabs at suction port S, see adjacent diagram.Torque without radial force, with radial force see page 83)

Torque at 4) Dp = 315 bar

NoteOperation above the maximum values or below the minimum val-ues may result in a loss of function, a reduced service life or in the destruction of the axial piston unit. Other permissible limit values, with respect to speed variation, reduced angular acceleration as a function of the frequency and the permissible start up angular ac-celeration (lower than the maximum angular acceleration) can be found in data sheet RE 90261.

Technical dataEffect of radial force Fq on the service life of bearings

By selecting a suitable direction of radial force Fq, the load on the bearings, caused by the internal rotary group forces can be reduced, thus optimizing the service life of the bearings. Rec-ommended position of mating gear is dependent on direction of rotation. Examples:

Installation instructionsGeneralDuring commissioning and operation, the axial piston unit must be filled with hydraulic fluid and air bled. This must also be observed following a relatively long standstill as the axial piston unit may drain back to the reservoir via the hydraulic lines.

Particularly in the installation position "drive shaft upwards" filling and air bleeding must be carried out completely as there is, for example, a danger of dry running.

The case drain fluid in the motor housing must be directed to the reservoir via the highest available drain port (T1, T2).

For combinations of multiple units, make sure that the respec-tive case pressure in each unit is not exceeded. In the event of pressure differences at the drain ports of the units, the shared drain line must be changed so that the minimum permissible case pressure of all connected units is not exceeded in any situation. If this is not possible, separate drain lines must be laid if necessary.


In all operating conditions, the suction and drain lines must flow into the reservoir below the minimum fluid level. The permissible suction height hS results from the overall loss of pressure; it must not, however, be higher than hS max = 800 mm. The minimum suc-tion pressure at port S must also not fall below 0.8 bar absolute during operation and during cold start.

Installation positionSee the following examples 1 to 8. Further installation positions are possible upon request.



Below-reservoir installation means that the axial piston unit is installed outside of the reservoir below the minimum fluid level.

Fluid

To review the application of A4FO pumps with the selected hydraulicfluid, detailed fluid compatibility and application data can be foundin data sheets RE 90220 (mineral oil), RE 90221 (environmentallyacceptable hydraulic fluids) and RE 90223 (fire resistant fluids, HF).

When using HF- or environmentally acceptable hydraulic fluidspossible limitations for the technical data have to be taken intoconsideration. If necessary please consult our technical department(please indicate type of the hydraulic fluid used for your applicationon the order sheet).Sizes 16...40 of fixed pump A4FO are not suitable for operation withHFA, HFB or HFC-fluids.

Operating viscosity range

In order to optain optimum efficiency and service life, we recommendthat the operating viscosity (at operating temperature) be selectedfrom within the range:

νopt = operating viscosity 16...36 mm2/s

referred to the tank temperature (open circuit).

Viscosity limits

The limiting values for viscosity are as follows:

Sizes 16...40νmin = 5 mm2/s,

short term at a max. permissible temperature of tmax = 115°C

νmax = 1600, short term on cold start (tmin = -40°C)

Sizes 71...500νmin = 10 mm2/s,

short term at a max. permissible leakage oil temp. of tmax = 90°νmax = 1000 mm2/s, short term on cold start (tmin = -25°C)

Please note that the max. fluid temperature is also not exceeded incertain areas (for instance bearing area).

At temperatures of -25°C up to -40°C special measures may berequired for certain installation positions. Please contact us.

Notes on the selection of the hydraulic fluid

In order to select the correct fluid, it is necessary to know the operatingtemperature in the tank (open circuit) in relation to the ambienttemperature.

The hydraulic fluid should be selected so that within the operatingtemperature range, the operating viscosity lies within the optimumrange (νopt) (see shaded section of the selection diagram). Werecommend that the highest possible viscosity range should be chosenin each case.

Example: At an ambient temperature of X°C the operatingtemperature is 60°C. Within the operating viscosity range (νopt;shaded area), this corresponds to viscosity ranges VG 46 or VG 68.VG 68 should be selected.

Important: The leakage oil (case drain oil) temperature is influencedby pressure and pump speed and is always higher than the tanktemperature. However, at no point in the circuit may the temperatureexceed 115°C for sizes 16…40 or 90°C for sizes 71…500.

If it is not possible to comply with the above conditions because ofextreme operating parameters or high ambient temperatures pleaseconsult us.

Filtration

The finer the filtration the better the achieved cleanliness level of thepressure fluid and the longer the life of the axial piston unit.

To ensure the functioning of the axial piston unit a minimumcleanliness level of

9 to NAS 163818/15 to ISO/DIS 4406 is necessary.

Installation and Commissioning Guidelines,Sizes 71...500

see RE 92050 (A4VSO)

Installation and Commissioning Guidelines, Sizes 16...40

General

At start-up and during operation the pump housing has imperativelyto be filled up with hydraulic fluid (filling of the case chamber). Start-up has to be carried out at low speed and without load till the systemis completely bleeded.

At a longer standstill the case may discharge via operating line. Atnew start-up a sufficient filling of the housing has to be granted.

The min. suction pressure at port S should not fall below 0,8 barabsolute.

Installation positionShaft horizontally resp. to the bottom. When mounting on top of thetank the installation position ”shaft horizontally, suction port to thebottom” is not admssible!

Installation below tank levelPumps below min. oil level in the tank (standard)

➔ Fill up axial piston pump before start-up via highest positionedcase drain port

➔ Recommendation: Fill up suction lines

➔ Operate pump at low speed (igniton speed) till pump system iscompletely filled up

➔ Minimum immersion depth of the suction line or drain line inthe tank: 200 mm (relative to the min. oil level in the tank).

Function and assembly of variable-speed drivesRexroth has developed the proven axial piston units of the A10 product family further for use in energy-efficient variable-speed drive systems and optimized the interplay between the electric motor and the pump. The especially robust units are employed for small to medium sizes and satisfy individual requirements with their numerous combination options. Variable-speed pump drives featuring Rexroth BlueHydraulics technology reduce energy consumption in industrial applica-tions and at the same time avoid medium-level noise emissions. At the same time, the familiar performance is retained or even improved. The extensive spectrum of different variable-speed pump drives from Rexroth includes ready-to-use solutions that are finely scalable in both function and power. The energy-effi-cient hydraulic drive can be realized with internal gear pumps, fixed or variable axial piston units. Equipped with a suitable controller, exactly the required flow and pressure are provided which are needed at the machine.

The proven axial piston units have been developed further for use in speed-controlled drives. These are approved for start/stop operation and for changing directions of rotation. At the lowest speeds, between 0 and 200 rpm, they provide a con-stant pressure and are characterized by very high efficiency in pressure retention operation. Efficiency is achieved optimized by either a fixed or variable displacement, depending on the re-quirements of the cycle. The A10 units can be used as pumps and as motors in single-, double- or four-quadrant operation. For the implementation of variable-speed drives, the new axial piston units offer numerous options for combination. The axial piston fixed displacement units A10FZO and A10FZG cover the sizes 6 to 63 cm3. The axial piston variable displacement units are available in the sizes 10 to 180 cm3 (A10VZO). Equipped with a torque controller and 2-point control, they are employed for dimensioning smaller servomotors. The numerous combination options allow a wide range of different customized system requirements to be satisfied.

Technical dataHydraulic fluid

Prior to project design, please see our data sheets RE 90220 (mineral oil) and RE 90221 (environmentally acceptable hydraulic fluids) for detailed information on hydraulic fluid and operating conditions.

When using environmentally acceptable hydraulic fluids, the limitations regarding technical data and seals must be observed. Please contact us. When ordering, indicate the hydraulic fluid that is to be used.


We recommend you to choose the operating viscosity (at operating temperature) in the optimum range for efficiency and useful life of

nopt = opt. operating viscosity 16 ... 36 mm2/s

taking into account the reservoir temperature (open circuit) or circuit temperature (closed circuit).

Limits of viscosity range

For critical operating conditions the following values apply:

nmin = 10 mm2/s for short periods (t ≤ 1 min) at a max. perm. case drain temperature of 90 °C.

Note that the maximum case drain temperature of 90 °C may not be exceeded even locally (e.g. in the bearing area). The temperature in the bearing area is approx. 5 K higher than the average case drain temperature.

nmax = 1600 mm2/s for short periods (t ≤ 1 min) on cold start (p ≤ 30 bar, n ≤ 1000 rpm, tmin -25 °C)

Depending on the installation situation, special measures are necessary at temperatures between -40 °C and -25 °C. Please contact us.

For detailed information about operation with low temperatures, see RE 90300-03-B.

Selection diagram


In order to select the correct fluid, it is necessary to know the operating temperature in the reservoir (open circuit) in relation to the ambient temperature: in an open circuit, the reservoir temperature; in a closed circuit, the circuit temperature.

The hydraulic fluid should be selected so that the viscosity in the operating temperature range is within the optimum range (nopt), see shaded area of the selection diagram. We recom-mended that the higher viscosity class be selected in each case.

Example: at an ambient temperature of X °C, an operating tem-perature of 60 °C is set in the circuit. In the optimum operating viscosity range (nopt, shaded area), this corresponds to the viscosity classes VG 46 or VG 68. VG 68 should be selected.

Note The case drain temperature, which is influenced by pressure and speed, is always higher than the reservoir temperature. However, at no point in the component may the temperature exceed 90 °C. The temperature difference specified on the left is to be taken into account when determining the viscosity in the bearing.

If the above conditions cannot be met due to extreme operat-ing parameters, please contact us.

Filtration of the hydraulic fluidThe finer the filtration, the better the hydraulic fluid cleanliness class, and the longer the service life of the axial piston unit.

In order to guarantee the functional reliability of the axial piston unit, it is necessary to carry out a gravimetric evaluation of the hydraulic fluid to determine the particle contamination and the cleanliness class according to ISO 4406. The minimum cleanli-ness class to be observed is 20/18/15. At very high hydraulic fluid temperatures (90 °C to maximum 115 °C), a cleanliness class of at least 19/17/14 according to ISO 4406 is necessary.

If the above classes cannot be maintained, please contact us.

DefinitionNominal pressure pnom



The maximum pressure corresponds to the maximum operating pressure within the individual operating period. The sum of the individual operating periods must not exceed the total operat-ing period.

Minimum pressure (high-pressure side)Minimum pressure on high-pressure side (A or B) that is re-quired to prevent damage to the axial piston unit.

Minimum pressure (inlet) open circuitMinimum pressure at suction port S (inlet) that is required to prevent damage to the axial piston unit. The minimum pressure depends on the speed and displacement of the axial piston unit.

Minimum pressure (low-pressure side) closed circuitMinimum pressure on the low-pressure side (A or B) that is required to prevent damage to the axial piston unit.


Maximum permissible rate of pressure build-up and pressure reduction with a pressure change over the entire pressure range.

The pressure control limits the maximum pressure at the pump output within the pump control range. The variable pump only supplies as much hydraulic fluid as is required by the con sumers. If the operating pressure exceeds the pressure setpoint set at the integrated pressure valve, the pump will adjust towards a smaller displacement. The pressure can be set steplessly at the control valve.

Please contact us with respect to applications with pressure control and changing direction of rotation.

The DRG control valve overrides the function of the DR pressure control, see page 18.

A pressure-relief valve can be externally connected to port X as a remote control. This pressure-relief valve is included in the delivery contents of the DRG control.

The differential pressure at the control valve is set as standard to 20 bar. The pilot oil flow at port X is approx. 1.5 l/min. If another setting is required (range 10 to 22 bar), please state in clear text.

As a separate pressure-relief valve we recommend:

DBDH 6 (hydraulic) as per RE 25402 or DBETR-SO 381 with orifice Ø 0.8 mm in P (electric) to RE 29166.

The maximum line length must not exceed 2 m.

Please contact us with respect to applications with remotely operated pressure control and changing direction of rotation.

LA.D-Pressure/torque controller (A10VZO)Pressure control equipment as DR, see page 18.

In order to achieve a constant drive torque with varying operat-ing pressure, the swivel angle and with it the output flow from the axial piston pump is varied so that the product of flow and pressure remains constant.

The torque characteristics are set at the plant. Please state in clear text, e.g. T = 50 Nm.

Control data

For data and notes about the DR pressure control, see page 18.

For data and notes about the remotely operated DRG pressure control, see page 19.

EZ-Two-point control, electric (A10VZO, A10VZG)The variable displacement unit is set to minimum swivel angle by operating the switching solenoids. This supplies control pressure to the stroke piston via the switching valve.

The control pressure is taken internally from the respective high-pressure side, whereby a minimum operating pressure differential of DpA,B ≥ 20 bar is required.

The axial piston unit can only be activated between Vg max and Vg min.

Please state Vg min default setting in clear text when ordering.

Installation notesGeneral

The axial piston unit must be filled with hydraulic fluid and air bled during commissioning and operation. This must also be observed following a longer standstill as the axial piston unit empty via the hydraulic lines.

Especially with the installation position "drive shaft upwards" or "drive shaft downward", attention must be paid to a com-plete filling and air bleeding since there is a risk, for example, of dry running.

The case drain fluid in the case interior must be directed to the reservoir via the highest case drain port (L1, L2, L3).

For combinations comprising several units, make sure that the respective case pressure is not exceeded. If there is a pressure difference at case drain port L, each pump is to be fitted with a separate case drain line.


In all operating states, the suction line and case drain line must flow into the reservoir below the minimum fluid level . The permissible suction height hS is a result of the overall pressure loss, but may not be greater than hS max = 800 mm. The minimum suction pressure at port S of pS min = 0.8 bar absolute must not be exceeded in operation.


See the following examples 1 to 12. Additional installation positions are available upon request.



Below-reservoir installation means the axial piston unit is in-stalled outside of the reservoir below the minimum fluid level.

amin When designing the reservoir, ensure adequate distance between the suction line and the case drain line. This prevents the heated, return flow from being drawn directly back into the suction line.


Above-reservoir installation means the axial piston unit is installed above the minimum fluid level of the reservoir. To prevent the axial piston unit from draining, a height differ-ence hES min of at least 25 mm is required in installation position 6

Observe the maximum permissible suction height hS max = 800 mm.

A check valve in the case drain line is only permissible in indi-vidual cases. Consult us for approval.

General informationThe axial piston units A10FZO and A10VZO are designed to be used in open circuits. –The axial piston unit A10FZG and A10VZG is specified for use in closed circuits.

Project planning, assembly and commissioning of the axial piston unit require the involvement of qualified personnel. –

Before operating the axial piston unit, please read the appropriate operating instructions thoroughly and completely. –If necessary, request these from Rexroth.

During and shortly after operation, there is a risk of burns on the axial piston unit and especially on the solenoids. –Take appropriate safety measures (e.g. by wearing protective clothing).

Depending on the operating conditions of the axial piston unit (operating pressure, fluid temperature), the – characteristics may shift.


The ports and fixing - threads are designed for the specified maximum pressure. The machine or system manufacturer must ensure that the connecting elements and lines correspond to the specified operating conditions (pressure, flow, hydraulic fluid, temperature) with the necessary safety factors.

The service line ports and function ports are only designed to accommodate hydraulic lines. -

Pressure cut-off and pressure control – do not provide security against pressure overload. A separate pressure relief valve is to be provided in the hydraulic system.


The product is not approved as a component for the safety concept of a general machine according to DIN EN ISO 13849. –

Function and assembly of variable-speed drivesRexroth has developed the proven axial piston units of the A10 product family further for use in energy-efficient variable-speed drive systems and optimized the interplay between the electric motor and the pump. The especially robust units are employed for small to medium sizes and satisfy individual requirements with their numerous combination options. Variable-speed pump drives featuring Rexroth BlueHydraulics technology reduce energy consumption in industrial applica-tions and at the same time avoid medium-level noise emissions. At the same time, the familiar performance is retained or even improved. The extensive spectrum of different variable-speed pump drives from Rexroth includes ready-to-use solutions that are finely scalable in both function and power. The energy-effi-cient hydraulic drive can be realized with internal gear pumps, fixed or variable axial piston units. Equipped with a suitable controller, exactly the required flow and pressure are provided which are needed at the machine.

The proven axial piston units have been developed further for use in speed-controlled drives. These are approved for start/stop operation and for changing directions of rotation. At the lowest speeds, between 0 and 200 rpm, they provide a con-stant pressure and are characterized by very high efficiency in pressure retention operation. Efficiency is achieved optimized by either a fixed or variable displacement, depending on the re-quirements of the cycle. The A10 units can be used as pumps and as motors in single-, double- or four-quadrant operation. For the implementation of variable-speed drives, the new axial piston units offer numerous options for combination. The axial piston fixed displacement units A10FZO and A10FZG cover the sizes 6 to 63 cm3. The axial piston variable displacement units are available in the sizes 10 to 180 cm3 (A10VZO). Equipped with a torque controller and 2-point control, they are employed for dimensioning smaller servomotors. The numerous combination options allow a wide range of different customized system requirements to be satisfied.

Technical dataHydraulic fluid

Prior to project design, please see our data sheets RE 90220 (mineral oil) and RE 90221 (environmentally acceptable hydraulic fluids) for detailed information on hydraulic fluid and operating conditions.

When using environmentally acceptable hydraulic fluids, the limitations regarding technical data and seals must be observed. Please contact us. When ordering, indicate the hydraulic fluid that is to be used.


We recommend you to choose the operating viscosity (at operating temperature) in the optimum range for efficiency and useful life of

nopt = opt. operating viscosity 16 ... 36 mm2/s

taking into account the reservoir temperature (open circuit) or circuit temperature (closed circuit).

Limits of viscosity range

For critical operating conditions the following values apply:

nmin = 10 mm2/s for short periods (t ≤ 1 min) at a max. perm. case drain temperature of 90 °C.

Note that the maximum case drain temperature of 90 °C may not be exceeded even locally (e.g. in the bearing area). The temperature in the bearing area is approx. 5 K higher than the average case drain temperature.

nmax = 1600 mm2/s for short periods (t ≤ 1 min) on cold start (p ≤ 30 bar, n ≤ 1000 rpm, tmin -25 °C)

Depending on the installation situation, special measures are necessary at temperatures between -40 °C and -25 °C. Please contact us.

For detailed information about operation with low temperatures, see RE 90300-03-B.

Selection diagram


In order to select the correct fluid, it is necessary to know the operating temperature in the reservoir (open circuit) in relation to the ambient temperature: in an open circuit, the reservoir temperature; in a closed circuit, the circuit temperature.

The hydraulic fluid should be selected so that the viscosity in the operating temperature range is within the optimum range (nopt), see shaded area of the selection diagram. We recom-mended that the higher viscosity class be selected in each case.

Example: at an ambient temperature of X °C, an operating tem-perature of 60 °C is set in the circuit. In the optimum operating viscosity range (nopt, shaded area), this corresponds to the viscosity classes VG 46 or VG 68. VG 68 should be selected.

Note The case drain temperature, which is influenced by pressure and speed, is always higher than the reservoir temperature. However, at no point in the component may the temperature exceed 90 °C. The temperature difference specified on the left is to be taken into account when determining the viscosity in the bearing.

If the above conditions cannot be met due to extreme operat-ing parameters, please contact us.

Filtration of the hydraulic fluidThe finer the filtration, the better the hydraulic fluid cleanliness class, and the longer the service life of the axial piston unit.

In order to guarantee the functional reliability of the axial piston unit, it is necessary to carry out a gravimetric evaluation of the hydraulic fluid to determine the particle contamination and the cleanliness class according to ISO 4406. The minimum cleanli-ness class to be observed is 20/18/15. At very high hydraulic fluid temperatures (90 °C to maximum 115 °C), a cleanliness class of at least 19/17/14 according to ISO 4406 is necessary.

If the above classes cannot be maintained, please contact us.

The pressure control limits the maximum pressure at the pump output within the pump control range. The variable pump only supplies as much hydraulic fluid as is required by the con sumers. If the operating pressure exceeds the pressure setpoint set at the integrated pressure valve, the pump will adjust towards a smaller displacement. The pressure can be set steplessly at the control valve.

Please contact us with respect to applications with pressure control and changing direction of rotation.

The DRG control valve overrides the function of the DR pressure control, see page 18.

A pressure-relief valve can be externally connected to port X as a remote control. This pressure-relief valve is included in the delivery contents of the DRG control.

The differential pressure at the control valve is set as standard to 20 bar. The pilot oil flow at port X is approx. 1.5 l/min. If another setting is required (range 10 to 22 bar), please state in clear text.

As a separate pressure-relief valve we recommend:

DBDH 6 (hydraulic) as per RE 25402 or DBETR-SO 381 with orifice Ø 0.8 mm in P (electric) to RE 29166.

LA.D-Pressure/torque controller (A10VZO)Pressure control equipment as DR, see page 18.

In order to achieve a constant drive torque with varying operat-ing pressure, the swivel angle and with it the output flow from the axial piston pump is varied so that the product of flow and pressure remains constant.

The torque characteristics are set at the plant. Please state in clear text, e.g. T = 50 Nm.

Control data

For data and notes about the DR pressure control, see page 18.

EZ-Two-point control, electric (A10VZO, A10VZG)The variable displacement unit is set to minimum swivel angle by operating the switching solenoids. This supplies control pressure to the stroke piston via the switching valve.

The control pressure is taken internally from the respective high-pressure side, whereby a minimum operating pressure differential of DpA,B ≥ 20 bar is required.

The axial piston unit can only be activated between Vg max and Vg min.

Please state Vg min default setting in clear text when ordering.

De-energized = Vg max

Current energized = Vg min

Installation notesGeneral

The axial piston unit must be filled with hydraulic fluid and air bled during commissioning and operation. This must also be observed following a longer standstill as the axial piston unit empty via the hydraulic lines.

Especially with the installation position "drive shaft upwards" or "drive shaft downward", attention must be paid to a com-plete filling and air bleeding since there is a risk, for example, of dry running.

The case drain fluid in the case interior must be directed to the reservoir via the highest case drain port (L1, L2, L3).

For combinations comprising several units, make sure that the respective case pressure is not exceeded. If there is a pressure difference at case drain port L, each pump is to be fitted with a separate case drain line.


In all operating states, the suction line and case drain line must flow into the reservoir below the minimum fluid level . The permissible suction height hS is a result of the overall pressure loss, but may not be greater than hS max = 800 mm. The minimum suction pressure at port S of pS min = 0.8 bar absolute must not be exceeded in operation.


See the following examples 1 to 12. Additional installation positions are available upon request.



Below-reservoir installation means the axial piston unit is in-stalled outside of the reservoir below the minimum fluid level.

amin When designing the reservoir, ensure adequate distance between the suction line and the case drain line. This prevents the heated, return flow from being drawn directly back into the suction line.


Above-reservoir installation means the axial piston unit is installed above the minimum fluid level of the reservoir. To prevent the axial piston unit from draining, a height differ-ence hES min of at least 25 mm is required in installation position 6

Observe the maximum permissible suction height hS max = 800 mm.

A check valve in the case drain line is only permissible in indi-vidual cases. Consult us for approval.
