Reservoir pump units of the KFG series (S) (C)for industrial use in automatic oil or grease lubrication systems

General InformationPump units of the KFG, KFGS and KFGC (CAN bus) series are electrically driven reservoir pump units available with and without an in-tegrated control unit. The pump provides on-demand lubricant supply to centralized lubri-cation systems with progressive feeders or single-line distributors on machines, systems and vehicles. The pump units differ in terms of the size and type of lubricant reservoir, the lubricant filling and their control and function monitoring. Powerful CAN bus versions allow one unit and a special valve to supply up to four independent zones according to demand.

Distinguishing features of the pump unitsIn contrast with the KFG pump unit, which can only be equipped with external pump control, the KFGS pump unit contains an in-ternal control unit. This control unit can con-figure basic settings such as pump cycle time (timer operation) or lubricant pulse cycles (counter operation). Fill level control is also monitored by the pump control unit. The KFGC (CAN bus) version is based on the KFGS series. Further, it is capable of controlling up to four independent zones via the CAN bus. The pump can optionally be programmed, operated and its data read via an IRDA inter-face.

KFG pump unit The KFG pump has three lubricant outlets for connecting up to three independent zones. A separate pump element is required for each outlet.

Up to five pump elements with different deliv-ery volumes are available so the delivery rate can be adjusted to the requirements of the individual zones. This provides all lubrication points with the required amount of lubricant during each lubrication cycle.

Pumps in the KFG series have different reser-voir designs and reservoir sizes depending on their field of application.

The pump fill level can be monitored using the integrated rocker switch (W1/W1G for NLGI Grade 2 greases) or, optionally, a capaci-tive fill level switch attached on the cover (W2 for NLGI Grade ≤ 1 greases). The pump is available in various voltage designs. An agita-tor driven by a geared motor ensures lubri-cant can be delivered at temperatures down to -25 °C depending on the medium. There may be restrictions on the components de-pending on the particular conditions in the field of application, e.g. as a stationary pump in industrial sector, as a rotary pump in the wind energy sector or in the commercial ve-hicles sector. This also applies to KFGS and KFGC (CAN bus) pump units.

KFGS pump unitPump units of the KFGS series are reservoir pump units with an integrated control unit based on the KFG. The KFGS pump unit is controlled by the IG502-2-I integrated control and monitoring unit, which can operate based on time or pulses and with or without a mon-itoring function.

This control unit provides the following ad-vantages:

Non-volatile memory with PIN code • protectionRecording of remaining intervals and • remaining lubrication timesRecording of fault notifications (diagnostics • memory) Data backup in case of voltage failure • Connectivity for external pushbutton • Connectivity for inductive piston detector• Interval time and contact time can be • adjusted in dependently, including on monitored systems. Easy electrical connection using plug con-• nectors

Interval times (timer), interval pulses (counter) and pump cycle times (contact) can be en-tered through a display. A piston detector is used to monitor the feeding operation on pro-gressive systems; a pressure switch is used for single-line systems. The KFGS pump unit is available in the same reservoir designs, reservoir sizes and voltage designs as the KFG series.

KFGC (CAN bus) pump unitPump units of the KFGC (CAN bus) series are pump units from the KFG series with an inte-grated CAN bus control unit.

The LC-CAN5000 control units offer the fol-lowing special features:

CAN bus interface (SAE J1939), which al-• lows units to be seamlessly integrated into the CAN bus networks. The lubrication system can be monitored, • operated and configured through the CAN bus. There is also the option of configuring and • independently operating the pump unit via the IRDA interface.

The control unit is still able to control up to four independent zones and to supply them from a single pump unit. To achieve this capa-bility, electric switch valves which are con-trolled based on the parameters set for each individual lubrication zone are placed in the main line. The control unit has up to four sol-id-state switching outputs for this purpose. Aside from valve control, the outputs can also be configured as digital outputs for other pur-poses. In addition to the above-mentioned outputs, up to four digital inputs are available, e.g. for monitoring piston detectors, pressure switches or other switching contacts.

KFGS control unit Pump units of the KFGS series are equipped with an integrated IG502-2-I control unit with a control display. Parameters for interval times (timer), interval pulses (counter) and pump cycle times (contact) can be entered through the control unit.

DesignPump units of the KFG, KFGS and KFGC (CAN bus) series are characterized by their compact construction and are divided into the assem-blies for pump housing, lubricant reservoir, control unit and fill level monitoring. A short description of the individual assemblies fol-lows below.

Pressure regulating valve To protect the components of progressive systems from overpressure damage, a pres-sure regulating valve must be integrated into the pump element. If the operating pressure exceeds the cracking pressure of the pres-sure regulating valve, the valve opens and the lubricant flows back (on versions with a return line) into the lubricant reservoir. The pressure regulating valve is installed on the pump element. On single-line systems, the pressure regulating valve is integrated into the pressure relief valve.

Assembly holes A mounting flange with assembly holes is present on the back of the pump housing on all pump versions.

Pump element with pressure regulating valve

Pump element The pump element(s) meter the lubricant then pass it to the downstream lubrication points or feeders. Five different pump ele-ments with a delivery volume ranging from 0.8 to 5 cm3/min. are available to provide the required quantity of lubricant.

Lubricant reservoir

The lubricant reservoir is available in 2 kg, 6 kg and 10 kg sizes. The reservoirs are made of transparent plastic and have fill level mark-ings that allow the fill level to be monitored visually. The pump fill level can be monitored using an integrated rocker switch or, option-ally, an inductive level switch attached to the cover.

Pump housing

The pump housing contains, among other things, the pump drive, control unit (KFGS) and three lubricant outlets for installing a maximum of three pump elements. One pressure regulating valve can be attached to each pump element. When used in single-line systems, a pressure relief valve is also at-tached to the pump element together with a pressure regulating valve. A conical head nip-ple can optionally be attached to the pump housing using the alternative connections to fill the pump. A filler socket or grease return can also be attached. A display and control screen is mounted on the front side of the KFGS design, while the KFGC (CAN bus) design has a display at-tached. An IRDA interface is integrated into this, which can optionally be used to program the pump. Depending on the pump version and voltage design, the electrical connections are located on the left front and/or the underside of the pump housing.

Functional description of progressive system with KFG pump unit A general progressive feeder system consists of the following components:

Pump unit with pump element and pres-• sure regulating valveLubricant lines, consisting of main and • possibly branch lines Progressive feeders •

When the pump motor is turned on, the pis-ton pump delivers lubricant from the lubricant reservoir to the lubricant outlet. The pump el-ement attached to the outlet delivers the lu-bricant further, into the downstream main line. The lubricant flows through the main line to the progressive feeder. There, the lubricant is distributed according to the volume required by the lubrication point being supplied.

In progressive systems with a master feeder and secondary feeder, the lubricant coming from the pump unit is delivered to the master feeder. The master feeder distributes the lubricant to the secondary feeders according to their individual volume requirements. From there, the lubricant flows to the lubrication points.

Functional description of progressive system with KFGC (CAN bus) pump unitThe general functional description for pro-gressive systems with a KFGS pump unit also applies for the design with CAN bus pump control. The integrated LC-CAN5000 control unit permits the lubrication circuit of a pro-gressive feeder system to be distributed into individual lubrication zones for which individ-ual parameters (e.g. contact and interval times) can be set. Up to four lubrication sec-tions can be installed in total. To distribute the lubricant, a corresponding number of electric switch valves is installed in the lubricant line leading from the pump element. A valve is opened as soon as the control unit starts a pump cycle period for the corresponding lu-brication segment. The pump can only pro-vide one lubrication segment with adequate lubrication, so it must be ensured that only one valve is opened during operation. This is handled by the control unit in automatic and semiautomatic operation.

A 5/4 directional solenoid valve can optionally be used in place of single valves.

Functional description of single-line system with KFG pump unit A general single-line system consists of the following components: pump unit with pump element, pressure relief valve with integrated pressure regulating valve, main lubricant line and single-line feeders. When the pump mo-tor is turned on, the piston pump delivers lu-bricant from the reservoir to the lubricant outlet. The pump element attached to the outlet meters the lubricant and delivers it fur-ther through the pressure relief valve at-tached to the pump element on to the main line. The lubricant flows through the main line to the single-line distributors, where it is me-tered and passed to the lubrication points. This is performed during or after the pump cycle time, depending on the type of feeders used (prelubrication or relubrication feeders). The pressure relief valve switches after me-tering is complete. After the main line has been relieved, the single-line distributors are again premetered and the pump unit is now prepared for another lubrication cycle.

Functional description of single-line system with KFGC (CAN bus) pump unitThe general functional description for single-line systems with a KFG pump unit also ap-plies for the design with CAN bus pump con-trol. The integrated LC-CAN 5000 control unit permits the lubrication circuit of a single-line feeder system to be distributed into individual lubrication zones for which individual param-eters (e.g. contact and interval times) can be set. Up to four lubrication zones can be in-stalled in total. To distribute the lubricant, a corresponding number of electric switch valves is installed in the lubricant line leading from the pump element. A valve is opened as soon as the control unit starts a pump cycle period for the corresponding lubrication seg-ment. The pump can only provide one lubri-cation segment with adequate lubrication, so it must be ensured that only one valve is opened during operation. This is handled by the control unit in automatic and semiauto-matic operation. When CAN commands are used for control, the valve opening must be ensured by selecting the appropriate contact and interval times or by using appropriately programmed processes in the external lubri-cation program which switches the valves in a carefully coordinated sequence so that only one lubrication zone is activated at a time.

Pin Description 1 = + Supply voltage 2 = Signal output (pulses) 3 = not assigned 4 = not assigned

Functional description

The W1/W1G fill level switches described below are designed as rocker switches and are inte-grated in the bottom of the reservoir. A magnetic rocker mounted on the agitator is turned downward by the grease resistance when the reservoir is full and the agitator rotates. On the W1 version, a pulse is created at each revolution; in contrast, versions with signal smoothing (W1G) keep a constant signal. When the minimum fill level is reached, the resistance the grease exerts on the rocker subsides. The rocker turns back and the pulse (W1) or signal (W1G) sequence is interrupted.

Function: (Standard "TIMER" function without monitoring)The lubrication intervals are repeated cycli-cally after the set interval (tPA or cPA). The pump cycle time during a lubrication proce-dure corresponds to the time configured on the control panel as tCO (contact time) in minutes.Interval and pump cycle times pro-ceed only in the presence of supply voltage (attach connection 15 and 31 to 12 V DC or 24 V DC depending on unit). When the supply voltage is turned off (power supply on con-nection 15 is interrupted), the current interval time is saved and continued once the supply voltage is turned on again. When the moni-toring function CS is programmed (only for centralized lubrication systems with cycle switch), the piston detector mounted on a progressive feeder is queried for a signal dur-ing the pump cycle time. If this signal is ab-sent during the preselected pump cycle time (tCO), a monitoring program (block operation) is started after the cycle time finishes. During this program sequence, the pump unit is turned on up to two times at specially defined intervals and the piston detector is monitored for a signal. If the piston detector signal reaches the control unit, the monitoring pro-gram ends immediately and operation contin-ues as normal. If the monitoring program completes its sequence, a fault notification is issued on completion and the operational se-quence is halted. While the monitoring pro-gram is ongoing, no interim lubrications can be triggered. When the monitoring function PS is programmed (only for centralized lubri-cation systems with pressure switch), the pressure switch monitors pressure build-up at the end of the main lubrication line during the CONTACT time (pump cycle time). A signal is sent to the KFGS control unit when the set pressure is reached.

Storage (EEPROM)The control unit has non-volatile memory (EEPROM), so continuous power supply is not required to store intervals and fault notifica-tions. When the supply voltage is turned off, the current value is saved and will be avail-able for continued operation once the supply voltage is re-established.

Monitoring and fault indicationsFunction monitoring with piston detector or pressure switch Progressive systems can be monitored by a piston detector and single-line systems can be monitored by a pressure switch. To do this, CS (cycle switch, piston de-tector) or PS (pressure switch) must be set as monitoring in COP when the device is config-ured (programmed). The signal from the switch is then monitored during lubrication. If the signal is not sent during the lubrication procedure and the monitoring program it automatically triggers does not start, a fault notification is sent (connection SL2 is con-stantly switched on) after the monitoring pro-gram ends, and the operational sequence is interrupted. When monitoring is performed by a pressure switch (PS), a fault notification would be sent directly after conclusion of the monitoring time. In contrast with the CS set-ting, there is no monitoring program (block operation) in this case. The error code FCS (Fault Cycle Switch), FPS (Fault Pressure Switch) or FLL (Fault Low Level) can be viewed by pressing a key on the control panel.

GeneralThe IG502-2-I control and monitoring de-vice is an integral component of the KFGS pump unit. Its functions are specially de-signed to control and monitor centralized lu-brication systems. The customer can pro-gram the control unit to adapt it to the par-ticular operating conditions of the machine/system.

Pause (tPA) in "TIMER" modeThe interval (time period between two lubri-cations) in the "TIMER" mode is determined based on a time interval generated by the control unit and the value programmed as the tPA. Its value can be set from 0.1 h to 99.9 h.

Pause (cPA) in "COUNTER" modeThe pause (duration between two lubrica-tions) in "COUNTER" mode is determined based on the duration of the pulses received at connection DK (signal change from0 V to 24 V) and by the value programmed as the cPA. Its value can be set from 1 to 999 puls-es. In this mode, the DK connection leading from the unit is used as a clock pulse input to trigger lubrications after a specified num-ber of pulses. In this case, an external push-button cannot be used to trigger interim lu-brications.

The W1 fill level switch described below is de-signed as a rocker switch and is integrated in the bottom of the reservoir. A magnetic rocker mounted on the agitator is turned downward by the grease resistance when the reservoir is full and the agitator rotates. A pulse is created at each revolution of the agitator. When the minimum fill level is reached, the resistance the grease exerts on the rocker subsides. The rocker turns back and the pulses are inter-rupted.


The W2 fill level switch described below is designed as a capacitive inductive actuator for fluid greases and is integrated into the reservoir cover.

In contrast to the KFG pump unit, on which the fill level signal is evaluated externally, the internal pump control unit on the KFGS pump unit evaluates the fill level of the W1 control.

A fill level indicator light can optionally be connected through the 4-pin plug on the bottom of the pump (see connectivity on page 17).

NoteThe W2 fill level switch is not suitable for greases of class ≥ NLG2.The switching point depends on the lubricant being used. Different lubricants can result in different switching points.

Pump units of the KFGC (CAN bus) series are reservoir pump units (piston pumps) with an integrated control unit for on-demand lubri-cant supply to centralized lubrication systems with progressive feeders or to single-line sys-tems. A special feature of pump units of the KFGC (CAN bus) series is the integrated LC-CAN5000 control unit, which is distin-guished by the following characteristics:

CAN bus interface (SAE J1939), which • allows units to be integrated into the CAN bus networks of machines and systems. The lubrication system is monitored, oper-ated and configured through the CAN bus, for example at the process control level.

There is also the option of configuring and • operating the pump unit without a CAN bus connection.

The control unit is able to control and • monitor up to four independent zones and to supply them from a single pump unit.

Electric switch valves which are controlled • based on the parameters set for each individual lubrication zone are placed in the main line. The control unit has up to four solid-state switching outputs for this purpose.

Aside from valve control, the outputs can • also be configured as digital outputs for other purposes.

In addition to the outputs, up to four digital • inputs are available, e.g. for monitoring piston detectors, pressure switches or other switching contacts. A detailed de-scription of the electrical connections can be found in the operating instructions for the KFG series of pumps.

The control unit's comprehensive monitoring functions allow potential faults to be detected early. This includes, among other things, monitoring the fill level in the lubricant reser-voir, monitoring the signal lines on attached components for line breakage, and monitor-ing the switching outputs for short circuits.

Important system events such as a low fill level in the lubricant reservoir are saved by the control unit and given a time stamp. This allows the causes of operational faults to be determined more easily.

The flexible parameters and configuration op-tions allow custom lubrication concepts to be implemented for each individual lubrication zone in the system. The control unit can store up to 16 sets of parameters. Each set of pa-rameters contains all the information required to control and monitor the lubrication pro-cess. This means that different lubrication scenarios can be prepared and saved then called on when needed. The CAN bus control unit is available in the 12/24 V DC designs.
