OPERATING INSTRUCTIONS A. Description A.1 Operating principle : ( For the components positions refer to the enclosed exploded drawings ) The GP / GPM vacuum pumps are single stage, oil-sealed rotary vanes vacuum pumps. The anti-suckback valve , gas-ballast valve ( optional ) exhaust filters and oil reflushing circuit and oil cooling are integrated functional elements. The pumps are driven by a directly flanged motor by means of coupling. The rotor ( pos 201 ) assembled eccentrically to the stator (pos. 202 ) has 3 vanes ( pos. 203 ) dividing the pump chamber into three sections. Ech section’ volume varies periodically during the rotor rotation as the blades, running freely inside the rotor cavities, are pushed, thanks to centrifuge power, toward the cylinder walls. The gas, during the expansion chamber phase, gets sucked thru the suction inlet. The sucked gas flows thru the fine filter and the opened anti-suckback valve ( pos. 204a and 204b ), entering the pumping chamber, where, during the next phase, gets compressed and exhausted thru the oil separator filter together with the nebulized lubrication oil. The oil remover cartridge (pos. 205 ), or more than one depending upon pump model, stops the nebulized oil, flowing into oil filter for being recycled, while the sucked gas, oil mists less, is exhausted thru the exhaust valve ( 206 ) to a slight over-pressure if compared to atmospheric one. The oil injected into the pumping chamber assures tightness, lubrication and pump cooling. The oil cycle is maintained by the pressure difference exhisting between the oil case ( pressure above or equal to atmospheric one ) and the suction ( pressure below to the atmospheric one ). The fan directly connected to motor shaft, grants the pump air cooling flow ( size 45 - 300 ). Pump, upon request, can also be supplied with a gasballast valve. By opening this valve an air flow enters the pumping chamber so as to avoid the condensation of gas or steams. In case of necessity, the gas ballast valve can be fitted afterwards. The anti-suckback valve included in the suction avoids the oil being flushed back when pump gets stopped. A.2 Field of application GP and GPM vacuum pumps have been engineered for their application in the range of rough/deep vacuum. This vacuum pumps are fit for air/dry gases evacuation in the ranges : . 0.5 ÷ 20 mbar Abs. for GPM models . 10 ÷ 400 mbar Abs. for GP models

Warning The GP / GPM vacuum pump are not engineered for pumping aggressive, corrosive,poisoned, inflammable or explosive gases. These vacuum pumps cannot operate in explosive, inflammable or classified under this standard environments. In case of any doubt, contact GEV.


Beware GP and GPM cannot suct gases containing liquid or solid substances. All precations shall have to be taken in case of this situation. In case vacuum pump should run in dusty environment it is recommended to fix it with an additional filter, properly sized. In some applications, It is worthwhile to mount an oil-sump filter (GFOP) together with a cartridge filter in the following manner : . vacuum pump, oil-sump filter, cartridge filter - intake In case of any doubt, contact GEV A.3 Lubricants General Europe Vacuum recommends its special oil “TYPE G 880” to allow vacuum pump works properly If you use a non-approved oil, GEV cannot guarantee that the pumps will meet their operating specifications ( ultimate pressure, pumping speed, operating temperature etc. ) However the warranty is voided only if a non-approved oil adversely affects the operation and reliability of the pump. Use of others special grades lubricants for special applications is allowed after GEV approval. If a synthetic oil has been selected, GEV recommends its synthetic oil “TYPE SYG 880” Caution:don’t mix different oil into the pump. A specific procedure has to be applied to change standard oil by a synthetic oil. This specific procedure has to be done by GEV For any additional information and/or explanation please refer to our office .

A.4 Transport, lifting, manipulation and stock Pump is supplied complete with electric motor. Usually the pump is supplied without oil. Running without it would affect pump performances seriously. Fill up the vacuum pump before start up moving it always in the upright position. The slope angle must be minimized, otherwise the oil will pour out. Avoid any other orientation while moving pump. For pump lifting use the proper bands, balacing the weight properly, as per the side drawing, or equip vacuum pump with a hook screwing it inside the proper threaded hole.

Warning Check if pump leaks oil because there is slip danger . Use proper lifting equipment and make sure that all the safety norms have been observed.

Beware Untill the pump is put back in to service once more, it should be stored in a dry place , preferably at room temperature. Before taking the pump out of service, it should be properly disconnected from the vacuum system, purged with dry nitrogen and the oil should be renewed too. Both inlet and exhaust ports must be blanked off using the supplied seals . Gasballast valve must be closed and if pump has to be shelved for a long period of time, it is advisable to cover it with a plastic bag together with desiccant ( Silicagel ). If the pump has been shelved for over one year, standard maintenance must be effected and oil must be refreshed too before putting the pump into service again. Contact GEV again for any information.


B. Installation of the vacuum pumps GP/GPM B.1 Installation It is essential to observe the following instructions, step by step, to ensure a safe start up. Pump start up shall have to be carried out by skilled and trained personell. Pump must be installed on a flat and horizontal surface. Under the four antivibration feet, there are threaded holes for securing the pump. Beware The oil level cannot be read properly if the pump is tilted. Pump risks to run dry.The pump environmental temperature should be between 12°C. and 40° C. To ensure proper air cooling to the pump it is advisable to leave sufficient space to pump side being sure that the motor cooling side is free. Moreover check to leave enough space close to the pump allowing easy access to all the components, like : filter, oil level indicator, oil fill up and exhaust cap. B. 2 Connection to system The standard vacuum pump does not fit for being installed in explosion and hazard areas. Take contact with GEV if you are planning to install it in such areas. Before installing pump, or in case of maintenance, disconnect it from the electric mains to prevent the pump from running up suddently. Vacuum pump must be installed by skilled and trained personell. Take all safety precautions.


B.2.1 Suction side

Warning - Disconnect vacuum pump from mains when connected to suction piping. - Use flexible hoses either in suction and at discharge so that you can easily remove for making maintenance - It is worthwhile to foreseen in suction an insulating ball valve - The suction piping must at least have the same diameter of the pump connection . A smaller piping can reduce the pumping speed. It is advisable to apply Loctite or Teflon band to the threaded fittings for better tightness. -The maximum suction pressure must not exceed the the atmospheric pressure ( around 1013 mbar ).Do not run the pump with a suction pressure above this range. - Both raw material and seals used for piping assembling must comply with sucked gases nature. - If the sucked gas contains dust, it is absolutely necessary to equip vacuum pump a filter for dust additionally to the fine filter usually applied to pump suction inlet. - In the event of steams suction, it is advisable to contact GEV in advance. - No solid or liquid particles shall enter the pump. B.2.2 Exhaust side The vacuum pumps type GP and GPM are equipped in exhaust by one or more oil remover cartridges ( according to the pump size ) having a filtration in the range of 0,01 micron. When the oil remover cartridges are clogged, smokes in exhaust is visible, the pump temperature and the absorbed power gets increased and it may happen that the motor thermal protection switches on. It is advisable therefore to replace the oil remover cartridges as per the notice stated in the next pages. Check any particular case for assuring that the exhaust pipe is necessary or has been foreseen. The volatile substances can enter the oil remover cartridge. We recommend you to connect a discharge hose fit for any type of sucked gas. This is always necessary when the discharge gases are dangerous .


Warning Follow all the precautions when sucting process gases. The exhaust piping section must be at least like the pump exhaust hose . If the exhaust pipe is too small an overpressure in the pump can happen. Before installing exhaust piping check that the oil remover cartridge in exhaust are properly tight. They could be relaxed during transport or installation. A relaxed filter can create smoke in exhaust when running. It is advisable to install the exhaust piping with a syphon, for avoiding flushing back of condensate into the pump. If this is not possible, equipping pump with a condensate separator is recommended. If more than one pumps are connected to one exhaust line, provide a proper connector and a anti-suckback valve at each pump delivery.

Warning Do not run the pump with clogged or reduced exhaust piping. Before pump start up make sure that blind flanges or valves inside the exhaust piping are opened and that the exhaust piping is not clogged by foreign particles. The max exhaust pressure allowed must not be superior to 1.15 bar (absolute) The exhaust piping and the accessories must be properly sized for the max displacement, which is equal to the pumping speed of the pump same. Possible reductions to exhaust reduce pumping speed, increasing pump’s temperature and could overheat the motor or cause pump’s pressure increase damaging tightnesses or other internal components. If you are sucting dangerours gases, the exhaust piping must be tight.

Warning In case of installing the exhaust piping, check if vacuum pump is equipped by a silence rubber housed at delivery thread connection. If exhisting, disassemble the silence rubber and the screws, leaving the delivery free. After that, it is advisable to put the two metal nets again fixing them with screws, nut and washers. These operations avoid pump overpressure and the metal nets will prevent the pump from being entered by foreign particles thru the oiltank.


B. 3 ELECTRIC CONNECTIONS

Warning Check that electric main is off before connecting the junction box or in case you have to operate on it- The connection to main must be carried out by a skilled technician and according to the safety norms. Refer to the scheme underneath for connection. Connect the feeding cables to the junction box. The European standards declare to protect the electric motor with a proper device calibrated according to the datas shown on motor lable.

Warning If any motor or electric switch cuts the pump out. Re-start up of the pump can be carried out only manualy. After having carefully checked the stopping reason. Pump can start up also when suction is already under vacuum. After connecting motor and every time you alter the wiring, check motor rotation direction, check the arrow shown on motor lable.During check, suction must be open. If motor rotation is wrong, oil may be flushed back from the suction fitting (the vacuum system gets overpressed). Switch on the motor for a while for checking the situation . If the motor rotates contrarily to the correct direction, stops it immediately and inverte 2 phases of the electric connection to wiring. It is recommended to check the motor rotating sense with device fits for indicating phases sequences. A prolonged motor rotation in the wrong direction will damage the pump.


B.4 Pump start-up Pump must be filled up to the half of the oil sight glass. Always check that oil level & and motor rotation are correct before start up pump for the first time or before changing electric connections The pump can run to a temperature over 12° C.

Warning Before pump start up check that the connected components are both matching with the final application of the system Do not expose body parts to vacuum as this might cause injure. Do not run the pump with and reachable intake. Vacuum connections and fill-up/dreinage caps must not be opened during pump running. Any safety precautions should have to be taken for any specific application of the pump. This refers particularly to installation, functioning and maintenance and for the exhaust oils treatment and their transport.

Warning Do not put the hand on suction intake for checking the efficiency. Exposure to vacuum of a body part could lead blood concentration to the exposed part. B.5 Pump running

Warning Pump when running is hot and some parts could reach a surface temperature of 80°C. Burning risk in case of touching. Read carefully the warning printed on the red lable stickered to pump. B.5.1 Non condensable gas pumping If the process evacuates mainly non condensable gases, the vacuum pump model GP and GPM must be used with closed gasballast valve. If gases composition is unknown, and in case vacuum pump condesation cannot be excluded, it is advisable to run the pump with opened gasballast valve according to the information written in the next paragraph.


B.5.2 Condensable gas and steam pumping With the opened gasballast valve and right temperature, vacuum pumps GP and GPM can suck water steams up to the values written on each technical sheet. Gasballast can be opened with a tool. When it is opened, noise level of vacuum pump gets increased. Before evacuating steams, it is advisable to prewarm the pump for at least 30 minutes with closed suction and opened gasballast valve. Important Do not enter the pump with condensable steams untill it reaches the correct temperature. The gases sucked from process, when pump is cold, are condensating into the oil. In those processes where there is high percentage of condensable steams, suction must be opened quietly and only after reaching the correct pump temperature. Steams condensation in the pump is visible from oil-level increase during during pump operation as steams condensating are mixing with the oil. Traces of condensable steam changes oil property causing corrosion or low lubrication to pump Therefore, if steams have been sucked, pump must not be switched off soon after process because condensate mixed up with oil could cause alteration or corrosion. In order to prevent such problem, it is advisable to run the pump with the gasballast valve opened and the suction closed untill the oil is free from mixture. We recommend to let the pump run in this ways at least for 30 minutes after the process has been completed. Note During stop & go operation cycles, pump must never be disconnected it must run with the gasballast valve opened and closed suction ( whenever possible intercepted by valve ).Once that steams have been sucked away from process, ( for example during the final drying cycle ), the gasballast valve can be closed for improving the final vacuum. B.5.3 Operating in cycles in/out It is recommended to limit the pump start up to 5 / 6 times in one hour. Whenever requested from process, it is recommended to equip suction intake with an automatic valve fit for insulating and keep pump running continuosly. B.6 Pump stop GP and GPM vacuum pumps are equipped in suction by an anti-suckback valve closing the suction when vacuum pump is off keeping vacuum steady in all the connected appliances thus avoiding the flush back of oil into the appliance same. The valve does not compromize gasballast functioning. Therefore, under normal circumstances, pump stops after disconnection to mains. If the pump has sucted condensable steams, degas the oil leaving gasballast valve open as stated in the previous paragraph. If you have to stock pump longer, it is advisable to drain the oil and fil-up it again with a proper quantity of fresh oil. Close all the exhaust and suction inlets. It is not necessary to take special precautions or antirust oils.


Warning If vacuum pump has been disconnected due to the intervention of the thermalswitches or other safeties, pump has to cool up to environmental temperature and start up must be manualy carried out provided that stopping reason has been erased. For avoiding the sudden vacuum pump starts up it is recommended to start it again manually B. 7 Ultimate pressure in the pump If the values stated in the technical sheets have not been achieved during process, measure the ultimate pressure directly to pump suction inlet after its disconnection from system. After a long period of storing and after oil changement,it is advisable to wait for a while before pump reaches its max pressure. Infact vacuum pump must reach its functioning temperature while the oil is degassing. It is advisable to run the pump for the first time with gasballast valve open. The max pressure depends both from pump temperature and oil quality. The best max pressuire can be achieved wih a low pump temperature and using the recommended oils. B.8 Assembling of gasballast valve – Option Vacuum pumps type GP / GPM are supplied with or without gasballast. This gasballast can be assembled also afterwards .For choosing gasballast valve contact our manufacturer indicating pump type and serial no. C. MAINTENANCE

Warning Disconnect electric supply before disconnecting pump. It is important that pump does not start up

accidentally. If vacuum pump has sucked dangerous substances, check the nature risk and take the adequate

safety precautions. When sending back vacuum pump to manufacturer, it is advisable to indicate if pump is free from dangerous substances or contaminated. In that case, check nature risk. Pump must be properly packed so that it does not get damaged during transport and it does not

permit the pouring out of dangerous substances When wasting the exhaust oil , follow the environmental norms, any intervention must be skilled

personell Use only original spare parts

Maintenance or repairing being wrongly carried out or using unproper materials could damage the pump

Maintenance or repairing must be carried out by skilled technicians as an uncorrect intervention on pump could affect its lifetime and performances thus cancelling the warranty.

Do not use weared gaskets, use new one.


C.1 Maintenance schedule The maintenance schedule stated in the maintenance sheet underneath are approximate values for a normal function of the pump. Difficult environmental conditions and/or aggressive gases can increase significally the maintenance interventions.

CHECK AND MAINTENANCE FREQUENCY Oil level check Daily Oil conditions check Depending upon process First oil change After 100 : 150 running hours Subsequent oil change Refer to C.3 paragraph Oil filter replacement Every oil change Replacement of oil remover cartridge/s In case of oil mist in exhaust or yearly Replacement of coupling’ spider Yearly Net cleaning Monthly Check of anti-suckback valve Every 6 months Oil cooler cleaning Yearly ( just for models from 45 to 300 ) Replacement of filter – gasballast Every 6 months or according to final application C.2 Oil check C. 2.1 Oil level The oil casing has two oil sight glasses.: - at the bottom, where the oil must never go below - at the top, for normal check of oil status The oil status must always be in the middle of the oil sight glass If the pump has an oillevelswitch installed on it, fit for showing oil gauge, the oil level must cover completly upper sight glass. The test must be carried out when pump is stopped. Greater oil consumption shows that the exhaust elements are clogged The oil level must be checked over once a day as stated in chart.


C. 2.2 Oil condition Under normal conditions, oil looks transparent. If it gets black, must be changed. Final pressure is compromized, if gases or liquids are mixed into the oil It is possible to de-gas the oil by running the pump for about 30 mins. With closed suction and gasballast valve opened. C.3 Oil change Oil must be changed according to the following chart : VACUUM PUMPS MOD. GP – GPM 11 or 21 200 hours running Or every 1 / 2 months GP – GPM 45-65-100 500 hours running Or every 3 / 4 months GP – GPM 210 - 308 1000 hours running Or every 5 / 6 months Oil must be changed when pump is off but at exercize temperature.

WARNING Pump is hot when running, it is therefore necessary to use proper protections before acting on surfaces under hot temperature. Unscrew the oil drainage tap and let the oil flow into the proper tank carefully following the safety norms. When the oil flow decreases, screw the oil draining tap again, switch on the pump for a while ( 10 seconds max ) and then switch it off again. Unscrew the oil tap again and drain the oil left. Unscrew the oil filter. Take a new filter, damp gasket with oil and screw it on manually again. Close the oil draining tap. Unscrew the oil fill-up tap again and fill-up pump with fresh oil up to the bottom limit of the oil-glass level, switch on the pump shortly and then change the oil again following the above mentioned procedure. Do follow all the environmental instructions when wasting exhausted oil


C.4 Replacement of the oil remover cartridges at discharge When the oil remover cartridges in exhaust are clogged, this causes oil-mist in exhaust and an excessive oil consumption. Oil remover cartridges need to be immediately replaced. They must be replaced more often when subjected to oil-craking running at high-temperature and/or aggressive gases. . Take the cover away the oil-remover casing . Unscrew nut, pull out the oil remover cartridges and replace them During the dissassembling phase check that all the elements are correctly assembled. Beware Do not run the pump without the oil remover cartridges. These, infact, do produce a differential pressure inside the pump, fit for keeping the oil in circulation. It is however recommended to change the oil when replacing the oil remover cartridges. C.5 Cleaning of the dirt trap The net filter is housed at pump suction and it retains dust and solid particles. It must be kept cleaned so as to avoid the capacity reduction at pump suction. C.6 Checking the anti-suckbackvalve The anti-suckback valve is housed at pump suction. The valve must be kept cleaned thus assuring the proper pump running. If the pump sucts a certain quantity of dust and dirties, coming out from process, it is advisable to install a filter for dust on suction piping. For carrying out this operation, firstly disconnect suction piping. Then unloose the four screws housed in the upper part of the the pump body protective casing and the antivibration foot under the casing, polling out casing. Unloose the four screws and pull out suction fittings and the relative gasket. Remove the spring and the anti-suckback valve cleaning it. If this close rapidly, press spring gently Reassemble the suction fitting again Replace the old gasket with a new one. Beware The above mentioned operations fit for vacuum pumps GP or GPM up to 45 – 308 For the vacuum pumps models GP or GPM sizes 11 and 21 antisuck-back valve is not covered by casing. C.7 Replacement of the gasballast valve inlet filter If pump runs with the gasballast valve mostly opened , replace the filter every 6 months . On vacuum pump model GP and GPM 11 and 21 filter is visible. On the others vacuum pumps you need to disassemble the casing as stated in the previous paragraph


C.8 Check up of the floater valve ( only for vacuum pumps GPM up to 45 and 308 models )

WARNING This operation has to be carried out when pump is stopped and disconnected : If the pump pressure does not go below 5 mbar ( approx ) during running, check both that the floater valve is tight and the recycling piping. . Unscrew the 4 screws housed in the upper part of the pump body cover, unloose the foot under the casing and pull out cover definitively . Disassemble the recovery piping . Unscrew the 4 screws and pull out from chamber the valve group and the floater . Replace gasket . Clean the neck . Check the tightness of the floater valve on neck and eventually clean the rubber contact surface. . Check the gaskets and , whenever necessary, replace them with new ones. . Reassemble the floating valve again C.9 Cleaning or replacement of the oil recovery group (only for GPM 11 and 21 models)

WARNING The operation has to be carried out when pump is stopped and disconnected Check every 6 months the oil recovery group ( if the pumps runs under normal conditions )

- Unscrew oil recovery group checking that there is no oil inside the recovery chamber housed in

the upper part of the tank - Pull out the recovery group blowing it heavily with compressed air thru the holes for cleaning. - For reassembling it again do the operation inversely In case of oil leaking from the discharge ( oil recovery group fails ) replace the oil-recovery group completely It is however advisible to replace the oil recover yearly C.10 Disassembling & cleaning of pump discharge. - Pour out the oil - Unscrew the four fixing screws in the upper part of the pump body casing - Unloosen the pump foot in the lower part of the cover and pull out the cover itself - Disassemble the oil pipings - Unscrew the four or six nuts and take away the oil-remover tank - Take away the gasket - Anscrew screws and clean discharge part. - Reassemble them operating inversely


C. 11 Replacement of pump modul Pump’ moduls are referred to drawing number 207. This is valid for all the GP/GPM pump. For the spares parts do refer to the specific drawing for each vacuum pump model. We suggest to change all the modul gaskets (plane gaskets for oil case; oil piping system and for Gas ballast valve)with new ones. - Pour out the oil - Remove the body pump cover - Remove the inlet flange, the antisuck – back valve and the spring - Remove the gas ballast valve - Unscrew the nuts and take away the pump modul - Take away the coupling insert, unscrew the screws and remove the coupling - Take away the key. - Reassemble the pump modul operating inversely A clereance has to be kept between the half joints. Correct clereances are: PUMP MODEL CLEREANCE BETWEEN THE HALF JOINTS GP/GPM 11-21 2 MM. GP/GPM 45-65-100 2 MM. GP/GPM 210 3 MM. GP/GPM 308 4 MM.

E. TROUBLESHOOTING GUIDE

FAULTS CAUSES REMEDY Pump does not start or the thermal device starts after few

Motor is not properly connected The thermal device has not been properly adjuested The Volts do not fit with the motor’s one Pump is stucked

Connect motor correctly Readjust the thermal device Replace motor Replace pump

Pump does not start easily, vanes noise and higher power absorption

The rotating sense is uncorrect The oil temperature is too low, ( less then 12°C) Oil is too viscous Pump has been stopped since long time Oil remover cartridges are weared Exhaust piping is clogged

Change the rotation direction Heat the environment and the oil with a less viscousity one Use the correct oil Let pump run with closed suction untill hot Replace the oil remover cartridges Clean all the exhaust piping

Pump does not reach the stated Tag vacuum

Measuring instrument is damaged or unsuitable Leaking from both oil and suction pipings Anti-suckback valve on suction does not work properly Misfunctioning of the floating valve, of the oil recovery group or discharge bulkward Oil missing in the pump Shaft seals out of order or uncorrectly positioned Poor lubrication due to : . unsuitable or contaminated oil . oil filter clogged . oil pipings clogged Vacuum line is dirty Pump is too small

Check the measuring technique and the used instruments Check and tighten all fittings housed both on suction pipings and oil Check and repair the anti-suckback valve Check all the components Fill up pump with oil Replace the tight rings Change the oil and in case degass it Clean the oil lines Clean the vacuum line Check out the process details and in case replace the pump

Lower pumping speed

Suction net filter is clogged Oil remover cartridges are clogged Non return valve does not open easily Suction piping is not tight

Clean the net filter. Check if you need a proper anti-dust filter in suction Replace the oil remover cartridges Check and release the spring


FAULTS CAUSES REMEDY The pump is too hot

Cooling air is not enough Piping or fan is dirt Too high temperature of the gas aspired Insufficent oil quantity in the pump Oil recyrculation piping obstructed Oil filter is dirt Oil remover cartridge or discharge line are clogged

Place the pump in a more aired location Clean with air or solvent Verify the system and the reiability of the pump Restore oil level Verify and clean Replace oil filter Replace oil remover cartridges and verify the discharge

The pump leaks oil

Fittings and oil cyrculation piping are not tight or are spoiled Shaft seals too much used Oil remover cartridges are clogged

Verify the fittings, tight them, verify the pipings and eventually replace them Replace the seals Replace the cartridges

Oil in the system or in in the suction piping

Oil comes from the system The check valve is clogged or spoiled Oil level is too high

Verify the system to the process Verify the suction fitting Clean or repair the check valve Drain the oil excess

The pump has a huge consumption of oil Oil mist at the discharge

Oil remover cartridges are spoiled or out of their position Oil level is too high

Replace the cartridges and verify the correct placement in the oil remover Drain oil excess

Oil is dark Oil has been used for too many hours Oil is not the correct one Oil is burned by the too high temperature of the pump

Drain oil and replace it Replace oil filter and oil remover cartridges

Oil is turbid Condensation of water and mist sucted by the pump in the oil

Degas the oil opening the gas ballast or replacing the oil Verify if the process need a condensate trap at pump suction

The motor runs while the pump doesn’t

The coupling insert is broken

Verify and replace

The pump is stopped and the motor doesn’t start

The pump is without oil The blades are broken

Verify and fill-up Verify and replace the blades

Pump is excessively noisy

Oil level is very low or not visible Oil filter is clogged Coupling element is spoiled Large vacuum leak in the system

Add oil Replace the filter and the oil Verify and install a new coupling Repair vacuum leak

H . SAFETY INSTRUCTIONS FOR INSTALLATION IN HAZARDOUS AREAS Before to install rotary vane vacuum pumps type GP / GPM in potentially explosive areas, classified accordingly to ATEX Directive 94 / 9 / EC please read carefully these instructions.

Read carefully Operation and Maintenance Manual

Use only original spare parts Maintenance or repairing being wrongly carried out or using unproper materials could damage the pump causing risk to the people acting in ATEX enviroment

Verify vacuum pump is suitable to operate in the choose area, both for the external

environment and for the sucked gases and vapours. Area classification is customer responsibility.

Verify that electric motor, instruments and all the pump accessories are suitable for the area

Verify very carefully ATEX conformity of the following equipments: - Electric motor must be EEx and suitable for the gas group, category and temperature class

- The same for the coupling joint

It’s mandatory to install all instruments and accessories as specified in the risks analysis for the ATEX category and temperature class of installation

A thermal probe is mounted in the warmer part of the pump. Set point calibration must be at temperature below the temperature class of the area.

An oil level switch is mounted on the pump to avoid pump running without lubrication

Install the pump in a clean and dust free room. All the pump external surfaces will be clean periodically. Dust on hot surface must be carefully avoided.

Verify, every 6 months, the cooling fun integrity. No clearence must be in the joint points. Eventually change it.

Not more than 5-6 start up cycles per hour must be performed. If the process need an high number of start / stop cycles, install an isolation valve on the pump suction and leave the pump running continuously.

For any modification to pump running or performance parameters please contact us before

Is necessary to connect to earth the pump with a suitable cable. THESE SAFETY INSTRUCTION MUST BE OBSERVED CAREFULLY TOGETHER WITH THE OPERATION AND MAINTENANCE MANUAL OF ROTARY VANE VACUUM PUMPS TYPE GP / GPM
