1.0 DESCRIPTION
1.01 Design and function
The G.E.V. GS series pumps are single stage, rotary vane vacuum pumps. Both models are equipped with
standard CE motors coupler directly to the pump by means of a flexible coupling. These vacuum pumps are
mainly utilized in the fields of handling, packing, packaging, woodworking and cardboard industries.
If the pump is particulate it is advisable to include a proper inlet filter with a replaceable cartridge (see start-
up point a). In case of gas steams saturation it is advisable to equip vacuum pumps with a condensate
collecting tank.
2.00 LIFTING AND TRANSPORT
2.01 Lifting and transport
The models 3-6-10 and 16 GS can be easily lifted. G.E.V. anyway reminds to final users to carefully follow
the given lifting instructions and to take all precautions, like gloves and forklift when carrying out such
operation

3.00 OPERATION
3.01 Installation
The pump must be installed on a level horizontal surface. It should also be installed in a n easily accessible
area for occasional maintenance or filter replacement. Insure that the area has sufficient air flow for the air
cooling circulation of the pump: this is very important to prevent the pump from overheating. Proper inlet
connections should be used to prevent leaks. Leaks will reduce the performance of the pump. Never restrict
the pump exhaust.
3.02 Electrical connections
Connect the motor’s cable to the winding box being careful to protect the motor with a suitable safety device
calibrating to the nominal current shown on the motor lab (pumps are not equipped with an own electric
switch as they are usually installed on a centralized plant)
G.E.V. vacuum pumps are supplied without electric cable. G.E.V. recommends to get this cable assembledby
a skilled technician as no liability for consequent misfunction can be taken

4.00 RISKS LIST
4.01 Mechanical risk
The presence inside the vacuum pump of detachable parts leades to the evaluation of the possible machanical
risks due to the parts same. For this reason, G.E.V. has equipped all their machines with protective casing
firmily screwed on pumps and fit for protecting the personnel dealing with the pumps. It is reccomended to
provide for skilled personnel.
4.02 Temperature risks
In those model where the ABS protective casing are missing, a lable is usually stickered on to prevent high
4.03 Acoustic risks
G.E.V. vacuum pumps have been designed and manufactured taking into consideration the acoustic risks’
standards presently in force in all CE countries.
5.00 START – UP
5.01 Check - up
Check that the motor is rotating in the correct direction; if the pump is installed in a dusty environment, it is
necessary to fit one or more additional filters. For some applications, it is advisable to equip vacuum pump
with an oil bath filter (GFOP) in line with a cartridged filter (GFMV or GFCV) as follows:

6.0 MAINTENANCE
6.01 Ordinary maintenance
Check if filter cartridges inside the pumps are full up and ,if necessary, clean it/them by means of
compressed air blown inside the cartridge. The same operations should have to be done in case of
additional filtering elements mounted in suction.
G.E.V. is not liable for operational failure due to mistakes during the assembling operation or the
utilization of non G.E.V. spare parts
6.02 Periodical maintenance
1500 hours Change filter cartridge. Refer to assembling scheme for removing the
cartridge
3000 hours Change blades in case their widths get reduced as follows:
GS 3 : 16,5 mm
GS 6 : 25.5 mm
GS 10 : 25.5 mm
GS 16 : 26 mm
GS 25 : 26 mm
GS 40 : 33 mm
GS 100 : 36 mm
This operation must be carried out by a skilled technician
G.E.V. is not liable for operational failure due to mistakes during the assembling operation or the
utilization of non G.E.V. spare parts
6.03 Trouble shooting
TROUBLE CAUSE REMEDY
Higt noise level Blades have worm out Replace blades
Motor bearing gets broken Replace bearing
Insufficient vacuum Blades have worm out Replace blades
Suction filter is dirty Clean or replace

7.0 INLET FILTERS
A comprehensive range of inlet filters is available to ensure efficient protection of all pumps from the
entry solid particles which cause internal pump damage resulting in perfomance degradation and
premature breakdown. There are two different types of filter :GFC (with paper cartridge) and GFM
(with metal cartridge)
