Oil-lubricated rotary vane pumps GP/GPM
E range, Z series and oxygen version
The oil-lubricated rotary vane pumps of the E range are quiet, compact and easy to build into machines. The single-stage GP reaches 5 to 10 mbar, the two-stage GPM down to 0.1 mbar absolute.
Oil mist separator, oil filter, non-return valve and gas ballast are fitted as standard.
Pumping speed
11 to 300 m³/h
Ultimate pressure GPM
down to 0.1 mbar
Ultimate pressure GP
5 to 10 mbar
Cooling
Air
Features
- air-cooled, quiet and compact
- Oil mist separator, oil filter and non-return valve as standard
- Gas ballast against condensate
- higher pumping speeds (400 to 1,000 m³/h) on request
- Options: oil level and liquid monitors, inlet filter, vacuum control valve, temperature monitor
- also available in ATEX version
Application
Packaging, food, plastics processing and woodworking, conveying, laboratories and general industry.
With the Z series also where a lot of water vapour occurs, and with the O2 version for oxygen.
Z series for water vapour
The GPM Z series pumps (65 to 300 m³/h, 0.1 mbar) tolerate considerably more water vapour. The oil remains stable in quality and quantity, and condensate does not raise the oil level.

GP = single-stage (ultimate pressure 5 mbar), GP/M = two-stage (ultimate pressure 0.1 mbar) – both versions of each size are on the same data sheet.
Water vapour tolerance: maximum tolerable amount of water vapour with gas ballast.
Sound pressure level: average value without gas ballast.
Weight with oil filling.
Oxygen version O2
The GP/M O2 pumps are built with materials and synthetic oil for very high oxygen concentrations, for example for evacuating cylinders and systems or for food packaging. Available as GPM 45/65E, 100E, 160, 210K and 300E O2.

Pumping speed = nominal pumping speed; ultimate pressure as absolute pressure.
Sound pressure level: average without gas ballast.
Water vapour tolerance: maximum permissible amount of water vapour with gas ballast.
Standard voltage 230/400 V at 50 Hz, 460 V at 60 Hz.
Oil capacity with slash: min./max.
GPM 20E: motor power for single-phase / three-phase (data sheet ‘1-3’); standard voltage and ultimate pressure with gas ballast not stated.
Connections: pipe thread G (‘GAS’ in the original).
Dimensions: overall length, width and height from the dimensional drawings in the data sheets.
GP/GPM 11/21 and GP/GPM 300E are also available in ATEX versions (Directive 2014/34/EU).
Frequently asked questions
GP or GPM?
The single-stage GP reaches an ultimate pressure of 5 to 10 mbar and is sufficient for most packaging and conveying applications. The two-stage GPM goes down to 0.1 mbar, for example for drying and laboratory processes.
When to choose the Z series?
When a lot of water vapour is extracted. The Z series tolerates more vapour without the oil suffering or condensate raising the oil level.
Is the pump available for potentially explosive atmospheres?
Yes. GEV also supplies rotary vane, screw, claw and Roots pumps to ATEX Directive 2014/34/EU, tested by TÜV NORD. Tell us the zone and the medium, and we will determine the right version.
Who supplies and services the pumps?
We do. As General Europe Vacuum’s representative in Switzerland, we supply pumps and spare parts, advise on sizing and handle maintenance and repairs.

Which vacuum pump is right for you?
Pumping speed, ultimate pressure, medium and operating mode determine the choice. We size the pump with you, supply accessories and spare parts and take care of servicing.
