Simple Vacuum Pumps with Pressure Regulator, GEMP
Description
. Nozzle Ø : 1.2 ; 1.5 ; 2 ; 2.5 ; 3 mm
. 2 levels of vacuum : 60% - 85%
. Suction flow rate : up to 385 Nl/min

The GEMP series vacuum pumps are the simplest in the energy-saving range. They automatically regulate the supply pressure to an optimum pressure of 4 bar, thanks to an integrated pressure regulator, whatever the pressure in the compressed air network, and this without penalizing other applications which require more than 4 bar. GEMP pumps therefore reduce both energy consumption and the noise level.

They are available in:
. 5 flow rates (essential for evacuation time) characterized by the nozzle diameter (1.2 to 3mm)
. 2 different vacuum levels:
- Version 60% vacuum for porous products.
- Version 90% vacuum for airtight products.
For the same nozzle diameter, the suction flow rate increases proportionally to the decrease in the maximum vacuum level. As well as using with suction cups, they can also be used for applications such as dosing liquid, spraying and tank depressurization.
