Vacuum pumping stations
The Roots vacuum pumps of the GMa HV series complete with pressure relief valve (bypass) are mostly used together with our oil-lubricated vacuum pumps to accelerate evacuation times and to achieve a vacuum level of up to 0.01 mbar(abs).
The bypass valve allows the Roots vacuum pump to be started simultaneously with the rotary vane vacuum pump and protects the Roots vacuum pump from overpressure.
| Intake volume (m³/h) | 50-2840 |
| Final pressure (mbar) | 0,01 |
| Motor power (kW) | 1,5-11 |
