Page 34: Operation With Flushing Gas
4. Open the shut-off valve on the vacuum flange. Interrupting/stopping the flushing gas supply To degas the operating fluid effectively, Pfeiffer Vacuum recommends that you shut off the pump on the intake side following process end, and continue operation for around an hour at ultimate pressure with the flushing device switched on. -
Page 35: Switching Off The Pump
You can switch off the pump in each pressure range. Pfeiffer Vacuum rotary vane pumps have an integrated safety valve on the intake side. The safety valve automatically closes from a differential pressure of ≥250 hPa between the exhaust and intake sides, when the pump is switched on, and vents the pump. -
