  • Page 16: Switching Off The Pump

    Maintenance 6.4 Switching off the pump The pump can be switched off in any pressure range. Rotary vane pumps have an integrated safety valve on the intake side. If the differential pressure between the exhaust side and the intake side is ≥ 250 hPa, then the valve clos- es automatically and vents the pump when the pump is switched off.
