PVR HV BP roots vacuum pump
Roots vacuum pumps with bypass valve
Description
Roots vacuum pumps HV BP Series complete with bypass valve are mainly used coupled to a backing pump to speed up pumping down times and to achieve vacuum level up to 0.02 mbar abs. The bypass valve allows to start the Roots pump at the same time as the backing pump, protecting the Roots pump from any operation at high overpressure.
