Two-stage oil-flooded rotary vane vacuum pumps of the PHV series were developed to achieve higher vacuum capacities. Installation, operation and maintenance have been simplified. The pumps were developed for the laboratory use. Fields of application in the semiconductor industry, X-ray tubes, measuring instruments, light bulbs, fluorescent lighting, distillation, cooling devices, cold dryers, mass spectrometers are known.

The pumps are equipped with an oil check valve, gas ballast valve and ISO KF clamps. Pump and motor are connected by an elastic coupling.
