The diaphragm vacuum pumps of the series MVP 070-3 are three stage and those of the MVP 040-2 series are two stage, dry compressor vacuum pumps. The pumps are positive displacement pumps with a periodic change of size of the suction chamber produced by the movement of the diaphragm. The gas flow causes the valves to open and close automatically. The MVP 070-3 pump units are directly connected to the drive motor.
