Pfeiffer Vacuum MVP 040 2 Diaphrahm Pump Overview:
The Pfeiffer Vacuum 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 pump units are directly connected to the drive motor.
The Pfeiffer Vacuum MVP 040-2 Vacuum Pump Offers the Following Features:
Robust and high-performance diaphragm pump with a pumping speed of up to 2.5 m3/h
For mains voltage: 90-126/180-254 V, 50/60 Hz
