Ultimate pressure:
≤ 1 x 10-3 mbar
Pumping speed:
50÷90 m3/h
The flanged electric motor is coupled by an elastic coupling.
Cooling is achieved by forced air via a centrifugal fan.
An integrated check valve prevents the oil from coming back and the return of air into the chamber to be emptied during the stop phase.
An adjustable gas ballast prevents condensation inside the pump when small quantities of steam are sucked.
PHV 50 K and PHV 75 K pumps are suitable for evacuating closed systems or operating at a constant vacuum of up to 1 x 10-3 mbar (absolute).
