Ultimate pressure:
≤ 1 x 10-3 mbar
Pumping speed:
120÷324 m3/h
PHV 120 K, PHV 180 K and PHV 270 K are rotary vane two-stage, oil bath lubricated pumps.
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 120 K, PHV 180 K, PHV 270 K pumps are suitable for evacuating closed systems or operating at a constant vacuum of up to 1 x 10-3 mbar (absolute).
