These single stage oil sealed rotary vane pumps use 3 vanes that are eccentrically mounted in a rotor and uses centrifugal action to maintain vane contact with the stator walls as it rotates thus creating vacuum.   The air is compressed from the intake port and released through the exhaust port.  The pumps come with an exhaust filter and gas ballast valve for purging condensable vapors.  They also employ an anti-suck back valve so that oil does not enter the space being evacuated upon power outage or by turning off the pump with the system under vacuum.  There are 2 models for each pump one series can reach 20 Torr pressures the other (H) series employ an oil re-circulating system to allowing them to reach pressures of 2 Torr.  Electrical configurations are variable based on customer demand.  Standard motor is 230/460 3 Phase  60 Hz.  Explosion proof and European frequencies are available.  

Features

• Environmentally friendly  

• Oil mist eliminator

• Low noise levels

• Oil return check valve

• Anti-Suck back valve 

• Gas ballast valve

These pumps compete directly with pumps historically produced by either Becker or Busch vacuum.  They perform in the same manner, reach the same pressures, just cost less.  If you are looking for a good pump, at a good price give us the chance to quote.
