Oil Sealed High Vacuum Pumps

Oil Sealed High Vacuum Pumps

S Series

Minivac S Series pumps are oil immersed high vacuum pumps running on rotary vane technology. These are oil immersed rotary vane type vacuum pumps with a maximum vacuum of 0.05 mm Hg in single stage & 0.005 mm Hg in double stage. Material of construction is properly chosen from our own well-equipped foundry. All parts are precisely machined, micro finished and assembled to close tolerances for higher efficiency. The pumps come fitted with inbuilt gas ballast & an easy oil changing arrangement, Optional accessories like moisture trap, vacuum gauge with regulator, non-return valve, suction air filter, discharge oil mist filter can be provided.

Principle Working

An Oil Sealed rotary vane high vacuum pump consists of a housing, an eccentrically installed rotor, vanes that move under centrifugal and resilient forces, an inlet and an outlet valve. The inlet valve, if available acts as a vacuum safety valve that always remains open during the working of the pump. The working chamber is located inside the housing and is restricted by the stator, rotor and the vanes. The eccentrically installed rotor and vanes divide the working chamber into two separate compartments with variable volumes. As the rotor turns, gas flows into the enlarging suction chamber until it is sealed off by the second vane. The enclosed gas is then compressed until the outlet valve opens against atmospheric pressure. The outlet valve is oil-sealed. When the valve is open, a small amount of oil enters the suction chamber and not only lubricates it but also seals the vanes against the housing
