SWAM Rotary Vane Vacuum Pump is an oil-sealed
rotary displacement pump. The pumping system consists of a housing , an
eccentrically installed rotor , vanes
that move radially under centrifugal and resilient forces and the inlet
and outlet . The inlet valve, if available, is designed as a vacuum safety
valve that is always open during operation. 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 and displaces process vapors to atmosphere
