Oil Rotary Vacuum Pump

• 


• - Displacement speed(60Hz) : 100~650ℓ/min
• - Ultimate Pressure : 5 x 10-4 Torr

Oil rotary vacuum pump (Direct vane type vacuum pump:MS Series MS 1Stage and 2Stage) MS series type pump is oil rotary vacuum pump and designed to be used widely for all vacuum industries in both laboratory and industrial facilities. As shown in fig, this vacuum pump consists of pump body, including pump housing, rotor being eccentric in cylinder of motor oil case, the front and rear covers of cylinder, and parts related to it. This pump is bases on the principle that pump and motor are connected by flexible coupling, and than, even rotor of pump turns as motor turns. As rotor rotates, two vanes in groove of vane of rotor turn, making contact with the internal side of cylinder by centrifugal force. The gas thus drawn in through the intake port with dirt. Trap passes the open airing isolation valve and streams into the pump chamber. As vanes being rotated pass near the intake aperture, the gas in confined between two vane and then, turn toward exhaust valve. Passing exhaust valve, gas starts to be compressed, and the fully- opens exhaust valve and is exhausted through exhaust port. The inside and vane of cylinder, vane and vane of rotor and moving parts will be lubricates, and also, oil to be given to cylinder for security of seals.
