Oil Rotary Vacuum Pump VS650A/750A Series

The VS650A and VS750 are single stage oil rotary vane pumps. Design to provide low vibration and noise, the VS series eliminates the need for costly facility work. Both air cooled and water cooled models are available depending on customer installation requirements.

 

features

  • High displacement single stage oil rotary vane pump:

    Two models, 650m3/h and 750m3/h are available. Larger displacement can be obtained with combination of mechanical booster pump.

  • Design to provide low vibration and noise,

    The VS series eliminates the need for costly facility work. The pump can be installed on an upper floor.

  • Oil exchange cycle is longer due to a large oil tank (large oil capacity).

    Construction of oil tank is simple and easy to clean.

  • Integrated oil mist trap:

    Oil mist trap is inside oil tank. Cartridge type filter is easily replaced.

  • Air cooled and water cooled models are available depending on customer installation requirements.

    An oil cooler is used to reduce oil temperature increasing pump life.

Applications

  • Evaporation, sputtering, and ion plating

  • Leak test system

  • Heat treatment, melting furnace

  • Vacuum drying, freeze drying, vacuum degassing

  • Gas exchange, filling, vacuum insulating

  • Other various kinds of vacuum systems
