    VSN1501 / VSN2401 Oil Sealed rotary vacuum pump

      Features
      Compatible with continuous operation at high pressure (patent pending)
      A forced oil circulation system inside the pump enables stable operation even at high inlet pressures.When equipped with the optional oil mist trap and oil return mechanism, these heat-resistant pumps can run continuously at pressure equal to or below atmospheric pressure.

      Quiet-running performance
      The use of mechanism that reduces operating noise when pumping at ultimate pressure, allows noise levels to be reduced 74dB(characteristic A)for both the VSN1501 and VSN2401 models (Values measured at ultimate pressure while using an oil mist trap at a distance of 1 meter to the side of the pump).

      Low vibration
      The special single-stage vane design used in this pump permits the use of a high-speed motor (1500 rpm at 50 Hz) that helps to significantly reduce vibration levels in a low frequency range of the spectrum, where the transmission of vibrations through buildings can be a problem. This pump can largely eliminate the need for special foundation work and can be more easily installed on the upper floors of most buildings.

      Outstanding ease of maintenance
      Checking, adding, and changing oil are done at one side on the pump to facilitate greater ease in performance routine maintenance and inspection. Amount of time between oil additions is extended for oil capacity to be changed over a range of 8 to 1.5 liters.

      Applications
      ?  Evaporation, sputtering, and ion plating.
      ?  Gas substitution,back-filling and vacuum heat insulation.
      ?  Vacuum heat treatment furnaces, sintering furnaces,and brazing furnaces.
      ?  Vacuum drying, freeze drying, and vacuum degassing.
      ?  Automated leak testing, vacuum molding and vacuum casting.
      ?  Vacuum packing, vacuum adsorption, vacuum transport and others.

    VSN6501 / VSN7501 Oil Sealed rotary vacuum pump

      Features
      Low vibration
      The special vane structure used in this kind of pump helps to significantly reduce vibration in a low frequency which has high vibration conduction.

      Built-in oil mist filter
      Compact structure without the need for an external oil mist filter.

      Excellent drainage capacity
      Can be directly used with Roots pump, easy to connect.

      Effective air cooling while water cooling is optional
      In a non-open factory environment, water cooling can be used to save energy.

      Applications
      ?  Evaporation, sputtering, and ion plating.
      ?  Gas substitution,back-filling and vacuum heat insulation.
      ?  Vacuum heat treatment furnaces, sintering furnaces, and brazing furnaces.
      ?  Vacuum drying, freeze drying, and vacuum degassing.
      ?  Automated leak testing, vacuum molding and vacuum casting.
      ?  Vacuum packing, vacuum adsorption, vacuum transport and others.
