Oil Rotary Vacuum Pump VD-Series 901

Features

The move to improve work environments is creating a large demand for quieter vacuum pumps. Developed to meet this demand, the ULVAC Dual-Stage VD series oil rotary vacuum pumps use low-noise direct-coupled motors. Designed for easy maintenance, the VD series makes routine inspection and service extremely simple. The VD pump series can be used in a wide range of applications — from research labs (where quiet operation is very important) to production lines.

  • Optimized design achieved quiet-running
  • Easy maintenance
  • Forced oil circulation system ensures stable pumping speed below atmospheric pressure

 

Special Features / Further Applications

 

  • Evaporation, sputtering, ion plating
  • Analysis devices, leak test equipment
  • Gas substitution/supply, vacuum insulation
  • Vacuum drying, freeze-drying, vacuum degassing, vacuum packing, vacuum chuck, vacuum molding, etc.

Pumping speed 90 m3/h

Oil-sealed Rotary Vacuum Pump PVD Series

Features

  • Consistent Pumping Performance
    The pumping performance of the pump is extremely stable.
  • Low Vibration and Low Noise
    The pump is suitable for use in noise and vibration
    sensitive environments.
  • Easy Maintenance
    Because the pump body is machined from a single
    aluminum block casting the unit has fewer parts to maintain.
  • Gas-Ballast Valve
    Gas ballast valve is standard with these pumps to
    effectively deal with water vapor from condensation.
  • Oil-backflow Prevention
    This model contains an oil-backflow prevention device as
    standard equipment.
  • Various Options
    An optional base with casters allows ease of movement of
    the pump.

 

Special Features / Further Applications

 

  • Vacuum drying and freeze drying
  • Vacuum packing, vacuum adsorption and transport
  • Gas substitution, filling and vacuum heat insulation
  • Vacuum casting, etc.

Pumping speed 9 – 19 m3/h

Oil Rotary Vacuum Pump VS650A

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. Oil Rotary Vacuum Pump [VS650A / VS750A]

 

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.
  • Low vibration:
    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.
  • Easy maintenance:
    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:
    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.

 

Special Features / Further Applications

 

  • Evaporation, sputtering, ion plating
  • Vacuum drying, freeze drying, vacuum degassing
  • Leak test system
  • Gas exchange, filling, vacuum insulating
  • Heat treatment, melting furnace
  • Other various kinds of vacuum systems
