Oil Rotary Vacuum Pump VD Series

Vacuum Pump

   VD series is a Double stage rotary vane type direct-driven oil rotary vacuum pump equipped withULVAC’s original multi-voltage motor.
This dual stage rotary vane mechanical vacuum achieves lower ultimate pressure.
   Design optimization and wide option realized quiet operation and so this pump is
suitable for a wide range of applications.

features

  • Multiple voltage motor fully developed by ULVAC

    A single motor can cover a wide range voltage, 200 to 240V / 380 to 460V.

  • Forced oil circulation system

    Pumping speed is stable even around atmospheric pressure. It is suitable for repeat and continuous running between atmospheric pressure and vacuum.

  • Various options are available for special application

    In addition to the standard model, we also offer models for special applications.

Applications

  • Evaporation, sputtering, and ion plating

  • Analytical instrument and leak test system

  • Gas exchange, liquid filling

  • Vacuum dry, freeze dry, vacuum deaeration, and vacuum insulation

  • Vacuum chuck and vacuum molding

  • Other vacuum equipments

Note) This specification uses SI measurement units. Conversion to non-SI units is as follows :
   6.7 Pa = 5 × 10-2 Torr
*1 Measured with a Pirani gauge.
  ( Apprx. 6.7 x 10-2 Pa when measured with a McLeod vacuum gauge. )
*2 VD90C is not allowed the continuous operation in the inlet pressure at 1,000 Pa or
   more and the maximum water vapor tolerance / maximum water vapor capacity
  (in the continuous operation)is 1,000 (Pa) / 600 (g/h).
*3 Factory shipment setup is 200V class Δ delta connection.
   Please change it to Y connection if working voltage is 400V class.
*4 High load operation means repeat pumping down between atmospheric pressure and
   vacuum in short term or long time operation at 10,000 Pa (75 Torr ) or higher.
