Oil Rotary Vacuum Pump

VD Series

VD40C

アルバック

VD series is a direct-drive oil rotary pump with high efficiency (IE3) multi-voltage motor fully developed by ULVAC. This dual stage rotary vane mechanical vacuum achieves lower ultimate pressure. Design optimization realized quiet operation and so this pump is suitable for a wide range of applications.

Features

  • High efficiency (IE3) 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
    3 types, type A, B and H, are available in addition to standard type for special application.

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

*1 Measured with a Pirani gauge. (Apprx. 6.7X10-2Pa when measured with a McLeod vacuum gauge.)
*2 VD90C is not allowed the continuous operation in the inlet pressure at 1,000Pa or more. VD90C maximum water vapor tolerance / maximum water vapor capacity (in the continuous operation) : 1000Pa / 600g/h
*3 Increased safety explosion-resistant motor and pressure proof explosion-resistant motor are available as an option.
*4 Factory shipment setup is 200V class Δ delta connection. Please change it to Y connection if working voltage is 400V class.
*5 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.
