Oil Rotary Vacuum Pump
VD
アルバック
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.

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.

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.
