Oil rotary vacuum pump PVD Series
The PVD series are belt-driven compact rotary vacuum pumps with outstanding evacuation characteristics. They are used by a large number of ULVAC customers.
Features
- Consistent pumping performance
- Low vibration and low noise
- Because the pump body is machined from a single aluminum block casting the unit has fewer parts to maintain.
- Oil-backflow prevention(PVD-B series)

Note:
This specification uses SI measurement units. Conversion to non-SI units is as follows
Final pressure : 6.7 x 10-1 Pa = 5 x 10-3 torr
*1 PVD-B series models : PVD-180B and PVD-360B are versions of PVD-180 and PVD-360 with oil backflow prevention mechanisms.
*2 Measured by pirani vacuum gauge (about 6.7 x 10-2 Pa with macLeod vacuum gauge)
*3 When ordering, specify whether you require a motor, and if you do, specify its type, voltage and frequency. Totally enclosed fan-cooled motors, increased safety motors, and explosion-proof motors are available as options. (Except PVD-B series)
*4 Other oil types are available. Contact ULVAC’s Sales Department.
