The PVD Series are belt-driven compact rotary vacuum pumps with outstanding evacuation characteristics. They are used by a large number of ULVAC customers.
- • Stable evacuation characteristics
Extremely stable evacuation performance
• Low noise Suited to noise-sensitive environments
• Simple maintenance and inspection Block configuration enables solid structure with few parts, making overhauls and other maintenance and inspection work easy and clear-cut.
• PVD-B Series Oil backflow prevention mechanism is provided as standard.

Note :This catalog 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.
*4 Other oil types are available. Contact ULVAC's Sales Department.
