Oil rotary vacuum pump PKS Series

The PKS series models are extremely durable, large oil rotary vacuum pumps with very stable pumping characteristics. They are used in many applications, in areas ranging from the metal and automotive industries, to the chemical, pharmaceutical and food industries.

Features

  • The single-stage design of the rotary plunger vacuum pump is robust and very reliable.
  • High-grade cast iron is used, providing strength and resistance to abrasion.
  • Disassembly and reassembly for maintenance is quite simple. Exhaust valve inspection is also easy.
  •

Note:
This specification uses SI measurement units. Conversion to non-SI units is as follows :
Final pressure : 2.7 Pa = 2 x 10-2 torr; Water pressure: 0.3 MPa = 3 kg/cm2

*1 Measured by Pirani vacuum gauge (Approx. 1.5Pa when measured with a McLeod vacuum gauge)
*2 When ordering, specify whether you require a motor, and if you do, specify its type, voltage and frequency. Totally enclosed fan-cooled flange motors, increased safety flange motors, and explosion-proof flange motors are available as options.
*3 Other oil types are available. Contact ULVAC’s Sales Department.
