PKS Series Oil Rotary Vacuum Pumps(1,600 to 7,000 l/min)
The PKS Series are large oil rotary vacuum pumps that are extremely solid and have stable evacuation characteristics. They are used in many applications, in areas ranging from the metal and automotive industries, to the chemical, pharmaceutical and food industries.
- • The single-stage design structure of the rotary plunger vacuum pump is solid and long-life.
• Made from high-grade cast metal, for outstanding abrasion and corrosion resistance
• Extremely easy to disassemble and assemble. Evacuation valve inspection is also easy.

Note: This catalog 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 (about 6.7 x 10-1 Pa with MacLeod 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.
