Oil Rotary Vacuum Pump

PKS Series

PKS

アルバック

The PKS series models are extremely durable, large oil rotary vacuum pumps with very stable pumping characteristics. High-grade cast iron is used, providing strength and resistance to abrasion. They are used in many applications, in areas ranging from the metal and automotive industries, to the chemical, pharmaceutical and food industries.

Features

  • Robust and long life. Low speed rotation with few sliding parts.
  • Excellent abrasion resistance material are used.
  • High efficiency multi voltage motor (IE-3) which enable to use 200-240 / 380-460 V.
    * Please select the voltage of solenoid for oil circulation.
    * For PKS-070B with 200V class, a single voltage motor will be recommended.
  • For PKS-070B, bigger oiler and oil level gauge are introduced. Inspection hole for V belt is added.
  • Vacuum heat treatment furnace, sintering furnace, carburizing furnace
  • Solvent exhaust
  • Vacuum impregnation, casting
  • Large chamber exhaust

*1 PKS-070B has been improved by changing the casting shape and adopting a large oil level gauge,
   a large capacity oiler,and a sealed belt cover with inspection view holes.
   There is no change in the mating dimensions and performance from the conventional model.
*2 Measured with a Pirani gauge. ( Apprx. 2.7 x 10-1 Pa when measured with a McLeod vacuum gauge. )
*3 Factory shipment setup is 200V class Δ delta connection. Please change it to Y connection if working
   voltage is 400V class.
*4 Other oil types are also available, please contact us.
