Oil Rotary Vacuum Pump Model: PKS
ULVAC
For more information on ULVAC products, purchase, and/or consideration, click here.
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.
