Rotary Piston Vacuum Pumps
Kinney KD and KDH Rotary Piston

KD and KDH vacuum pumps are belt-driven, low-speed rotary piston pumps. Since these pumps have no metal-to-metal contact from the clearances being filled with oil, these pumps are rugged and reliable; some have been in system operation for over 70 years.

Gas ballast and large oil capacity enable the KD / KDH models to handle moderate water or other vapor loads.

KD models are air-cooled, KDH models are water-cooled.

Applications:

 •Drying Chambers

•Degasifiers

•Filling Machinery

•Evacuation of Process Chambers

FEATURES

• Absolute pressures down to the low micron range
• Full pumping speed down to 1 Torr
• Long-life operation due to no metal-to-metal contact in the pumping chamber
• High resistance to abrasion and corrosion
• No small orifices to plug up
• Includes integral oil mist eliminator
• Adjustable gas ballast permits handling of condensable vapors
• Models KD30, KD50, KDH130, KDH150
