 "KD and KDH Rotary Piston")
KD / 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.
