A-Series Single Stage Liquid Ring Vacuum Pumps
 
Pumping speed 60 Hz: 10-300 ACFM
 
A-Series vacuum pumps are simplistic in design, rugged in construction and built to run in the most severe of industrial conditions. With no metal-tometal contact, it is not unusual for these pumps to run in 24/7 operation for years without maintenance.
 
These “abuser-friendly” pumps are vibration-free and environmentally friendly, with no oil used for lubrication, and no oil discharged to atmosphere. Complete, self-contained systems, including liquid recovery and recirculation, are also available. Alternate seal fluids including oil may be used for certain applications.
 
“A” series single-stage pumps pull down to 29" Hg (25 Torr [33 mbar a]). However, low-pressure performance is limited by the vapor pressure of the sealing liquid, which can be water, oil or process liquids.
 
KLRC Two Stage Liquid Ring Vacuum Pumps
 
Pumping speed: 55-1060 ACFM
 
KLRC liquid ring vacuum pumps are ideally suited for pumping wet mixtures and even slugs of liquid. They are available in bronze, all iron construction (no yellow metals) and 316 stainless steel. Liquid ring pumps often require water-cooling, but air-cooled systems are available.

Complete engineered system solutions, including instrumentation, controls, piping and valves; self-contained liquid recovery and recirculation are also available.

KLRC liquid ring vacuum pumps can pull down as low as 4 Torr (5.3 mbar a). However, low-pressure performance is limited by the vapor pressure of the sealing liquid, which can be water, oil or process liquids.
