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.
