About liquid ring vacuum pumps
A liquid ring vacuum pump uses an offset impeller spinning in a casing partly filled with sealing liquid, usually water. The liquid forms a ring against the casing wall; the pockets between the blades grow on the inlet side to draw gas in and shrink on the discharge side to compress it. With no oil touching the gas, liquid ring pumps handle water vapor, condensable solvents and liquid carryover that would ruin an oil-sealed pump.
We carry single-stage, close-coupled liquid ring pumps from Dekker (Titan), Airtech (3AV), DVP (FLA) and Velocity Industrial (VLRV/NC), plus our own Vacuum Gurus 2BV Series, from 6 to 530 CFM.

Frequently asked questions
How does a liquid ring vacuum pump work?
An impeller mounted off-center in the casing spins a ring of sealing liquid against the casing wall. The space between each pair of blades expands on the inlet side, pulling gas in, then contracts on the discharge side, compressing the gas and pushing it out with some of the liquid.
When should I choose a liquid ring pump instead of a rotary vane?
Choose liquid ring when the gas stream is wet, saturated, or carries vapors, condensate or particles: sterilization, degassing, evaporation and distillation, vacuum drying, priming and extrusion. Oil-sealed rotary vane pumps reach deeper vacuum on clean, dry air but suffer when water or solvents emulsify the oil.
What vacuum level can a liquid ring pump reach?
The single-stage pumps on this page are rated to about 28 to 29 inHg. The vacuum you actually get depends on the sealing-liquid temperature: colder seal water gives deeper vacuum.
How much seal water does a liquid ring pump use?
It scales with pump size; the pumps here list roughly 0.75 to 11 GPM of service liquid. Partial or full recirculation can cut water use, and the Dekker Titan is designed to use about half the seal liquid of a conventional design.
