Liquid Ring Vacuum PumpsSingle-Stage Liquid Ring Vacuum Pump
Single-stage liquid ring vacuum pump, 22 sizes: 2.7–440 m³/min, down to 33 mbar abs. Stainless, duplex, titanium and Hastelloy. For power, chemical, paper.

Compact cantilever liquid ring vacuum pump: 0.45–7.67 m³/min, 33 mbar abs., oil-free, anti-cavitation valve. For food, pharma, plastics and water works.
A small, oil-free liquid ring vacuum pump with a cantilever impeller: compact, easy to install and simple to maintain. It runs quietly without a silencer, uses little water and reaches 33 mbar absolute.
An anti-cavitation valve protects the pump during high-vacuum operation, and a flexible valve plate adjusts the discharge angle across the whole vacuum range. With an atmospheric air ejector even lower pressures are possible.
Oil-free operation keeps the process clean, and the mechanical seal (standard) reduces maintenance. The quality system is ISO 9001 certified.
We can supply the pump as a ready-to-use set with gas-liquid separator, heat exchanger and cavitation-protection piping.
Yes, it uses water (or another compatible liquid) as service liquid and needs no oil.
From 0.45 m³/min suction capacity.
Flow rate, head or vacuum level, the liquid or gas and its temperature, required materials, motor voltage and frequency, and any standard or ATEX zone. A data sheet or the nameplate of an existing pump is ideal.
