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.

Single-stage double-acting water ring vacuum pump: 9–146 m³/min, 80–1013 mbar, radial inlet/outlet, no metal contact. Safe for flammable and explosive gases.
A proven double-acting water ring vacuum pump for gases that contain no solid particles and are insoluble or slightly soluble in water. Near-isothermal compression makes it especially suitable for flammable and explosive gases.
There is no mechanical contact between impeller and casing, so there is no wear. A defined gap between impeller and distributor makes the pump insensitive to dust and small particles. It can run continuously for long periods.
Direct coupling, belt drive or gearbox drive are possible, and the pump body and feet can be dismantled horizontally. Each size has a matching atmospheric ejector to increase the vacuum.
Condenser vacuum and ash removal in power plants, vacuum distillation, crystallisation and deoxygenation in oil and petrochemicals, pharmaceutical vacuum, paper machines, plastics forming, mining flotation and coal-seam gas, tobacco, PSA units and food packaging.
Yes, compression in the water ring is nearly isothermal, which keeps gas temperatures low.
9 to 146 m³/min.
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.
