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.

Energy-saving large liquid ring vacuum pump: 80–600 m³/min, 200–1013 mbar. Low impeller tip speed, SEBF coating, interchangeable with existing installations.
For the biggest vacuum duties – paper machines, ash handling, mining filtration – this large liquid ring pump combines high capacity with low energy consumption. Its optimised hydraulics and low impeller tip speed give quiet, stable, efficient operation.
Optimised flow passages raise efficiency significantly. A flexible discharge valve plate prevents over-compression, and closed-loop service liquid with a heat exchanger greatly reduces water consumption.
Flanged connections between body and side covers make the large pump rigid and vibration-resistant; horizontal disassembly is possible where space is tight. The impeller shroud ring is moved inward to stop deposits and reduce the effect of scaling.
Connections are compatible with the existing single-stage range, so it can replace older pumps without changing the pipework, and several parts are interchangeable. A partition can create two vacuum levels from one pump.
Yes, with a partition in the pump body one pump can serve two different vacuum levels.
Yes, the connections match the existing single-stage range, which reduces retrofit costs.
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.
