Low maintenance, high efficiency liquid ring vacuum pumps have many uses

Posted: Friday 14th August 2015

The wide range of liquid ring vacuum pumps available from EuroVacuum Products provide efficient liquid transfer with fit and forget levels of maintenance.

Liquid ring vacuum pumps work on a similar principle to a rotary vane compressor or rotary vane pump, so have only one moving part, the impeller, which is the basis of their reliable operation. Further enhancing their maintenance credentials, there is no seal to wear; instead a pressure seal is created by the pumped liquid as it is stirred into a vortex.

The low cost, low maintenance characteristics of liquid ring vacuum pumps makes them ideal for duties where operating cycles are long and continuous, where reliability is a must and unscheduled maintenance stoppages would be expensive in terms of lost production.

Typical uses include steam turbines, papermaking machines, groundwater management, vacuum distillation and vapour recovery. The pumps come in a range of sizes, from laboratory scale to those used in heavy industries and are available as single-stage or double-stage units. Three and more-stage units are also possible, although less common.

EuroVacuum Products supplies both single and double-stage pumps, the former producing vacuum pressures to 33mbar, and the latter to 0.5mbar. Both are available in monoblock, lantern and bare shaft versions and in a range of sizes.
