Single-stage liquid ring vacuum pumps

ZM Vakuum, Series ZLR-M (Black Line)

The following pumps were constructed for conveying (transferring) of air and gas.

The liquid ring vacuum pumps are used in chemical and pharmaceutical industry, food industry and textile industry for gas and steam extraction, evaporation and vacuum enrichment.

The pumps are very compact. This is reached by the fact that pump is put on directly on the engine flange and impeller is fastened on the engine wave.
