Volume flow

90 to 600 m³/h
52.9 to 352.9 cfm



The block pumps in the L-BV5 family are characterised by a very high suction volume of up to 600 m³/h with suction pressures of up to 33 mbar abs. and are primarily used for applications with large quantities of liquids. The L-BV5 also simultaneously works as a condenser while suctioning  condensable steam. This enables the suction volume to be doubled. The sound pressure level remains under 73 dB(A) and therefore fulfils even the strictest noise stipulations.


The single-stage compact construction of the L-BV5 reduces the space required for the installation of the pumps to around half that required by conventional modular machines. The pump can be easily installed in extruding machines and chemical systems, even when mounted to the underside of the tables. When developing these liquid ring pumps, Elmo Rietschle placed the focus on robustness and reliability. The L-BV5 can provide up to 20,000 hours of continuous operation without requiring an interruption for maintenance, even under the harshest conditions. Reinforced stainless steel shafts, continuously lubricated bearings and a coated pump housing prevent wear and tear caused by solids that are also sucked in, and guarantee constant performance, even after many years of use.
