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.
Our new L-BV7 liquid ring pumps are high-powered and multitalented machines which
save space and up to 50 % in operating liquids. They can easily convey eight times
the quantity of liquid. The monoblock construction of the L-BV7/L-BV2 far surpasses
conventional modular pumps and is particularly suited for use in the plastics and
medical industries.
The robustness and reliability is unparalleled in operation. The machines are available
in various combinations of materials such as stainless steel, bronze, ceramic and
cast iron with ceramic coating. This enables them to be tailored to the respective
operating requirements and thus provides long-term resistance to erosion and corrosion.
The entire L-BV range shines with quality: reinforced stainless steel shafts in the
pump section and roller bearings with additional lubricant reservoir provide safe
and maintenance-free operation even under heavy loads.
