Liquid Ring Vacuum Pumps
L-Series Liquid Ring Vacuum Pumps
Vacuum pumps L-BV2
Volume flow
27 to 145 m³/hr
15.9 to 85.3 cfm
The monoblock construction is particularly suited for use in the plastics and medical industries.
Robust and reliable.
Available in various combinations of materials such as stainless steel, bronze, ceramic and cast iron with
ceramic coating.
Long lasting due to ceramic coating.
Can be customized.
Long-term resistance to erosion and corrosion.
Reinforced stainless steel shafts in the pump section.
Roller bearings with additional lubricant reservoir provide safe and maintenance-free operation even under
heavy loads.
IE3 / Nema Premium on request.
Vacuum pumps L-BV5
Volume flow
90 to 600 m³/hr
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.
Vacuum pumps L-BV7
Volume flow
27 to 145 m³/hr
15.9 to 85.3 cfm
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 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-BV7 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.
Vacuum pumps L-BL2
Volume flow
27 to 1200 m³/hr
15.9 to 705.9 cfm
The L-BL2 range comprises compact plug-and-play systems for easy on-site installation. The pumps are air-
cooled, 100 % oil-free and do not require additional water during operation. In addition, the vacuum pumps
provide a much higher resistance to water and steam than alternative systems. Thanks to contact-free
compression, they are virtually wear-free in operation and need no periodic maintenance. The patented
discharge-air cooling system ensures that the pumps will not heat up by more than 15 K above room
temperature. The pumps work reliably in continuous operation and are steam resistant and insensitive to
condensation of the pumped air.
Pump units
Vacuum power units of the L-BL2 Split type are standardised liquid ring pump circulation systems with patented
exhaust air cooling for large volume flows. A considerable amount of the water contained in the cool exhaust air
condenses, remains in the system, and is thus available as operating water. As a result many applications no
longer require additional operating water. Our low-maintenance vacuum pumps have been tried and tested for
many years in numerous industrial applications. A comprehensive product range of accessories is available for
this pump type.
Split
The L-BL2 split range family of pumps allow the user to take advantage of the L-BL technology in applications
where higher air volume is needed or for special process requirements. They are suitable for applications
involving aggressive suction materials and can also be implemented e.g. in the food & beverages industry
where they are available in versions made entirely of stainless steel. We also sell versions equipped with all the
valves including tubing required for integration into a CIP cleaning process. Air-to-water heat exchangers or
plate heat exchangers are also on offer.
