These liquid ring vacuum pumps are convincing – whether they are used for sterilizers
or for medical/laboratory equipment, they excel where extremely small suction capacities
are required within a minimum of space. With a suction volume of up to 11 m³/h, these
little workhorses are particularly quiet and consume very little water. It goes without
saying, of course, that the L-BV3 can also convey suction-side steam and liquids.
The L-BV3 features an unusually compact design: constructed in our tried-and-tested
modular design, it has extremely space-saving dimensions. And also in respect to
quality, the L-BV3 leaves no wishes unfulfilled: corrosion-resistant materials, reinforced
bearings and a stainless steel shaft in the pump section all consistently ensure
safe and efficient operation even under high loads.
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.
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.
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.
