L-BL2 in general
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.

Compact version

Also known as the Elmo Rietschle "pump in the box", these portable units are oil-free and air-cooled. They include an L-BV liquid ring pump, an industrial electric motor, discharge separator, seal water cooler and discharge air cooler.

Split units

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 offer 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 available.
