Elmo Rietschle 2BL "Pump in a Box" Package Liquid Ring Vacuum Pump


2BL Series

  • L-Series 2BL are recirculated, self contained, portable liquid ring vacuum systems. 

  • The 2BL 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 2BV liquid ring pump, an industrial electric motor, discharge separator, seal water cooler and discharge air cooler.

  • Split units
    The 2BL split range family of pumps allow the user to take advantage of the 2BL "Pump in a Box" 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.
