Liquid Ring Pump

The Nuphlo Liquid Ring pump (LR250) is an innovative hygienic pump with well proven features conferring good self priming and suction capability. The close tolerance impeller guarantees rapid pick-up when pumping intermittent flows or aerated frothy products.

There is presently one size Nuphlo Liquid Ring Pump which has a 4” (100mm) inlet and 3” (75mm) discharge.




  • Where self priming is required, frothy products or intermittent flows are encountered, a liquid ring pump is the best choice.
  • Maximum flow capacity 50m3/hr.
  • Once the chamber has an initial charge of liquid, the liquid ring pump
    will always lift (up to five metres negative head) even with an empty suction line.
