Characteristics Of Liquid Ring Vacuum Pumps

  • Accepts Carryover - Soft solids, moisture, slugs, chemicals, and more will not harm the pump but are washed out through the pump discharge.
  • Cool & Quiet Operation - The pump runs cool due to the circulation of the sealing water inside the pump.

  • Continuous Operation for Any Process - The pump can operate constantly and continuously at any vacuum level up to 1in. HgA.
  • Easy Maintenance and Longer Pump Life - Our pump only has one moving part so there is less wear and low maintenance requirements, making our pumps more affordable.
  • Environmentally Safe - Our pumps do not require oil changes, filters, oil-pans, condensers, etc. so operating facilities run clean and free of oil contamination and discharge.
