Liquid Ring Vacuum Pumps

Liquivac boasts an innovative liquid ring vacuum design and incorporates a twin start helical rotor mounted eccentrically in a cylindrical pump barrel.

On installation, the pump should be primed with a suitable liquid and during start-up, a liquid ring is created, forming a seal between the rotor and casing, creating a series of crescent-shaped cavities, travelling from suction to delivery. In the priming cycle, air is drawn into the cavities, compressed and discharged through the pump.

Once fully primed, the cavities are filled with liquid, displacing any liquid warmed in the priming cycle.

Liquivac’s cast iron or 316 stainless steel pump body, combined with a stainless steel rotating element, makes the pump extremely robust in operation.

Liquivac characteristics:

  • Discharge heads to 3 bar
  • Suction lifts to 8.5m
  • Long suction lines - 500m+
  • Priming rate to 40m3/HR
  • Flow rate - liquids to 35m3/HR
  • Can accommodate solids of up to 2mm in diameter

When used as a vacuum pump, service liquid is required from an external source. This does not have to be totally clean and the system can be arranged for recirculation.
