Liquid Ring vacuum pumps

Liquid Ring vacuum pumps

Liquid Ring vacuum pumps create the seal with the seal fluid being flung to the outside of the cylinder wall surrounding the rotor. This method of pumping air is fairly efficient, although it won’t achieve an extremely deep vacuum due to the seal fluids vapor point.

This type of pump can tolerate a far greater variation of inhalants than almost any other type of pump on the market; abrasive dust, water and many chemicals are easily passed through the liquid seal while doing no damage to the pump itself.  It is used commonly throughout industries for in-house vacuum systems.

Pneumotech has specified, designed, installed and repaired many of these pumps over the years.
