Technical Specifications

Technical specifications
Liquid ring pumps operate with only one moving part, the impeller shaft assembly. The impeller is mounted eccentrically relative to it’s casing. The liquid ring is formed by the service liquid (normally water) rotating concentrically in it’s casing. Process gas enters through the suction port, travels between the impeller blades and is compressed prior to exhausting through the discharge port along with a quantity of service liquid.
