Liquid Ring Pumps Single-Stage Plate
Liquid ring vacuum pumps are positive displacement pumps that use a ring of liquid to create a seal between the vanes or impeller and the pump housing, creating a vacuum and pumping gas or vapor out of a chamber. They are rugged, reliable and widely used in applications ranging from chemical processing, paper and pulp industry, power generation, and wastewater treatment. They excel at handling condensable vapors and liquid slugs, making them ideal for wet applications with high levels of contamination.
