Our Principle
Liquid Ring Vacuum Pumps (LRVP) is the most used vacuum producing device in the industry. Integration of LRVP with Steam Jet Ejectors, commonly referred to as hybrid system, is one of the more efficient methods of producing process vacuum. The LRVP is a specific form of rotary positive-displacement pump utilizing liquid as the principle element in gas compression.
The compression is performed by a ring of liquid formed as a result of the relative eccentricity between the pumps casing and a rotating multi-bladed impeller. The eccentricity results in near complete filling then partial emptying of each rotor chamber during every revolution. The filling and emptying creates a piston action within each set of rotor of impeller blades.
The pumps components are positioned in such a manner as to admit gas when the rotor chamber is emptying the liquid, and then to allow the gas to discharge once compression is completed. Sealing areas between the inlet and discharge port are provided, to close the rotor areas, and to separate the inlet and discharge flows
