Water Ring Vacuum Pumps

Shenovac Engineers, an ISO 9001: 2008 certified company, offers a Water-Ring Vacuum Compressor (liquid ring) Pumps, which are rotating positive displacement pumps. These pumps are not only used as vacuum pumps but can also be used as compressors too. The pump compresses gas by rotating a vaned impeller, which is mounted eccentrically to the axis of the pump casing. Sealing water forms a moving cylindrical ring against the inside of the casing. This creates a series of seals between the impeller vanes and liquid ring. Gases drawn into the pump through an inlet port get trapped in the impeller cells, are compressed and goes to the next stage where they get compressed again, due to reduced volume caused by the rotation of the impeller, are discharged through exhaust port. Further, the process will allow the pump to automatically invent the quantity of liquid that will be discharged through exhaust port thereby removing the heat of compression from the pump. The main casing and almost all the components of the pumps are made from cast iron. However, to meet specific applications, the company can offer pumps and their components with special materials like SS-304, SS-316 and phosphor bronze on request. Shenovac water-ring vacuum compressor (liquid ring) pumps are available in single stage. The single stage pumps are much better choice if solvents are handled at higher vacuum level at 710 mm Hg subject to provision of the sealant water level is below 30°C and pressure at the site is 760 mm Hg. The technology in single stage water-ring vacuum compressor is designed to operate at vacuum levels up to 710 mm Hg.
