Close Coupled BVM Vacuum Pumps |
 Liquid Ring Service & Repair is now pleased to be able to offer a VERY economical alternative for other close-coupled pumps such as Nash, Travaini, Sihi, Dekker, Seimens, Corona, Robuschi, and many others. Our Standard pump is provided in cast iron/bronze construction, with mechanical seal as standard. All models can also be supplied in 316L Stainless Steel construction when there is a corrosive environment. Principals Of Operation: The working parts of the Liquid Ring vacuum pump/compressor consist of a multi-bladed rotor which is mounted eccentrically on the shaft in a round casing which is filled with water and air. As the rotor revolves and the liquid is thrown by centrifugal force to the outer most parts of the casing, it creates a water ring, which is concentric with the I.D. of the casing. Because of the eccentric placement of the rotor in relation to the casing and liquid ring, the spaces between the blades fill with air/gas at the inlet. This air/gas is then compressed by the liquid as it revolves to the compression point, which is then discharged and the cycle starts over again. The Liquid Ring vacuum pump/compressor is capable of handling small amounts of process carry over with out damage. The internal liquid fluid is not just the compressant responsible for the work, but cools the pump, and actually helps scrub impurities from the air/gas. |
