Liquid Ring Vacuum Pump Diagram

A liquid ring pump is a rotating positive displacement pump.

Liquid ring vacuum pump diagram.

Liquid ring vacuum pumps and systems. Pumps that are about 50 hp and above are best placed on a con crete pad. As the shaft turns a liquid ring is created by the centrifugal force generated by the rotating impeller. This force holds the liquid ring against the.

Through our ongoing commitment to innovation product research and development nash continues to. Pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid. Nash liquid ring vacuum pumps are a reliable and durable solution for challenging process applications. Easy maintenance longer pump life liquid ring vacuum pumps are robust in construction and have only one moving part the rotor which is mounted on a shaft supported by a set of bearings designed for a long service life of continuous operation.

Our liquid ring vacuum pump design was the first of its kind at the turn of the 20th century and has been an industry leader ever since. The impeller forces this sealing liquid to the periphery of the pump casing where it forms a moving ring of liquid around a center void. The impeller 4 with the blades is located in the cylindrical housing 5. To produce vacuum in a two stage liquid ring vacuum pump a multi blade impeller on a shaft is positioned eccentrically in a cylindrical housing that is partially filled with sealing liquid.

As shown in above figure in a liquid ring vacuum pump the pumped gases vapors air is a mixture of gases are sucked via the inlet connection 3 into the pump motor unit and pushed out via the discharge connection 1. Nonetheless it is important to ensure that the pump s frame or baseplate is mounted level and firmly anchored. Step by step animation with an explanation of how the nash liquid ring vacuum pump works. This benefits the user with less wear and simpler affordable maintenance.

Environmental pumps do not require an oil change filter oil pans. They are typically used as a vacuum pump but can also be used as a gas compressor the function of a liquid ring pump is similar to a rotary vane pump with the difference being that the vanes are an integral part of the rotor and churn a rotating ring of liquid to form the compression chamber seal.
