Liquid Ring Vacuum Pump

For more than 110 years nash liquid ring technology has provided reliable solutions for process applications.

Liquid ring vacuum pump.

As the shaft turns a liquid ring is created by the centrifugal force generated by the rotating impeller. 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. An eccentrically installed impeller rotates in the casing partly filled with liquid. Environmental pumps do not require an oil change filter oil pans.

The klrc is a non pulsating vacuum. 2be4 liquid ring vacuum pump. Nash liquid ring vacuum pumps are a reliable and durable solution for challenging process applications. Basically between the inlet and discharge ports you have a rotary equipped inner.

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. This force holds the liquid ring against the. It is due to the vacuum pump operate at the vapor pressure region of seal liquid. 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 parts that comprise a liquid ring vacuum pump and perform its key functions are relatively simple. Liquid ring vacuum pumps normally operate with water as the operating medium. 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.

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. Liquid ring vacuum pumps and systems. Capacity ranging from 2 000 to 32 300 m h vacuum range. 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.

By the rotational movement of the impeller and the resulting centrifugal force the liquid within the cylinder forms the so called liquid ring. If the vacuum pump run at the vapor pressure region bubbles will form in the seal liquid. As the bubble move from low pressure region to high pressure region the. This benefits the user with less wear and simpler affordable maintenance.

A liquid ring pump is a rotating positive displacement pump. In liquid ring vacuum pump the cavitation is occurs as a result of vaporization of the seal liquid.
