Liquid Ring Vacuum Pump

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 pump.

By the rotational movement of the impeller and the resulting centrifugal force the liquid within the cylinder forms the so called liquid ring. A liquid ring pump is a rotating positive displacement pump. 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. For more than 110 years nash liquid ring technology has provided reliable solutions for process applications.

As the bubble move from low pressure region to high pressure region the. Liquid ring vacuum pumps have six basic parts and can also be augmented with numerous accessories. As the shaft turns a liquid ring is created by the centrifugal force generated by the rotating impeller. Environmental pumps do not require an oil change filter oil pans.

The parts that comprise a liquid ring vacuum pump and perform its key functions are relatively simple. Basically between the inlet and discharge ports you have a rotary equipped inner. Liquid ring vacuum pumps and systems. 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.

In liquid ring vacuum pump the cavitation is occurs as a result of vaporization of the seal liquid. If the vacuum pump run at the vapor pressure region bubbles will form in the seal liquid. 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. 2be4 liquid ring vacuum pump.

The components of a liquid ring vacuum pump. Through our ongoing commitment to innovation product research and development nash continues to. This force holds the liquid ring against the. 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.

It is due to the vacuum pump operate at the vapor pressure region of seal liquid. Liquid ring vacuum pumps normally operate with water as the operating medium. Capacity ranging from 2 000 to 32 300 m h vacuum range. This benefits the user with less wear and simpler affordable maintenance.

The klrc is a non pulsating vacuum. Pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid.
