Liquid Ring Vacuum Pump Design

Close coupled motor mounted pumps.

Liquid ring vacuum pump design.

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. The most common liquid is water these are sometimes called water ring vacuum pumps but these can be created to work with any liquid type. Through our ongoing commitment to innovation product research and development nash continues to. The design technology behind liquid ring vacuum pumps is advanced to achieve optimum reliable performance for the rigorous demands of harsh industrial environments.

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 portion of the discharge gas that is not discharged out of the pump but leaks past the seal clearance between the vane of the rotor and seal segment of the cone is called vaneslip. Nash liquid ring vacuum pumps are a reliable and durable solution for challenging process applications. In this design the cells between the impeller rotor blades are open around the periphery.

Liquid ring vacuum pumps overview. Pump and motor only. Many liquid ring vacuum pump manufacturers publish dry air curves with 60 f seal water figure 2. When a seal fluid other than water is used the liquid ring vacu um pump manufacturer will require the specific gravity specific.

Liquid ring vacuum pumps are designed in two different types. From these curves correc tions are made to take into account actual operating conditions. Find out how the nash liquid ring vacuum pump w. The klrc is a non pulsating vacuum.

A liquid ring pump is a rotating positive displacement pump. Pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid. Kinney liquid ring vacuum pumps and systems. The following figure shows construction of a typical cone type vacuum pump.

Cone type and flat plate type.
