Liquid Ring Vacuum Pump Design

The design technology behind liquid ring vacuum pumps is advanced to achieve optimum reliable performance for the rigorous demands of harsh industrial environments.

Liquid ring vacuum pump design.

For more than 110 years nash liquid ring technology has provided reliable solutions for process applications. Pump and motor only. Nash liquid ring vacuum pumps are a reliable and durable solution for challenging process applications. Liquid ring vacuum pumps are designed in two different types.

Liquid ring vacuum pumps overview. From these curves correc tions are made to take into account actual operating conditions. Many liquid ring vacuum pump manufacturers publish dry air curves with 60 f seal water figure 2. The following figure shows construction of a typical cone type vacuum pump.

Cone type and flat plate type. In this design the cells between the impeller rotor blades are open around the periphery. Pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid. A liquid ring pump is a rotating positive displacement pump.

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. The impeller forces this sealing liquid to the periphery of the pump casing where it forms a moving ring of liquid. The klrc is a non pulsating vacuum. Close coupled motor mounted pumps.

Find out how the nash liquid ring vacuum pump w. Kinney liquid ring vacuum pumps and systems. 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. 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.

Through our ongoing commitment to innovation product research and development nash continues to.
