Liquid Ring Vacuum Pump Design

Liquid ring vacuum pumps are designed in two different types.

Liquid ring vacuum pump design.

When a seal fluid other than water is used the liquid ring vacu um pump manufacturer will require the specific gravity specific. A liquid ring pump is a rotating positive displacement pump. Many liquid ring vacuum pump manufacturers publish dry air curves with 60 f seal water figure 2. Kinney liquid ring vacuum pumps and systems.

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. For more than 110 years nash liquid ring technology has provided reliable solutions for process applications. Cone type and flat plate type. The klrc is a non pulsating vacuum.

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. Pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid. Liquid ring vacuum pumps overview.

Close coupled motor mounted pumps. In this design the cells between the impeller rotor blades are open around the periphery. Nash liquid ring vacuum pumps are a reliable and durable solution for challenging process applications. The following figure shows construction of a typical cone type vacuum pump.

Pump and motor only. The impeller forces this sealing liquid to the periphery of the pump casing where it forms a moving ring of liquid. 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. From these curves correc tions are made to take into account actual operating conditions.

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