Liquid Ring Vacuum Pump Design

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

Liquid ring vacuum pump design.

Liquid ring vacuum pumps are an economical and robust solution engineered to meet specific customer requirements. When a seal fluid other than water is used the liquid ring vacu um pump manufacturer will require the specific gravity specific. The klrc is a non pulsating vacuum. Find out how the nash liquid ring vacuum pump w.

A liquid ring pump is a rotating positive displacement pump. The design technology behind liquid ring vacuum pumps is advanced to achieve optimum reliable performance for the rigorous demands of harsh industrial environments. Many liquid ring vacuum pump manufacturers publish dry air curves with 60 f seal water figure 2. 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.

Kinney liquid ring vacuum pumps and systems. Nash liquid ring vacuum pumps are a reliable and durable solution for challenging process applications. 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 following figure shows construction of a typical cone type vacuum pump.

Cone type and flat plate type. 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. In this design the cells between the impeller rotor blades are open around the periphery. The impeller forces this sealing liquid to the periphery of the pump casing where it forms a moving ring of liquid.

Liquid ring vacuum pumps overview. From these curves correc tions are made to take into account actual operating conditions. Pump and motor only. Liquid ring vacuum pumps are designed in two different types.
