Liquid Ring Vacuum Pump Systems

By the rotational movement of the impeller and the resulting centrifugal force the liquid within the cylinder forms the so called liquid ring.

Liquid ring vacuum pump systems.

Available in cast iron for less aggressive applications and stainless steel for hostile applications and environments. Liquid ring vacuum pumps are rotating positive displacement machines providing process vacuum in industrial applications such as chemical electrical power environmental food beverage processing and packaging marine mining oil gas pharmaceutical pulp paper and textiles. Liquid ring vacuum pumps and systems. The klrc is a non pulsating vacuum.

Liquid ring vacuum pumps normally operate with water as the operating medium. An eccentrically installed impeller rotates in the casing partly filled with 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.

Liquid ring vacuum pumps utilize water or other processes compatible liquid as the sealant. A liquid ring pump is a rotating positive displacement pump. They are an inherently low friction design with the rotor being the only moving part. Pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid.

Sliding friction is limited to the shaft seals. 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 around a center void.
