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.
Liquid ring vacuum pump systems.
A liquid ring pump is a rotating positive displacement pump.
They are typically used as a vacuum pump but can also be used as a gas compressor.
Pump and motor only.
Liquid ring vacuum pumps and systems.
Sliding friction is limited to the shaft seals.
Liquid ring vacuum pumps normally operate with water as the operating medium.
Close coupled motor mounted pumps.
By the rotational movement of the impeller and the resulting centrifugal force the liquid within the cylinder forms the so called liquid ring.
Available in cast iron for less aggressive applications and stainless steel for hostile applications and environments.
An eccentrically installed impeller rotates in the casing partly filled with liquid.
They are an inherently low friction design with the rotor being the only moving part.
Liquid ring vacuum pumps overview.
Nash medium capacity liquid ring vacuum pumps offer a highly powerful range of small to medium size single stage vacuum pumps for use in diverse industries including oil gas general industrial and chemical.
The klrc is a non pulsating vacuum.
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.
