KWP liquid ring pump


As early as the mid Eighties, KAISER developed the first water ring pump in a light construction for mobile applycation. In the KWP housing, an eccentric rotor produces a ring of water using centrifugal power. Volume changes in the rotor chambers assure that air is sucked in and compressed. This construction type features high resistance to dirt particles and is ideally suited to vacuuming wet and dry mediums. The contact-free rotor assures extremely quiet running and a long life cycle. The KWP causes no contamination of the pump exhaust air by lubricants and oils. The oil-bath bearings require no maintenance.

Lightweight and reliable

The light construction increases the vehicle’s useful load. The integrated Intercooler System assures a consistently low temperature budget for the service water. Even in the case of high exterior temperatures, continuous operation is possible and even extended vacuuming jobs in the end vacuum range result in no overheating of the KWP.
