Liquid Ring Pumps
The general reliability of Liquid Ring vacuum pumps, low maintenance requirements, low vibration and noise levels coupled with their unique capabilities when handling wet gases all contribute to the popularity of the pump. Liquid Ring pumps are suitable for continuous operation on vacuum applications at any suction pressure down to 30 mbar. Standard performance data is based on 15° water as the seal liquid, lower pressures may be possible with alternative sealing liquid.
A wide range of capabilities are offered from two basic pumps configurations, single and two stages. The single stage is capable of operation at 30mbar A where required, but is most suited to applications with continuous operation at inlet pressures from atmospheric down to 100mbar A. The two stage range is most effective below 100mbar A.
