 A liquid-ring pump is a rotating positive-displacement pump 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. They are an inherently low-friction design, with the rotor being the only moving part. Sliding friction is limited to the shaft seals

This type of pump is great for situations where priming can be an issue, there is however a trade of as the disruptive action of the impeller can increase noise in the system

The earliest liquid-ring pumps date from 1903, and for liquid-ring vacuum pumps and compressors in 1914
