Understanding liquid ring vacuum pumps

NASH liquid ring vacuum pump is a reliable and durable solution for challenging process applications. When it was launched in 1905, our liquid ring vacuum pump was the first design and has been an industry leader ever since.
The working principle of a liquid ring pump is based on a circular pump body and an eccentric rotor: when the rotor rotates, the sealing liquid inside the pump forms a rotating liquid ring on the inner surface of the pump body, known as the "liquid ring".
Through persistent research and product development, we continuously introduce high-quality compressors and product upgrades, which perform well even under more demanding conditions while reducing total cost of ownership.
Do you need performance and proven reliability? You need Nash.
