NASH liquid ring vacuum pumps are the reliable and durable solution for challenging process applications. Our liquid ring vacuum pump design was the first-of-its-kind when it was launched in 1905, and has been an industry leader ever since.
The working principle of a liquid ring pump is based on a round pump body and an eccentric rotor: As the rotor spins, the seal liquid inside the pump forms a rotating liquid ring on the inner surface of the body, forming the “liquid ring.”
Through an ongoing commitment to research and product development, we continue to introduce quality compressors and product upgrades that excel under the most demanding conditions, while reducing the total cost of ownership.
Need performance plus proven reliability? You need Nash.
