Soft solids, Moisture, slugs, Chemicals, etc, will not harm the pump. These impurities will simply be washed out through the pump discharge.
The pump runs cool owing to the circulation of the sealing water inside the pump. The operation is also relatively quiet - not exceeding 85 dBA
Our pumps can operate constantly and continuously at any
vacuum level – from 29” HG Vac. to atmospheric pressure.
NASH pump has few parts and only one moving part. Therefore wear is less and thus maintenance is simpler and cheaper.
Generally, a NASH pump has a longer life span, mainly due to its robust construction and because the NASH pump has only one moving part, the rotor, which is mounted on a shaft supported by a set of bearings designed for a B-10 service life of 20 years continuous operation.
The NASH pump does not require any oil-change, filters, oil-pans, condensers etc. Plant rooms run clean, free of oil contamination and oil discharge to sewers.

The working principle of a liquid ring pump is based around a 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. NASH liquid ring vacuum pumps feature three product sizes including small capacity, medium capacity, and large capacity liquid ring pumps.
