From hermetically sealed pumps that eliminate leakage to engineered hybrid vacuum systems that optimize efficiency, we deliver smarter solutions custom-tailored to your specific requirements.

Liquid Ring Technology for the Chemical Industry

NASH & GARO liquid ring pumps & compressors use a fluid compressant instead of pistons, vanes, or rotating lobes. The liquid ring eliminates metal-to-metal contact and delivers cool running, low maintenance performance. While water is an excellent seal liquid and is often used due to its availability and convenience, we know it is not always compatible with chemical process applications.

In many chemical applications, trace amounts of water cannot be tolerated in the product, and in some applications, alternative seal liquids can yield process advantages. NASH vacuum pumps & compressors can operate with a variety of liquids including sulfuric acid, benzene, ethylene glycol, gasoline, and many more. Our experienced team of applications engineers can recommend a seal liquid that is compatible with your process gases.
