About Graymills

Welcome to Graymills
Graymills has 60 years of experience in moving and conditioning liquids! Whether it is for circulating machine tool coolants, cleaning in production, maintenance and service industries, or getting filtered, conditioned ink to its final destination, Graymills has the expertise to solve whatever you are up against.

Founded in 1939 as a pump manufacturer for machine tool coolants, we added parts cleaning equipment in 1944. In 1953 Graymills started working with the fledgling flexographic industry to create pumps, filters and accessories specifically for converters’ needs.

We invite you to browse through this site and learn about the products that have kept us strong. If you have any questions, feel free to contact us by e-mail, phone or fax. We value your input.
