About Graymills | Industrial Parts Washers, Pumps & Inking Systems
Built for industrial performance since 1939
Graymills is a U.S. manufacturer of industrial parts washers, industrial pumps, and inking systems serving manufacturers, maintenance operations, pressrooms, OEMs, and distributors. Since 1939, we have focused on helping customers solve real production and maintenance problems with equipment designed for durability, application fit, and long service life.
We build solutions for demanding industrial environments, from manual, immersion, ultrasonic, and spray parts washers to centrifugal, diaphragm, gear, and high-pressure pumps, as well as inking and ink circulation systems for flexographic and gravure printing applications. Our product range is broad by design: customers come to Graymills when they need equipment that matches the job, not a one-size-fits-all recommendation.
Why customers choose Graymills
Application-first guidance
Selecting the right cleaning system, pump, or inking setup can be complex. Graymills is built around helping customers identify the right solution based on soils, fluids, viscosity, flow, pressure, parts, process, and operating conditions. That application-focused approach is central to how we sell and support our equipment.
A broad industrial product portfolio
Graymills offers a wide selection of equipment for cleaning, fluid handling, and pressroom performance. That includes parts washers for different cleaning actions and process requirements, pumps for a wide variety of industrial fluids and installation needs, and inking systems developed for the realities of pressroom operation.
Custom and OEM capability
In addition to standard products, Graymills develops custom systems and OEM solutions. The company supports standard or custom design, custom sheet metal, custom production schedules, and global engineering/application support, with UL/CSA certifications and CE/ATEX availability where needed.
Built to reduce risk
Graymills emphasizes proof before purchase where possible, including complimentary cleaning tests for qualifying applications and demo support in pressroom contexts. The goal is simple: help customers buy with more confidence and less risk.
