Precision CNC Machining for Pump & Valve Manufacturers
Pump and valve components demand leak-tight sealing surfaces, precise bore fits, and corrosion-resistant materials. A seat ring that's out of spec by 0.002 inches can cause a valve to leak under pressure. We machine ductile iron, 316 stainless steel, bronze, and Monel to tolerances as tight as ±0.0005 inches. Every order ships with CMM inspection reports, material certs, and pressure-boundary documentation.
Corrosion-Resistant Materials
We source and machine 316/316L stainless, duplex stainless, bronze C93200, Monel 400, and ductile iron — all with full material certs and heat lot traceability.
Seal-Surface Precision
We hold ±0.001" on bores and ±0.0005" on critical seat surfaces. Sealing faces are finished to 16 Ra or better. Every part is CMM verified before shipping.
Full Documentation
Dimensional inspection reports, material certs, pressure-boundary traceability — whatever your QA system requires for incoming inspection and compliance.
Parts for Pump & Valve Companies

4140 steel & bronzeServing the US Pump & Valve Industry
The US pump and valve market drives critical infrastructure — from water treatment and oil refining to chemical processing and power generation. Every system depends on precisely machined components that seal tight and resist corrosion.
Major OEMs and aftermarket suppliers rely on CNC machine shops that can hold tight bore tolerances on heavy castings, machine corrosion-resistant alloys, and deliver full material documentation for pressure-boundary compliance.
