Keyway Machining Services for Pump and Valve Manufacturers
When your components control critical flow, pressure, or safety systems, the last thing you need is a loose or misaligned keyway.
At Keyseaters.com, we provide precision keyway machining for pump and valve manufacturers across the U.S.—with zero broaching required. Whether it’s a blind bore impeller hub or a hardened stainless shaft coupling, we deliver repeatable, spec-perfect keyways without the delays or overhead of broaching.
Why Valve and Pump OEMs Choose Keyseating
This industry demands:
High reliability – especially for pressure-rated systems
Exotic materials – like stainless, Inconel, and Monel
Low to medium volume – often custom or batch work
Tight tolerances – to avoid leaks, vibration, or failure
Keyseating is the ideal fit.
It allows us to machine internal keyways in blind bores, hard alloys, and complex part geometries with short lead times and no tooling cost.
