In-house CNC machining and expert pump rebuild services — all under one roof in Tracy, California.
In-House Manufacturing
Our fully equipped machine shop allows us to fabricate and finish pump components in-house, right here in Tracy, CA. This means faster turnaround, tighter tolerances, and no dependency on outside suppliers for common parts.
From impellers and housings to shafts and wear rings, we machine components to exact specifications — whether replacing a worn part or producing a custom solution for a non-standard application.
Expert Rebuild Services
We service most major pump brands, and because many of their parts are cross-compatible with our own ARMS components, we can often repair your pump faster and at a lower cost than sending it to the original manufacturer.
Every repair starts with a full teardown and inspection. We identify worn or failed components, source or machine replacement parts, rebuild the pump, and verify performance before it goes back out the door.
Bring in your water truck by appointment
ARMS provides pump repair and service support for water trucks used in agricultural, industrial, and construction environments. Our team can remove the pump from your truck, fully disassemble it, perform all necessary repairs, and reassemble it to factory‑level performance.
Our in-house machining capabilities allow us to repair or fabricate many replacement components quickly, reducing downtime and helping you get your truck back into service faster.
