Rotating Equipment Repair Services — All Types, All Brands
One shop. Six service lines. Forty years of getting industrial rotating equipment back online — faster than the OEM, with a better warranty, and emergency service that actually answers the phone.
Kelsey Machine Services has been the go-to rotating equipment repair shop for industrial facilities, oilfield operations, and petrochemical plants across the country for over 40 years. We repair centrifuges, gearboxes, blowers, compressors, and mud pump fluid ends and power ends — all in-house, with our own machining capability, and backed by a written 24-month warranty. Our 24/7 emergency service is answered every day of the year.
What separates KMS from other rotating equipment repair companies is our fully integrated in-house capability. We don't subcontract the precision work — our own machine shop handles every bore, weld, and balance job under one roof in Stafford, Texas. That means tighter tolerances, faster turnaround, and a single point of accountability from teardown to test. Whether you need a centrifuge bowl and scroll rebuild, a parallel-shaft or planetary gearbox overhaul, a roots blower restoration, or a complete mud pump fluid end and power end rebuild, every job follows the same documented repair process and ships back to you with a full inspection report. We serve customers across all 50 states, Canada, and Mexico, and our free nationwide pickup and delivery means geography is never a barrier to getting the best repair available.
Industrial facilities, petrochemical plants, oilfield operators, and municipal water treatment facilities all depend on KMS because we understand that unplanned downtime is not an option. Our turnaround is fast, and our 24/7 emergency repair service — answered every day of the year including weekends and holidays — means a certified KMS specialist is always available when a critical piece of rotating equipment fails unexpectedly. If you are searching for the best companies for fluid end and power end repair services in the U.S., a certified rotating equipment repair specialist near you, or simply a shop that will stand behind its work with a written warranty, Kelsey Machine Services has the experience, the equipment, and the track record to back it up.
