Industrial Pump Repair & Rebuilding
Centrifugal, positive displacement, sanitary and heavy-duty hydraulic pumps — rebuilt in our shop, tested, and backed by a 24-month warranty. When a big pump fails, rebuilding usually beats buying new.
Industrial pump repair & rebuilding, done right
When a production pump fails, the real cost is the line standing still. We rebuild industrial pumps of nearly every type in our Rialto, CA shop — and when a pump is a big, expensive unit, rebuilding it is usually far cheaper than buying new, with a shorter lead time than a replacement. We handle the full job: teardown, inspection, machining, new bearings, seals and wear parts, reassembly, testing and a 24-month warranty.
Heavy-Duty Pump Repair
Large process, mining and mill pumps where a rebuild beats a new purchase on cost and lead time. Full teardown, shaft and housing repair, and precision reassembly.

Sanitary pump repair →Pump types we repair
One shop, one warranty, one point of contact — for centrifugal and positive displacement pumps across every major design.
Centrifugal pumps
End-suction, split case and multistage centrifugal pumps for process, cooling water, boiler feed and transfer service. We repair impellers, shafts, wear rings, casings and bearing frames, and correct the vibration and cavitation damage that shortens pump life.
Positive displacement pumps
Rotary lobe, twin screw, progressive cavity, gear (internal and external), plunger and diaphragm pumps. These are precision machines — clearances matter, and we restore them to specification rather than patching them.
Rotary lobe & twin screw pumps
Gentle, low-shear pumping for viscous and shear-sensitive products, plus high-pressure twin-screw units for fuel, lube oil and process service. Rotor timing, lobe and screw clearances, and seal faces are all checked and reset.
Progressive cavity pumps
Rotor and stator replacement, drive-end rebuilds and seal upgrades for abrasive slurries, sludge and viscous fluids. We match stator elastomers to the product being pumped.
Gear pumps
Internal and external gear pumps for lubrication oil, fuel and hydraulic transfer. Housing bores, gear faces and shafts are measured and restored so the pump holds pressure without internal leakage.
High pressure & multistage pumps
High-pressure and multistage pumps for boiler feed, injection and washdown service. Staging, balance drums, thrust bearings and diffusers are inspected and rebuilt to hold rated head.
Vertical turbine & split case pumps
Vertical turbine pumps for deep wells, sumps and cooling water, and split case pumps for high-flow municipal and industrial service. Bowl, column, lineshaft and bearing work done in-house.
Slurry & chemical process pumps
Slurry pumps with hardened wear parts for abrasive service, and chemical process pumps in stainless and alloy construction. We repair or replace wetted parts to resist the product and the solids it carries.
Hydraulic piston, vane & variable displacement pumps
Axial and radial piston pumps, variable displacement pumps and vane pumps — the high-value heart of hydraulic systems. See our dedicated hydraulic pump page for Oilgear, Rexroth, Parker and other major brands.
Vacuum, boiler feed, cooling water & lubrication oil pumps
Vacuum pumps, boiler feed pumps, cooling water pumps and lube oil pumps that keep a whole plant running. We treat these as critical-equipment jobs, with testing before return.
When rebuilding beats buying new
On heavy-duty and high-value pumps — large centrifugal and multistage units, slurry and chemical process pumps, and hydraulic piston pumps — a rebuild typically costs a fraction of a new pump and gets you back in service faster than waiting on a factory lead time. A rebuild also keeps your existing piping, baseplate, motor and controls untouched, so there is no re-engineering. If a pump is truly beyond economic repair, we will tell you that plainly before any work starts.
- Full inspection first: teardown, cleaning, measurement and a written finding before we quote.
- Common failure causes fixed, not just the symptom: bearing failure, seal leakage, cavitation, shaft wear, misalignment and contamination.
- Parts and machining: bearings, mechanical seals, wear rings, shafts, impellers and housings repaired or replaced.
- Tested before it leaves: rotation, clearances and run checks so it goes back into service ready to work.
- Backed by a 24-month warranty on our rebuilds.
We also repair the equipment around the pump — see our hydraulic cylinder repair and gearbox repair pages, and our industries served. We have repair experience with major pump brands; see our brands page. Emergency breakdown? Visit emergency repair or call (714) 204-5167 any time.
How a rebuild works
Every pump or cylinder that comes into our Rialto, CA shop is disassembled, cleaned and inspected before we quote. We measure wear, check clearances against the manufacturer’s tolerances, identify the failed parts, and give you a straight answer: rebuild it, repair the failed section, or replace it. Turnaround depends on equipment condition, required parts, job complexity and availability. All rebuilds are backed by our 24-month warranty.
