Austin, TX · Industrial Pump Repair
Industrial pump repair in Austin, TX
A failed industrial pump almost always raises a second question about the motor driving it, which is why it helps to have pump repair and motor repair in the same shop. Lopez Electric Motor Works provides industrial pump repair for Austin plants, water and wastewater systems, and building mechanical rooms. We inspect, repair, and rebuild industrial and commercial pumps to restore reliable flow and get the unit back in service quickly.
The Lopez family has run this business since 1972, and in 2026 the shop is still in San Antonio, with Austin and Central Texas inside our service area. Austin customers call 512-788-4594 to reach the team directly. Because we also repair the motor that drives it, a pump and its motor can come in together and be checked as a set, which saves a second trip and a second wait.
Pump problems we take on
Our pump work is for industrial and commercial equipment, the pumps that move water, wastewater, process fluids, and chilled or heating water through a facility. In centrifugal pumps, the most common design, the wear parts are predictable: seals, bearings, impellers, wear rings, and shaft sleeves. The failures that bring a pump in usually trace back to one of these:
Seal leaks, often after the pump has run dry or handled abrasive solids.
Bearing failure from contamination, lost lubrication, or misalignment between pump and motor.
Cavitation, which pits the impeller and sounds like gravel rattling through the casing.
Impeller and wear ring erosion that cuts flow and pressure while the pump keeps running.
Vibration from imbalance, a bent shaft, or a loose base.
Overheating or seizing after the pump has run against a closed valve or without enough flow.
A pump that keeps failing the same way is often running far from the operating point it was selected for, or it’s starved on the suction side. We’ll look for that cause along with the worn parts, because a new seal on a pump that’s still cavitating only buys time.
Inside a pump rebuild
The steps are the same whether the pump came off a cooling tower loop or a lift station:
Intake.
Teardown and inspection.
Report and quote.
Rebuild.
Motor check and return.
Follow-up.
How long a pump rebuild takes
24-hour turnaround is our specialty, and a pump repair can move that fast when the parts are on hand. Larger pumps, unusual materials, or parts that have to be ordered take longer, and the quote will tell you which situation you’re in. If the pump serves a system that can’t wait, 24-hour emergency service is available, and our field crew can diagnose it in place before you pull anything.
Is a rebuild or a new pump the better call?
A rebuild is usually the better value when the casing is sound, the pump is the right size for the job, and the failure was in wear parts, since it avoids changes to piping and mounting. Replacement makes more sense when the casing is cracked or badly eroded, when parts are no longer made, or when the pump has been mismatched to the system since the day it went in. A rebuild won’t fix a pump that was the wrong choice for its duty, and in that case we’ll say so and help you source a better-matched pump.
Controls are part of the decision too. A pump that short-cycles or runs against a closed valve wears out faster, and a new level controller or a variable frequency drive can stretch the life of a rebuilt pump. We design pump controls built around your system when the old controls are part of the problem. On chilled and heating water loops, pump staging and speed usually come from the controls that run the building, and we work on that side as well.
Information that speeds up a pump quote
Some of these you’ll know off the top of your head, and some may take a walk to the pump. Any of them helps:
- The data plate, with manufacturer, model, serial number, and size.
- The fluid it moves, its temperature, and whether it carries solids or chemicals.
- The flow and pressure it’s supposed to deliver, if you know them.
- What changed, such as a leak, new noise, vibration, low flow, or a tripping motor.
- The motor’s nameplate, and whether the pump runs on a VFD or a fixed-speed starter.
- Whether the pump is still installed and where it is in the Austin area.

Pump repair questions from Austin facilities
How long does it take to rebuild a pump?
A straightforward rebuild with parts on hand can be turned around quickly, and 24-hour turnaround is our specialty. Rebuilds that need ordered parts, machining, or special materials take longer. Lopez Electric Motor Works gives you the expected time with the quote, so you can plan the outage.
What causes an industrial pump to fail?
Most failures show up in the seals and bearings, and those usually fail because of something in the system. Running dry, cavitation from poor suction conditions, misalignment with the motor, contamination, and operating far from the design point are the common causes. Fixing the cause along with the parts keeps a rebuilt pump from coming back.
Do plumbers fix industrial pumps?
Plumbers handle building plumbing and many smaller pumps in it. Industrial process pumps, large circulating pumps, and pumps that come out with their motors are usually repaired by a pump and motor shop that can tear them down, replace wear parts, and test the motor in the same place.
Can you repair the motor at the same time?
Yes. Motor repair is where the business started in 1972. Send the motor with the pump and it will be tested and repaired in the same shop, so both come back ready to run together.
