Industrial Pump Rebuild Servicesin Northwest Indiana
Quick overview
A pump rebuild is a complete overhaul of an industrial pump, including teardown, inspection and replacement or repair of the impeller, wear rings, mechanical seal, bearings and shaft. SSI rebuilds pumps in our Portage, Indiana shop, then reinstalls and laser aligns them so the new seal and bearings last.
What does a pump rebuild include?
| Component | What we do | What you get |
|---|---|---|
| Impellers | Inspect for wear, erosion and cavitation damage. Repair, trim or replace. | Restored flow and head |
| Wear rings and clearances | Measure and restore running clearances. Replace or machine wear rings. | Less internal recirculation, better efficiency |
| Mechanical seals and packing | Replace seals or packing. Check sleeves and seal faces. | Fewer leaks and longer seal life |
| Bearings and shafts | Replace bearings, check runout and repair or machine shafts | Cooler, quieter running |
| Casings | Inspect for erosion and cracks. Repair mating faces and fits. | A casing that seals and holds clearances |

How does a pump rebuild work?
Step 1: Receive and record
Log the pump, its service and the symptoms you are seeing.
Step 2: Tear down
Disassemble, clean and tag every part.
Step 3: Inspect and measure
Check impeller, clearances, seal, bearings, shaft and casing. Send you a written scope.
Step 4: Rebuild
Replace or machine worn parts. Restore clearances to spec.
Step 5: Install and align
Set the pump, check pipe strain and laser align it to the motor.
Step 6: Test and report
Run it, check for leaks, heat and vibration, and give you the records.
Signs of pump trouble
When does a pump need a rebuild?
Most pumps warn you before they quit. Watch for these.
- Dropping flow or discharge pressure
- Seal leaks that keep coming back
- Rising vibration or noise
- Gravel or crackling sound from cavitation
- Bearings running hot
- Motor drawing more power for the same output
What is a pump rebuild?
A pump rebuild is a full overhaul that returns an industrial pump to manufacturer spec. We tear it down, inspect every part, replace or repair the impeller, wear rings, seal, bearings and shaft, restore clearances and reassemble it. SSI rebuilds pumps in our Portage, Indiana shop and reinstalls them in your plant.
Pumps move water, slurry, chemicals, pulp stock and process fluids through nearly every plant we work in. A pump that loses flow or leaks at the seal costs you production, energy and cleanup time. A good rebuild fixes the pump and the reason it wore out.
What do we inspect on a pump?
We inspect the impeller, wear rings, seal, bearings, shaft and casing, and we look at the wear pattern for the cause of failure. Erosion, cavitation pitting, rubbing marks and seal face damage each point to a different problem. We fix the cause, not just the part.
| Component | What we look for | What it usually means |
|---|---|---|
| Impeller | Erosion, cavitation pitting, cracks, rub marks | Abrasive service, poor suction, misalignment |
| Wear rings | Opened-up clearances | Normal wear, shaft deflection |
| Mechanical seal | Face damage, heat checking, leaks | Dry running, misalignment, runout |
| Bearings | Spalling, overheating, looseness | Misalignment, contamination, pipe strain |
| Shaft and sleeve | Runout, fretting, grooving | Bent shaft, worn fits, packing wear |
| Casing | Erosion, cracks, worn faces | Abrasive service, age |
How does our machine shop help with pump rebuilds?
Our in-house machine shop makes shafts, shaft sleeves, wear rings and bushings so the rebuild does not wait on outside suppliers. When a pump is old or the part is obsolete, we measure the original and machine a new one to fit. Impellers and seals we source from OEM or quality aftermarket suppliers.
That matters most on older pumps in hard service. A slurry or process pump that has been in a plant for decades may have shaft sleeves or wear rings that no supplier stocks anymore. Rather than wait, we make them to fit the casing and impeller you actually have, and we tell you up front which parts we will make and which we will buy.
Why do rebuilt pumps fail early?
Rebuilt pumps fail early when the conditions that wore out the old one are still there. The usual causes are shaft misalignment, pipe strain on the suction or discharge, a bad base and running the pump far from its design point. We check these on install, not just at the bench.
On every reinstall, our crew:
- checks for pipe strain at the flanges before coupling up;
- checks the base and corrects soft foot;
- performs motor-to-pump laser alignment to OEM tolerance or your plant standard;
- runs the pump and checks for leaks, heat and vibration.
Which plants do we rebuild pumps for?
We rebuild pumps for steel mills, pulp and paper mills, chemical processing plants, power plants and food and beverage plants across Northwest Indiana and Chicagoland. Process and slurry pumps in hard service are a big part of that work.
Pump rebuilds sit alongside our gearbox rebuilds and the rest of our equipment rebuild work. Build pump checks into a preventive maintenance plan and you catch problems before the seal lets go. If a pump is down now, call (219) 386-1506 any time.

Pump Rebuilds FAQs
What does an industrial pump rebuild include?
A pump rebuild includes teardown, cleaning and inspection, then repair or replacement of the impeller, wear rings, mechanical seal or packing, bearings and shaft. We restore running clearances, check the casing and reassemble to spec. On install we check pipe strain and laser align the pump to its motor, then test it.
How long does a pump rebuild take?
It depends on the pump and the parts. Many rebuilds take 1 to 2 weeks. Impellers and seals with long lead times are the usual holdup. Our machine shop can make shafts, sleeves and wear rings, which keeps those parts off the critical path. You get a timeline with the written scope.
Is it worth rebuilding a pump or should I buy a new one?
Rebuilding usually makes sense on larger, engineered or older pumps with a sound casing, where a new pump would mean piping and base changes. Small standard pumps are sometimes cheaper to replace. We inspect it, show you what we find and tell you plainly which way we would go.
What are the signs a pump needs to be rebuilt?
Common signs are falling flow or pressure, seal leaks that keep returning, rising vibration or noise, a gravel-like sound from cavitation, hot bearings and a motor drawing more power for the same output. Any of these is worth a call before the pump fails outright.
Why do mechanical seals keep failing on my pump?
Repeat seal failures usually come from shaft misalignment, pipe strain, worn bearings, shaft runout, running the pump dry or far off its design point. Replacing the seal alone won't fix those. We look for the cause during the rebuild and laser align the pump on install.
Can you repair cavitation damage on a pump impeller?
Often, yes. Light cavitation damage can sometimes be repaired, and badly damaged impellers get replaced. We also look at why it cavitated, such as suction conditions or running off the design point, because a new impeller in the same conditions will be damaged the same way.
What types of pumps do you rebuild?
We rebuild industrial centrifugal, process, slurry and vertical pumps used in steel, pulp and paper, chemical, power and food and beverage plants. We work on many makes and models and source OEM or quality aftermarket parts. Our shop machines parts that are obsolete or hard to get.
Do you remove and reinstall pumps?
Yes. Our field crews pull the pump, bring it to our Portage shop, then reinstall it, check pipe strain and laser align it to the motor. We serve plants across Northwest Indiana and Chicagoland, including Joliet, Kankakee and the Plymouth, Indiana area. For emergencies, call (219) 386-1506.
