Industrial pump repair without hot work
Centrifugal and positive-displacement pumps suffer cavitation, erosion-corrosion, chemical attack and particle wear. Induscoat repairs pump casings, pipes, flanges and shafts with cold-curing epoxy composites — no welding, no heavy machining, no extended downtime. Service in Quebec, Ontario and across Canada.
The challenge: pumps worn by cavitation and erosion
In mines, cement plants, refineries and chemical plants, pumps handle slurries, acids, wastewater and hydrocarbons. Cavitation, erosion-corrosion and abrasion degrade the pump casing, impeller eye, wear rings and flanges. Replacing the pump costs 5 to 20 times the price of a repair and often requires weeks of lead time. Welding on a cast iron or coated steel casing risks cracking and requires rebalancing.
The solution: cold-curing epoxy composites
Induscoat applies formulated epoxy and polymer repair systems that bond to cast iron, steel, bronze and stainless steel even on wet or lightly oiled surfaces. The original geometry is rebuilt by moulding, then the surface is protected with a fluid anti-corrosion coating. No heat input, no distortion risk, no rebalancing wait.
Diagnosis of the wear mechanism (cavitation, erosion, chemistry, temperature)
Surface preparation: grit blast to NACE 2 / SSPC-SP10 near-white metal
Application of repair mastic and moulding to original geometry
Anti-corrosion topcoat and documented adhesion testing
Why repair instead of replace
- Cost 5 to 20× lower than full pump replacement
- Turnaround of days vs weeks for a new pump
- No hot work — no permits, no fire risk
- Bonding to cast iron, steel, bronze, stainless (wet-surface tolerant grades)
- Broad chemical resistance: acids, bases, hydrocarbons, wastewater
- Typical service life 5 to 10 years depending on duty
Systems we apply
Induscoat selects the exact composite based on your fluid, temperature and particle load. We apply high-performance cold-repair systems, anti-corrosion finishes and our own Induscoat formulations for Canada's most demanding services.

Frequently asked questions
How long does an epoxy pump repair last?+
A properly applied repair after NACE 2 grit blasting typically delivers 5 to 10 years of service depending on the pumped fluid, temperature and particle load. We provide a recommended re-inspection interval with every project.
Can a pump be repaired in service, or must it be stopped?+
Most repairs require stopping and isolating the pump for grit blasting and application. However, cold-curing composites reduce the outage window to 24 to 48 hours, versus several days for a replacement.
Do you repair all pump types?+
Yes: centrifugal, positive-displacement, submersible, side-channel, circulation, discharge and process pumps. We repair casings in grey cast iron, ductile iron, carbon steel, bronze, duplex and stainless steel.
Which sectors do you serve in Canada?+
Mining (Abitibi, Sudbury, Timmins), cement, refineries, chemical plants, pulp and paper, water treatment and power generation — in Quebec, Ontario and Canada.

Heavy machinery epoxy grouting: foundation repair and grout design for SAG mills, crushers, compressors and turbines
SAG and ball mills, crushers, reciprocating compressors and turbines load their foundations with weight, cyclic forces, impact and heat. Epoxy grout is the usual link between the machine and the concrete, but most grout failures come from design and pour, not from the product. This guide covers grout design, anchor bolts, concrete preparation, the pour and how to verify the result.
9 minValve body repair with epoxy: when to rebuild, coat or replace an eroded or corroded valve
Butterfly, knife gate, plug, check and cast iron gate valves all wear in predictable places. When the pressure wall is still sound, a metal- or ceramic-filled epoxy rebuild restores the body and its seat areas without welding. This guide covers where each valve type wears, how to read the damage, when to repair or replace, and how the repair is done and tested.
10 minPump foundation and baseplate repair: when epoxy grout beats re-pouring the concrete
A pump that loses alignment, vibrates after every overhaul, or shows cracked grout around the baseplate has a foundation problem, not a pump problem. Replacing bearings and seals treats the symptom. This guide covers how to tell a foundation failure from a machine failure, what epoxy grout does that cementitious grout cannot, and when the concrete itself has to be rebuilt.
6 minCentrifugal pump repair procedure: rebuilding the casing and impeller with epoxy
Cavitation, erosion and corrosion eat pump casings and impellers long before the rest of the pump is worn out. This guide covers how to identify the damage mechanism at teardown, the step-by-step epoxy repair procedure, which material suits which mechanism, and when the part should be replaced instead.
