Belzona Coating For Pumps

Corrosion, erosion, and internal wear can reduce pump efficiency, increase energy costs, and lead to early failure. Banks Industrial Group provides pump coating services using advanced Belzona epoxy systems to restore internal surfaces, reduce hydraulic losses, and extend equipment life. Our cold-applied coatings protect components like impellers, volutes, and vanes—reducing friction, improving flow, and boosting efficiency. No hot work is required, and most applications are completed quickly to avoid disruption. We offer these services directly to municipal and industrial maintenance teams, as well as a subcontracted solution for pump repair contractors seeking reliable coating expertise with fast, safe, and responsive service.

What We Like About Belzona Pump Coatings:

Trusted worldwide for decades, Belzona coatings are supported by extensive testing and real-world success. They are suitable for application to volutes, casings, impellers, diffusers, vanes, cutwaters, pump bowls, and other critical components to enhance efficiency and ensure long-term protection from wear.

  • Improve Efficiency up to 20%: Belzona reduces internal surface roughness, allowing fluid to flow more easily and reducing energy demand – up to 12% for new pumps, older pumps up to 20%
  • Reduce Energy Costs Immediately: Smoother flow paths and reduced friction result in less power required to move the same volume
  • Rapid ROI: Efficiency payback periods generally under one year for continuously running pumps
  • Extend Equipment Life: Coatings create a tough barrier against corrosion, erosion, and chemical attack – protecting vital pump internals for years
  • Avoid Costly Replacements: Metal refurbishment and protective coatings offer a long-term alternative to new pump components, preserving capital budgets
  • No Hot Work Required: Cold-curing application eliminates the risks and delays associated with welding and thermal coatings
  • Fast Turnaround, Minimal Downtime: Most coating applications are completed in days, allowing you to return to full capacity quickly
  • Potable Water: Optional coatings safe for contact with drinking water are available
  • Backed by Belzona’s Proven Performance: Trusted worldwide for decades, Belzona coatings are supported by extensive testing and real-world success

belzona 1341 supermetalglide hydrophobic pump coating applied to split case centrifugal pump to improve efficiency

We applied energy saving Belzona 1341 SuperMetalGlide hydrophobic coating as part of the refurbishment of this split case centrifugal pump.

What is a Hydrophobic Coating, and Why Use it?

Belzona 1341 hydrophobic protective coating forms a durable, high-gloss, ceramic epoxy barrier that actively repels liquids from pump surfaces. This ultra-smooth finish significantly reduces friction and turbulence inside the pump, which means less energy is needed to move fluids—improving overall pump efficiency and lowering operational costs. By isolating the metal from corrosive fluids, the coating helps prevent rust, pitting, and erosion, dramatically extending the pump’s service life and maintaining peak performance over the long term.

Both new and existing pumps benefit from this advanced coating solution. Its simple, cost-effective application minimizes downtime and quickly delivers a return on investment through energy savings and reduced maintenance

BIG Pump Coating Examples


eroded suction pump volute casing

Casing with erosion damage is grit blasted to near-white metal.

Areas of metal loss are filled with Belzona 1111 epoxy paste.

base coat of gray color belzona 1341 pump efficiency coating applied to suction pump volute casing

Volute is re-profiled and first coat of gray color Belzona 1341 is applied.

final coat of blue color belzona 1341 pump efficiency coating applied to suction pump volute casing

Second coat of blue color Belzona 1341 is applied to all internal water ways.

We Restore Lost Pump Efficiency

This industrial suction pump experienced corrosion and erosion at the surface where the open impeller vane tips operate, resulting in a 38.8% loss of efficiency. The severely corroded volute casing was restored using Belzona 1111 epoxy paste and re-profiled for optimal fit with the impeller vane tips. A protective coating of Belzona 1341 was then applied to enhance hydraulic efficiency, flow rate, and head performance.

Before: Damaged wear ring seats and volute are grit blasted for repair work.

split case pump wear ring repair and protective coating

After: Wear ring seats rebuilt and pump efficiency coating applied.

Centrifugal Pump Volute Coating

Our technicians restored cracked ring seats using Belzona metal repair epoxy and specialized forming techniques. To further enhance performance, the volute was coated with Belzona 1341 hydrophobic coating.

newly fabricated open impeller coated with belzona 1341 pump efficiency coating
