Heavily damaged pumps can be restored to their original profile using WPS’s cold-curing metal repair composites. Our epoxy coatings for erosion-corrosion protection reduce further deterioration, increasing pump efficiency and lowering frequent maintenance costs.
Pump Repair
Pump performance can decrease after prolonged, heavy-duty or aggressive service due to erosion, corrosion, chemical attack, wear, and cavitation.
WPS’s range of metal repair composites:
- Rebuild the pump casing and impeller without the need for specialist tools
- Restore wear ring clearances
- Provide long-term corrosion and erosion protection
- Avoid the need for hot work
- Cure at ambient temperature
- Provide excellent adhesion to metal substrates, including stainless steel, duplex steels, carbon steel, aluminium, cast iron, bronze, and specialist alloys
- Protect against pump cavitation
Pump Protection and Efficiency Improvement
WPS supplies a wide range of epoxy coatings designed for various service conditions.
Our ceramic coatings provide long-term erosion-corrosion protection. We also offer products specifically designed to improve pump efficiency, using hydrophobic technology to repel process fluids and reduce turbulent flow. Efficiency improvements of up to 7% have been recorded on new equipment and up to 20% on refurbished equipment.
For heavy wear situations, such as sludge or sewage pumps, we offer abrasion-resistant linings that incorporate extremely hard fillers to provide maximum protection.
Additionally, protection of pump shafts against wear and seizure can be achieved using our bearing metal, which creates low-friction surfaces due to its self-lubricating composition.
End covers, valve plates, and rotors from vacuum pumps can also be rebuilt and protected using our metal repair materials.
Other specialist coatings incorporating chemical, high-temperature, erosion, and cavitation resistance, or a combination of these properties, ensure WPS has solutions for nearly all service conditions.
Once in service, any local damage to coatings can be easily repaired, ensuring a rapid return to service and minimizing downtime.
