Non-Destructive Testing & Analysis
Each of our facilities has in-house capabilities and also partners with experts in non-destructive testing techniques, such as MPI (Mag Particle Inspection), LPI (Liquid Penetrant Inspection), RT (Radiography testing), and UT (ultrasonic testing). Our engineers use NDE test results to develop strategies for repairing and replacing components. Each of our facilities has hydro testing capabilities to ensure casting integrity, and Westpower Group operates a full performance test stand to ensure pump performance as required.
Component and Rotor Balancing
Each repair facility is equipped with multi-plane balancing for all necessary components and assemblies. We balance to better than API 610 as a standard or other specifications per client instructions.
Pump Re-Rates and Upgrading
Our pump re-rating and upgrading services optimize your equipment for changing process demands or to increase MTBR. Based on your goals, our engineers offer hydraulic, mechanical, and metallurgical/material modifications to improve your pump performance.
Off-site / In-House Pump Repair
Westpower offers both repairs in the field by qualified technicians and at our multiple repair facilities. Our field technicians provide on-location troubleshooting, disassembly and reassembly, while complex repairs are handled at our repair facilities. Westpower’s expert repairs optimize pump performance and reduce operational disruption.
Westpower’s advanced pump repair centers in Calgary and Edmonton are equipped with boring mills, lathes, grinders, dynamic balancing machines, and HVOF coating systems for complex pump repairs. Our specialized team of qualified tradespeople includes machinists, millwrights, and welders who work with our engineers to restore API, ANSI, ASME, and other industrial pumps. Our in-house expertise in machining, boring, balancing, and coating ensures high-quality and timely pump repairs and upgrades for all of your sites across Western Canada.
We’ve yet to receive a pump that we couldn’t repair, overhaul, and return to service. We specialize in a wide range of pump repairs, including centrifugal, reciprocating, vacuum, axial piston, diaphragm, and screw pumps, from fractional HP metering pumps to over 5000 HP process, power generation, and pipeline pumps. Our expertise covers ISO, API, ASME/ANSI, Hydraulic Institute and other industrial standards across various pump categories for all types of positive displacement and centrifugal pumps.

Pump systems evolve, and so do their operational demands. Westpower’s 4R approach: Redesign, Rerate, Remanufacture, Replace, ensures your pumps perform optimally in any condition. Whether upgrading, adapting, or replacing, our engineered solutions deliver efficiency, reliability, and cost savings.
We enhance OEM designs to improve Mean Time Between Repairs (MTBR) and resolve operational challenges. By strengthening weak points in the original design, we address system changes and evolving application demands. Our redesigns include material upgrades, rotor modifications, optimized hydraulic passageways, and bearing housing enhancements.
We modify pump hydraulics to better match current or future desired operating conditions, optimizing efficiency and performance. This process typically involves hydraulic modifications with our in-house engineering to design and manufacture components.
We refurbish surplus new or used equipment to meet specific operational requirements, reducing lead times and ensuring seamless integration. Remanufacturing allows for much quicker lead times than manufacturing a new pump while meeting all of your operational requirements.
We provide exact pump replacements to eliminate costly site rework, avoiding modifications to piping, baseplates, or electrical infrastructure. Where beneficial, we can also integrate redesign and rerate enhancements within the existing pump envelope. This is most often requested when the OEM will no longer support an older pump design, the OEM cost and delivery is excessive, or facility retrofits such as piping are prohibitively expensive.
We don’t just fix pumps, we improve reliability and reduce lifecycle costs with smarter solutions.
