There's only one spare part for a Warman® pump — a genuine Warman® spare part. Compatible replacement parts manufactured to exact OEM specifications.
All Warman® centrifugal pumps are designed, manufactured and installed to operate under demanding conditions that place every component in the pump under a significant amount of stress.
When you buy replacement parts for Warman® slurry pumps, you get so much more than just a volute liner, impeller or side liner. Instead, you're making an investment in a product that will receive expert lifetime support, achieve higher pump performance, last longer and reduce your process' risk profile.
Our range of replacement parts provide the following benefits:
Our range of Warman® pump impellers are manufactured to be the proper dimensional and hydraulic fit with our supplied volutes and liners. This ensures that engineered tolerances are adhered to and hydraulic performance is as designed.
Impeller threads are machined with custom inserts and very tight controls on thread diameters to create a proper robust assembly.
Our pump liners (throatbushes and frame plate liner inserts) are expertly engineered to provide superior function, fit and performance within our range of Warman® pumps.
These parts are offered in multiple variants to suit a wide array of duty conditions and wear life targets.
Warman® pump volutes and volute liners can be made from a range of materials to ensure performance in a range of applications and to ensure that pressure and head requirements are met.
Choose the right material for your specific application conditions.
High-chromium white irons that deliver excellent wear resistance in moderate to highly corrosive environments. Our most popular alloy is Ultrachrome® A05, which contains approximately 27% chromium by weight. It provides a great balance of hardness and toughness, effective for general-purpose pumping and applications with very large solids (up to 300mm) at pH4 or above. Provides modest corrosion resistance for impellers, casings, volute liners and throatbushes.
Hypereutectic iron-chrome alloys featuring high proportions of chromium carbide. A61 contains 50% chromium carbide for outstanding erosion resistance — ideal for mill discharge slurries with broad particle size distribution.
A68 combines the robust wear resistance of A61 with the anti-corrosive properties of Ultrachrome® A05 — ideal for moderately corrosive environments requiring harder material than A05.
Highly wear-resistant overlay material engineered for extreme abrasion environments. Applied selectively to high-wear zones such as the impeller eye rather than coating entire components. Field data in oil sands operations has demonstrated markedly improved wear life compared with white iron.
| Material | Type | Best For | Key Properties |
|---|---|---|---|
| R55® Natural Rubber | Natural Rubber | Most mill circuit applications | Premium-grade, low hardness, highly wear-resistant |
| R508 Natural Rubber | Natural Rubber | Mill discharge, large-particle erosive applications | High resilience, high tear strength, superior cut resistance |
| Linatex® Premium Rubber | Natural Rubber | Wet sand applications | Extremely strong, tough and resilient |
| S42 Polychloroprene | Neoprene | Oil sands, hydrocarbon environments | Temperature-resistant, excellent weathering/ozone resistance |
| U38 Polyurethane | Polyurethane | Tailings, flotation, leach duties | Erosion-resistant, excellent where "tramp" is a problem |
Our team follows stringent quality control standards and extensive safety testing to ensure that each part undergoes lengthy and precise design processes.
Replacement parts are built in state-of-the-art manufacturing facilities all over the globe, with specific heat treatment, proprietary moulding and high quality casting.
Installation of non-genuine parts may adversely affect the performance and safety features of our products. The failure to properly select, install or use authorised parts is considered misuse, and damage or failure caused by misuse is not covered by warranty.
