MAINTENANCE & PARTS FOR WARMAN PUMPS
In Brazilian mining, "slurry pump" is almost synonymous with Warman — and these pumps' wear parts are the item that consumes most of the maintenance budget. Hydro Pumps restores and supplies compatible components in high-hardness materials, breaking the endless replacement cycle.
Hydro Pumps is an independent maintenance and parts supply company, with no commercial affiliation to Warman or the Weir group. The brands cited belong to their respective owners and are mentioned exclusively to indicate application compatibility.
What we service in the Warman fleet
Slurry pumps and severe abrasive service — restoration and compatible replacement.
Slurry and tailings pumps
Inspection and complete repair of the mine's most severe-service pumps.
Impellers for abrasion
Restoration with high-hardness coatings or manufacture in wear-resistant alloys — balanced to G2.5.
Liners and wear plates
Wear components in materials selected for your slurry's actual abrasiveness.
Shafts and bearings
Restoration of shafts, bushings and bearing assemblies for continuous operation.
Slurry sealing
Packing and sealing specified for abrasive solids.
Replacement assemblies
Complete rotating assemblies ready for fast swap at the planned stop.
Against abrasion, metallurgy — not recurrence
The wear cycle can be broken
Slurry pump parts are consumables — but the consumption rate depends on the material. We restore Warman impellers and components with high-hardness alloys and coatings applied under controlled processes, extending replacement cycles beyond standard spares.
The result is measured in availability: fewer interventions per year, fewer circuit stops and a predictable maintenance budget.
Replacement designed for the shutdown
Mining swaps parts within short windows. We work with pre-assembled sets and strategic stock for critical positions, ready for fast swap — and the removed part returns to the cycle as a restored spare.
For emergencies outside the window, our 24/7 service puts crew and components at the mine in any region.
Warman pump maintenance questions
What mining maintenance teams ask.
01Do you supply parts compatible with Warman pumps?
Yes — impellers, liners, wear plates, shafts and bushings, manufactured or restored in high-hardness alloys selected for your slurry's abrasiveness. Provide the pump model for a quote within 24 hours.
02How long does a restored part last versus a new one?
It depends on the applied material: restoration with an alloy and coating superior to standard frequently exceeds the life of a common replacement part in abrasive service. We track your operation's actual cycles to calibrate the specification.
03Do you have rotating assemblies ready for shutdown swaps?
Yes — we build complete assemblies, balanced and tested, ready for fast swap within the window. The removed pump goes to restoration and returns as the next cycle's spare.
04Do you serve mines in an emergency?
Yes, our 24/7 service covers emergencies in any region of Brazil: a field crew for diagnosis and swap, and urgent repair at the workshop when the component is critical.
