What abrasion costs you
A worn impeller does not just look bad. Opened-up clearances and a rough, eroded volute push the pump away from its best efficiency point. Flow drops, power draw climbs and vibration rises. Many plants respond by running the pump harder, which speeds up the wear. Rebuilding the hydraulic surfaces restores clearances and smooths the flow path, and that often recovers a noticeable share of lost efficiency.
How we rebuild worn parts
- Measure. We record wear on vanes, shrouds, wear-ring seats and the cutwater against the original profile.
- Blast. Eroded surfaces are blasted clean and profiled for maximum adhesion.
- Rebuild. A ceramic-reinforced paste compound restores lost metal and re-forms vane tips and the cutwater.
- Top coat. A smooth, ceramic-filled brushable coat lowers surface friction and adds an erosion-resistant layer.
- Balance & check. Rotating parts are dressed, checked for clearances and balanced where required.
Typical applications
We handle borehole and irrigation pumps from the Winelands and West Coast farms, dewatering and slurry pumps from quarries and construction sites, cooling water pumps, and process pumps in the industrial nodes around Bellville, Kuils River and Brackenfell. Where wear and corrosion work together, as they usually do in water service, we pair this with our corrosion coating system or move to a full pump rebuild.
Wear & Abrasion Coating across the Western Cape
We provide wear & abrasion coating from our Bellville workshop to clients throughout the region, including Bellville, Cape Town CBD, Parow & Goodwood, Epping Industria, Montague Gardens, Milnerton, Durbanville, Brackenfell, Stellenbosch, Paarl, Saldanha Bay, George.
