Maintaining pumps saves energy


Pump efficiency deteriorates over time leading to energy wastage. Efficiency losses of between five and 15 per cent can occur after 10 years of operation.

Typical pump overhaul includes: replacement of wear rings, seals, bearings and worn impeller; cleaning of internals, blast cleaning of externals and applying new epoxy coating.
