Even slight wear of the workingwheels leads to a drop in the pressure created by the pump, and this reduces the pump's performance and increases energy consumption.
The causes of wear are polluted water, abrasive suspension, strong mineralization of water... Wear can be reduced by installing a powerful inlet filter, which must be changed, cleaned... so as not to lose productivity.

The impeller of the centrifugal pump is brass.
