Oversized pumps waste energy
Energy used in irrigation can account for upwards of 50% of a farm’s total energy bill. Pump duties are often overestimated at the design stage of an irrigation scheme, which can result in the installation of oversized pumps. As well as costing more to install, larger pumps consume more electricity and so have higher operating costs.

A pump is generally oversized when it is not operating at or within 20% of its best efficiency point (BEP), although it is normally considered acceptable if the duty point fall within 50 to 110% of the BEP flow rate. By replacing oversized pumps with smaller ones, energy and maintenance savings can be achieved due to lower power consumption requirements and less wear and tear.

Selecting the right pump for the job will ensure that the pump runs efficiently, increasing the lifespan and reliability of the equipment. By replacing oversized pumps with smaller ones, or by reducing the size of the impeller, energy and maintenance savings can be achieved due to lower power consumption and less wear from excess flow energy.
