Pumps operate by some mechanism either reciprocating or rotary and consume energy to perform the mechanical work by moving the fluid. Long running hours for this type of application give an ideal opportunity to improve performance and reduce energy consumption.


The HVAC/R sector represents a substantial part of the electrical consumption of electric motors worldwide. Due to the high share of the global electrical consumption, these applications are under strong focus of world governments for setting efficiency standards for motors only and then for the whole machine (pump or fan plus motor and drive systems).
