Everyone is probably familiar with the impact of energy efficiency efforts on our industry. For electric motors, this has been both a concern and an incentive for innovation. EASA members and manufacturers have been shaped by the governmental and market forces aimed at reducing electrical energy usage. Electric motors are a primary target of these “green” efforts.

But the commercial and regulatory landscape is ever evolving, and the horizon coming into view includes a new focus on pumps and pump systems. The U.S. Department of Energy (DOE) is implementing efficiency standards for rotodynamic pumps (centrifugal and axial flow pumps). The standards will have little effect on the pump repair market, while pump manufacturers are directly affected. But pump efficiency is very different from electric motor efficiency.

Even regulators writing the efficiency requirement for pumps understand that it is the system to which the pump is connected that dictates the efficiency of the pump. Both the Hydraulic Institute (HI) and the CSA Group have initiatives in progress to set standards for measuring and reporting pump system efficiency.

This emerging interest in pump and pump system efficiency creates opportunities for EASA members involved in pump repair, who represent pump vendors, or who may be moving in that direction.
