Manufacturers navigate the road to compliance for clean-water pumps

The DOE began the process to regulate clean-water rotodynamic pumps in 2011, with the goal of reducing the overall demand for energy in the United States. Leaders in the pump industry, through the HI, have been working shoulder to shoulder with the DOE to develop pump efficiency standards and test procedures. As such, the test procedures closely follow HI's existing test methods contained in HI 40.6-2014, Methods for Rotodynamic Pump Efficiency Testing.

In a 2015 retrofit at a New York City high-rise, constant-speed pumps were replaced with high-efficiency pumps with variable-speed drives for the building’s chiller system. The advanced hydraulics of the new pumps alone resulted in an immediate and sizable energy reduction over the old pumps.
