As defined in the Code of Federal Regulations (CFR), “pump” means equipment designed to move liquids (which may include entrained gases, free solids, and totally dissolved solids) by physical or mechanical action and includes a bare pump and, if included by the manufacturer at the time of sale, mechanical equipment, driver and controls. 10 CFR 431.462  Although circulator pumps are a style of pump, DOE has not yet established a test procedure or standards applicable to circulator pumps.

The Department of Energy (DOE) is currently undertaking a rulemaking to consider new energy conservation standards and a test procedure for circulators in an open negotiation process through the Appliance Standards and Rulemaking Federal Advisory Committee (ASRAC).

Recent and Ongoing Activities

DOE has published a Federal Register Final Rule establishing definitions, a test procedure, sampling and rating requirements, and enforcement provisions for circulator pumps. Currently, circulator pumps are not subject to DOE test procedures or energy conservation standards. DOE is adopting a test procedure for measuring the circulator energy index for circulator pumps. The test method references the relevant industry test standard. The definitions and test procedures are based on the recommendations of the Circulator Pump Working Group, which was established under the Appliance Standards Rulemaking Federal Advisory Committee.

  • The effective date of this rule is October 19, 2022.
  • Compliance with the final rule will be mandatory for representations of head, flow rate, driver power input, circulator energy rating, and circulator energy index made on or after March 20, 2023.

For the latest information on the planned timing of future DOE regulatory milestones, see the current Office of Management and Budget Unified Agenda of Regulatory and Deregulatory Actions. All planned dates are preliminary and subject to change.
