Circulator Pumps

As defined in the Code of Federal Regulations (CFR), a “circulator pump” is a pump that is either a wet rotor circulator pumps; a dry rotor, two-piece circulator pump; or a dry rotor, three-piece circulator pump. A circulator pump may be distributed in commerce with or without a volute. 10 CFR 431.462.

  • DOE has published a Federal Register final rule pertaining to energy conservation standards for circulator pumps. The Energy Policy and Conservation Act (EPCA) requires DOE to periodically determine whether more-stringent, standards would be technologically feasible and economically justified, and would result in significant energy savings. In this final rule, DOE is adopting new standards for circulator pumps. It has determined that the standards for this equipment would result in significant conservation of energy, and are technologically feasible and economically justified.

    • The effective date of this rule is August 5, 2024
    • Compliance with the standards established for circulator pumps in this final rule is required on and after May 22, 2028.

    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.
