This Commercial Item Description (CID) covers electric-motor-driven, centrifugal, water circulating pumps for use in hot water heating systems and service water distribution systems. The pumps have in-line connections to permit unsupported installation of the units in a straight run of piping. Pumps covered by this document are intended for use as circulators in forced hot water heating systems, and in service water distribution systems, where the water temperature for either application does not exceed 225°F (107°C).
