SEE REPLACEMENT PART: OBSOLETE

The Pentair D Series 3 HP Self Priming Centrifugal Pump is a replacement component from Pentair Pool Products intended for use in compatible pool, spa, and bath equipment where the matching size, model series, and part number are required. This pump or pump-related assembly is used to support water movement through compatible pool, spa, or bath systems. Pumps must be matched by horsepower, speed, voltage, amperage, plumbing connection, wet-end configuration, and equipment application, since similar models can look alike but perform differently. Replacing a failing pump can help restore circulation, jet action, filtration flow, or equipment operation depending on where it is installed. Because many equipment families use similar-looking parts with small dimensional or configuration differences, compare the existing part, equipment label, plumbing size, voltage where applicable, and part number DMH3-171 before ordering. This description is intended to help customers identify the product's purpose and confirm fit before purchase, but the original equipment manual, exploded parts diagram, or service technician should be used whenever exact compatibility is uncertain.
