Product Overview

The Pentair 355027S is a replacement single speed square flange motor used in compatible Pentair pool pump assemblies. Pentair’s current pump parts catalog and SuperMax replacement parts sheet identify this SKU specifically as a black 2.5 HP motor with single speed, 1 phase, 60 Hz, and 208-230V specifications. That makes exact part-number matching important during repair and maintenance, especially when the original motor must be replaced without changing the mounting style or electrical setup.

This replacement motor is best suited for service situations where the original motor has failed or no longer performs as intended, while the remaining pump assembly is still serviceable. For ecommerce accuracy, the safest retail positioning is Pentair 355027S 1 Speed Black Square Flange Motor, 2.5 HP, 208-230V, because Pentair’s official parts documentation supports that specification rather than a 2 HP description for this SKU.
