Product Overview

The Pentair 071725S shaft seal is an essential internal component used in C-Series and EQ-Series commercial pool and spa pumps. Installed between the pump impeller and motor shaft, the seal forms a watertight barrier that prevents water from leaking into the motor housing while the pump shaft rotates during operation.

Manufactured from durable sealing materials such as carbon graphite, ceramic, stainless steel, and chemical-resistant elastomers, the shaft seal is designed to handle the demanding operating conditions found in commercial pool circulation systems. Replacing worn shaft seals during pump maintenance helps prevent motor damage, maintain proper system pressure, and ensure long-term pump reliability in high-duty applications.
