Product Overview

The Pentair 071734S PS1000 shaft seal is an essential internal component used in many pool and spa pump systems. Installed between the pump impeller and motor shaft, the mechanical seal forms a watertight barrier that prevents water from entering the motor while the pump operates.

Manufactured with durable sealing materials and a ceramic seat, the seal is designed to withstand continuous exposure to water pressure, heat, and pool chemicals. The PS1000 seal is commonly used in compatible pump systems including models such as WhisperFlo and IntelliFlo, where reliable shaft sealing is necessary to maintain pump efficiency and protect critical motor components.
