The PS-201 shaft seal is engineered specifically for Vico and Sta-Rite wet end assemblies, delivering reliable performance in spa pump applications. This dual-component seal system features both pieces measuring 1 3/8" across, with 3/4" center holes designed for proper shaft fitment.

The assembly includes a spring-loaded seal component that mounts directly onto your impeller shaft, plus a ceramic and rubber element that installs into your volute or wet end housing. Compatible with Sta-Rite, Vico, and most Cal Spa pump models including Power Right series.

Installation Guidelines: Apply a thin layer of silicone lubricant to the impeller shaft before carefully sliding the spring seal component into position. The rubber seal element also benefits from light silicone application for smooth insertion into the volute body.

Important Service Note: When replacing a failed seal, impeller replacement is typically recommended. Leaking seals allow water penetration into the metal shaft housing, causing corrosion and expansion that often damages the impeller threads.

This Buna material seal provides dependable service for standard spa pump applications. Upgrade options include Viton (PS-3868) and Silicon Carbide (PS-1902) versions for enhanced durability in demanding conditions.
