Description
Premium Silicon Carbide PS-200 Shaft Seal (PS-1901) – the superior salt-resistant upgrade designed for Aqua-Flo wet end assemblies, also compatible with Waterway “Viper” and “EX2” models and select other configurations.
Silicon Carbide construction delivers outstanding resistance to wear and chemicals, superior dry-running performance, and extreme hardness – ideal for harsh, corrosive conditions and elevated temperature applications.
Specifications: Both the spring seal assembly (impeller mount) and ceramic/rubber component (volute insert) measure 1 1/4″ across. Center bore diameter on both pieces: approximately 5/8″. The spring-loaded portion mounts to the impeller shaft while the ceramic/rubber section inserts into the volute or wet end housing. Installation tip: Apply silicone sealant to the impeller shaft before gently sliding the spring seal into position. A thin layer of silicone on the rubber component helps ease installation into the volute or wet end body. Additional impellers and silicone sealant available in our store.
*Important: For Waterway wet ends, this seal fits “Viper” and “EX3” models exclusively – all other Waterway configurations require a 1000-series seal.
