Hypro 3430-0589 Silicon Carbide Centrifugal Pump wet end Repair Kit
This seal utilises silicon carbide for its seal surfaces.
Silicon Carbide is more abrasion-resistant than the carbon graphite and ceramic used in standard seals.
Silicon Carbide also runs cooler if the pump is run dry, improving the life of the seal.
