Stainless steel fasteners enhance serviceability, and the 2″ NPT discharge (with a 3″ adapter option) offers flexible installation. Equipped with an SJE pump master float switch for automatic operation, this pump is ideal for residential and light commercial applications. The WS51 Series delivers consistent performance and rugged reliability for demanding sewage and effluent tasks.
