  • The submersible effluent pump offers a reliable performance and value for high pressure filtered effluent applications.

    The Sta-Rite Step 20-3 / ½ HP Effluent Pump has a stainless steel and composite construction, which gives the pump superior performance. The pump also features an exclusive industry dry-run capability and a serviceable fiberglass reinforced thermoplastic intake screen. This tested fiberglass -reinforced thermoplastic is extremely tough so that it can withstand wear. 

    The Sta-Rite Step 20-3 / ½ HP Effluent Pump is also extremely durable. The shell is a 300-grade stainless steel shell that offers high corrosion resistance. The pump also features an enclosed and self-lubricated Nylatron shaft and bearings that resist wearing from sand. The Proven “floating impeller” staging system incorporates first-in-class performance, and handling, and thrust management to give you the best experience possible.


    The Sta-Rite Step 20-3 / ½ HP Effluent Pump should last for years, however, if your old Sta-Rite Step 20-3 ½ HP Effluent Pump is starting to slow down, or has stopped working, this model is an exact replacement. The Sta-Rite Step 20-3 ½ HP Effluent Pump typically needs little maintenance; however, the owners manual comes with an intuitive troubleshooting guide, so you can diagnose any issues yourself before buying a new model.
