Sta-rite HS "Stainless Steel" Submersible Well Pump, 50GPM

Sta-rite HS "Stainless Steel" Submersible Well Pump, 50GPM

The Sta-Rite HS Series 4" Stainless Steel Submersible Well Pump is a high-capacity, precision-engineered pump built for demanding water systems where performance and durability matter most. Designed for 50 GPM output with a 2" discharge, this pump uses a floating impeller system and SignaSeal™ staging technology to handle abrasives, sand, and aggressive water conditions with confidence. Built from corrosion-resistant stainless steel, it’s made for long-term, trouble-free operation—because pulling a deep well pump twice is a lesson most people only want to learn once.
