Flotec FP3332 1 HP Submersible Well Pump – 20 GPM, 230V 3-Wire, 4" Pump with Control Box Included

High-Flow 1 HP Submersible Well Pump for Shallow to Mid-Depth Wells The Flotec FP3332 1 HP Submersible Well Pump (20 GPM) is designed for applications where higher flow rates are required at moderate depths. Ideal for residential homes, farms, and irrigation systems, this pump delivers strong water output while maintaining energy efficiency. Built for 4" diameter wells or larger, the FP3332 operates effectively at depths up to 150 feet, making it a strong choice for shallow to mid-depth wells. The 3-wire, 230V configuration includes a control box, simplifying installation and ensuring reliable motor operation. The floating stack impeller design improves resistance to sand and reduces the risk of sand locking, while the stainless steel construction provides excellent corrosion resistance for long-term durability. A built-in check valve helps maintain system pressure and prevents backflow.
