Submersible Well Pump

Submersible well pumps deliver dependable water from deep wells for homes, farms, and light commercial systems. Pair a multi-stage pump end with a matching submersible motor to hit your target flow (GPM) and total dynamic head (TDH), then finish with the controls and drop-pipe accessories you need.

Shop by need

• Diameter: 4", 6", and larger pump ends for standard and high-flow wells
• Flow & head ranges: shallow to deep sets, from low-flow efficiency to high-yield irrigation duty
• Materials: stainless steel and engineered polymer stages for strength and sand resistance
• Motors: single-phase (2-wire/3-wire) and three-phase, NEMA mountings
• Controls: control boxes, pressure/flow switches, VFD constant-pressure drives
• Accessories: check valves, splice/heat-shrink kits, torque arrestors, flow sleeves, pitless adapters, drop pipe, and submersible cable

Quick choosing guide

1. Define demand: total the household or system GPM and calculate TDH (static water level + drawdown + elevation to tank + friction loss).
2. Select pump curve: choose a pump series that delivers the required GPM at your TDH with some mid-curve operating margin.
3. Match the motor: pick horsepower and voltage that the curve calls for. 2-wire (no external box), 3-wire (needs a control box), or three-phase for longer runs/VFDs.
4. Check well size & cooling: verify casing I.D. (4", 6", etc.). Use a flow sleeve if the well is large-diameter, a cistern, or a horizontal install to ensure motor cooling.
5. Plan controls: classic pressure-switch + tank, constant-pressure VFD, or flow-switch solutions—add run-dry/over/under-voltage protection.
6. Finish the drop: include a check valve at the pump discharge (and along the drop per code), torque arrestor, safety rope/strap, heat-shrink splices, pitless adapter, and properly sized submersible cable.
