How to Choose a Submersible Well Pump

Start with your well details, water demand and electrical supply. We can help match a pump to your application.

Check Your Well Diameter

Confirm the inside diameter of your well casing and the clearance needed for the pump and cable. Check the exact model dimensions before choosing a replacement.

Match Lift and Pressure

Use the pumping water level, desired delivery pressure and pipe losses to determine total dynamic head. Check the pump curve at your required flow; well depth alone does not determine the correct pump.

Plan for Water Demand

Consider how many fixtures or irrigation zones run together and how much water the well can supply. Match the required gallons per minute to your well recovery rate and system design.

Match the Motor and Controls

Check horsepower, voltage, phase and motor wiring. Single-phase 3-wire motors require a matching control box. Send us your existing pump and control-box model numbers for help.

Frequently Asked Questions

  • A submersible well pump operates underwater inside the well and pushes water to your home, irrigation system or storage system. Choose a model suited to your well and water demand.

  • A submersible pump is installed in the well, while a jet pump normally sits above ground. The appropriate system depends on your well, water level and installation. Contact us before changing pump types.

  • Sizing depends on well diameter, pumping water level, required flow, delivery pressure, pipe losses and well recovery. Share these details and your existing model number with us for help selecting a pump.

  • No. Pumps with the same horsepower can have different flow and head capabilities. Compare the exact pump curve, electrical requirements and installation dimensions.

  • These descriptions refer to motor power leads; the grounding conductor is additional. Single-phase 3-wire motors use a separate, matching control box. Check the motor specifications and wiring instructions before ordering.

  • A pump end is the hydraulic section and does not include the motor. Confirm whether the listing includes a motor and whether a control box is included. Match replacement pump ends to the required motor and application.

  • Depending on your installation, you may need a compatible control box, submersible pump wire, waterproof splice kit, pressure tank and pressure controls. Browse well essentials or ask us to help check compatibility.

  • Check the exact product specifications before purchasing. For Goulds GS models, see the GS technical brochure and pump curves and submersible pump installation manual.

  • Yes—we can order any CS, GS, or HS Series version. Send us the model number or a photo of your existing pump label, and we’ll confirm pricing and availability.

  • Contact Electric Motor Service at (925) 934-4582 to confirm availability and local pickup at our Walnut Creek store. For shipped orders, check the specific product’s shipping information and delivery options at checkout.
