MYERS SUBMERSIBLE PUMPS

Designed for standard 4-inch or larger well casings, the Myers line includes 4-inch submersible well pumps built for reliability. Each pump features full stainless steel construction, self-lubricating impellers that operate without external lubrication, and industry-standard Franklin Electric motors backed by a widespread parts and service network. Well pump professionals frequently select this series for its long-lasting performance under tough operating conditions and the widespread availability of replacement parts.

The main difference is pump location and operating mechanism. A jet pump sits above ground and draws water from the well via suction, limiting its operating depth to about 25 feet for shallow-well units and 90 feet for deep-well models. Conversely, a submersible pump operates submerged inside the well casing below the water line, pushing water upward through positive pressure. This design offers superior efficiency and eliminates suction-based depth limits. Consequently, drilled wells over 90 feet deep require a submersible pump.

To determine the ideal flow rate, start by checking your well's tested yield, which is the sustainable output measured in gallons per minute (GPM). You can locate this number in your well driller's official report. To prevent severe pump wear and dry running, avoid installing a pump with a GPM rating that surpasses your well's recovery capacity. Standard single-family residences typically require 5 to 10 GPM measured at the pressure switch. Larger demand applications, including multi-unit buildings, high-use households, and lawn irrigation systems, generally necessitate higher capacities of 12 to 20 GPM.

Horsepower requirements are based on your system’s total dynamic head (TDH), which accounts for both vertical lift (the elevation distance from the pump up to the pressure tank) and friction loss throughout the drop pipe and connected fittings. Deeper wells require higher HP ratings to lift water effectively while maintaining the desired pressure and flow rate.

• ½ HP: Suited for standard residential flow demands at moderate operating depths.
• ¾ HP: Provides additional performance headroom for deeper pump settings or extended pipe runs.
• 1½ HP: Designed for high-demand setups that involve substantial depth or higher flow requirements.

If you know your overall well depth, installation setting depth, and required flow rate, give us a call because our team can help you calculate your system's exact TDH.

This is one of the most common sources of confusion when selecting a replacement submersible pump.

• 2-wire pumps have the start and run capacitors built into the motor. They wire directly to the pressure switch without a separate control box, which simplifies installation. However, if the starting components fail, you must pull the entire pump from the well for service.
• 3-wire pumps feature a surface-mounted control box housing the start and run capacitors. Although this adds an extra component, it lets you service or replace the control box, which is the component most susceptible to failure, without removing the pump from the well. For this reason, many professional installers favor 3-wire systems.

If you're replacing an existing pump, the simplest path is to match the wire configuration you're removing. If your current installation has a control box at the surface, you have a 3-wire system. If there is no control box and the wires run directly from the pump to the pressure switch, you have a 2-wire system.

Most residential submersible well pump installations in the northeastern United States run on 230V single-phase power. 230V is more efficient for motor operation at ½ HP and above and is the standard for new well installations. The 115V option in this collection (½ HP, 2-wire) is intended for installations where only 115V service is available at the well. This typically applies to older properties or accessory structures with limited electrical panels. Confirm your available voltage and breaker capacity before ordering.

Only 3-wire models require a separate control box. 2-wire models have the starting components built into the motor and do not need a control box because they wire directly to the pressure switch. If you're selecting a 3-wire pump, the control box must match the pump's HP and voltage rating. We can help you confirm compatibility if you're replacing an existing setup. 

Yes, as long as the pressure tank is properly sized for the pump's flow rate. When replacing a pump, it's a good time to inspect the pressure tank because a waterlogged or undersized tank causes the new pump to short-cycle, shortening its service life. If your tank is more than 10 years old or showing signs of failure (rapid cycling, loss of pressure), replacing the well pressure tank at the same time is worth considering. We also carry tank tee packages with all hardware needed for a complete installation.

All Myers pumps in this collection are 4-inch submersible pumps and require a minimum 4-inch (nominal) well casing. Most residential drilled wells in Connecticut and New England are 6-inch casing, which provides adequate clearance for installation. If you have 4-inch casing, confirm the actual inside diameter with your well driller before ordering because some manufacturers' 4-inch casing runs slightly smaller than nominal.

Yes, these pumps are rated for well water supply and irrigation applications. For dedicated irrigation systems with high demand, the 12 and 20 GPM models at ¾ or 1½ HP provide the flow and head capacity for multi-zone systems. Irrigation typically involves more cycling than household water supply, so proper sizing of both the pump and pressure tank is important for long-term reliability.

A complete submersible pump installation typically includes:

• Drop pipe (poly pipe or galvanized steel) to connect the pump to the surface piping
• Submersible wire rated for the pump's amperage and the depth of the installation
• Pitless adapter to bring the water line through the well casing below the frost line
• Control box (3-wire models only) matched to the pump's HP and voltage
• Pressure tank and tank tee packages
