It offers a maximum shut-off head of 526 feet, making it an effective residential deep well pump. The pump performs optimally in wells where the static water level and lift requirements align with the 10 GPM curve, ensuring adequate pressure for household fixtures.

Common Applications

• Residential potable water supply
• Private wells with 4-inch casing
• Farm and agricultural water needs
• Irrigation systems requiring moderate flow
• Pressure boosting applications
• Cistern water transfer

Important Installation and Use Notes

• This pump requires a compatible control box to operate correctly.

Frequently Asked Questions

Why can’t I see an intake screen on this pump?

The intake screen on Franklin Electric FS Series submersible well pumps is internal, not an external wrap-around screen. This internal design helps protect the pump and supports efficient operation. Because the intake screen is built into the motor bracket, it is not visible from the outside unless the pump is partially disassembled. Please refer to the image below for a visual reference of the internal intake screen’s location.

What is the difference between 2-wire and 3-wire well pumps?

A 2-wire well pump has its starting components built directly into the motor, while a 3-wire pump uses an external control box. The 3-wire design allows easier servicing because the starting components are accessible above ground.

How deep can a 1 HP submersible well pump operate?

This 1 HP submersible well pump has a maximum shut-off head of 526 feet. For efficient household water pressure, it should be installed in wells with operating depths below the maximum lift to maintain consistent flow.

Is the Franklin Electric FS Series pump approved for drinking water?

Yes, the FS Series submersible well pump is NSF/ANSI 61 certified, confirming it is approved for potable drinking water applications.

Does a 3-wire submersible well pump require a control box?

Yes, this is a 3-wire submersible pump, and it requires a compatible Franklin Electric control box to start and operate properly.

What breaker size is recommended for a 1 HP 230V well pump?

Breaker size should be selected based on the motor data plate and local electrical codes. In many installations, a 230V 1 HP well pump typically uses a dedicated 15-amp or 20-amp double-pole breaker.

Is a pump performance curve available for this 10 GPM model?

Yes, detailed pump performance curves are available in the technical documentation. These charts show the relationship between flow rate and head to help ensure proper system sizing.
