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 design helps protect the pump and maintain efficient operation. Because the intake screen is built into the pump’s internal motor bracket, it is not visible from the outside unless the pump is partially disassembled.

What is the main advantage of a floating stage design?

The floating stage design improves efficiency and minimizes wear from abrasives by reducing downthrust on the motor, which helps extend the pump’s operational life.

Is this a complete kit?

No. This product includes the Franklin Electric submersible well pump and motor only. The required 3-wire control box is sold separately.

Can this pump be used for a new well installation?

Yes. This 1/2 HP submersible well pump is well-suited for new residential well installations and is commonly paired with pitless adapters for a frost-proof connection.

What does NSF 61 certification mean?

NSF 61 certification confirms that the pump is safe for use in potable drinking water systems and that no harmful substances leach into the water supply.

What are the voltage requirements for this pump?

This is a single-phase 230V submersible pump. The supplied voltage must remain within ±10% of the rated voltage for proper and safe operation.

How does a VFD (Variable Frequency Drive) benefit my system?

A VFD automatically adjusts pump speed to maintain constant water pressure, improving energy efficiency and delivering a more consistent water supply throughout the home.
