Franklin FPS-1A 18 LPM 240V 2-Wire Bore Pump

Franklin FPS-1A 18 LPM 240V 2-Wire Bore Pump

The Franklin Electric FPS-1A is a complete 4-inch submersible bore pump and motor assembly designed for applications requiring moderate water flow at higher pumping heads.

Suitable for domestic water supply, stock watering, tank filling, irrigation and general rural water systems, the FPS-1A range has a nominal duty flow of 18 litres per minute. Four motor and stage configurations are available to suit different bore depths, elevations and pressure requirements.

Available Variants

Increasing the number of stages increases the available pumping head. The correct model must be selected using the required flow and total dynamic head—not bore depth alone.

What Is Included

• Franklin FPS 4400 Tri-Seal pump end

• Franklin 240V single-phase two-wire motor

• Built-in removable spring-loaded check valve

• Four-inch waterproof cable splice kit

• Three-year Franklin Electric warranty, subject to the applicable warranty terms

No separate external starter or motor control box is required for the two-wire motor.

Electrical cable must be sized according to the selected motor, total cable distance, voltage drop and installation conditions. Cable selection and electrical installation must be confirmed by a licensed electrician.

Selecting the Correct Model

Total dynamic head must account for the pumping water level, bore drawdown, vertical elevation, required outlet pressure and friction loss through the pipework and fittings.

The 18 LPM rating identifies the pump family and is not a guaranteed output under every installation condition. Actual performance will depend on the selected model and operating head.

Contact The Pump Shed Australia with your bore depth, pumping water level, elevation, pipe size, pipe length, required flow and required pressure if you need assistance selecting the appropriate model.

How to read the FPS-1A two-wire table: Flow is shown across the top in litres per minute (LPM). Each number in the table is the approximate total head in metres that the listed FPS-1A two-wire model can produce at that flow. Only points inside the blue 11-24 LPM best-efficiency/warranty zone are shown; operation outside this zone is not covered by warranty.
