Franklin FPS-1A 18 LPM 415V Three-Phase Bore Pump – Complete Pump & Motor

The Franklin Electric FPS-1A is a complete 4-inch submersible bore pump and three-phase 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. Five motor and stage configurations are available to suit different pumping heads 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 400/415V three-phase submersible motor

• Built-in removable spring-loaded check valve

• Four-inch waterproof cable splice kit

The starter, protection equipment and electrical cable must be selected to match the chosen motor. Cable sizing must account for the total cable distance, voltage drop and installation conditions.

Electrical installation must be completed 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 depends on the selected model and operating head.

FPS-1A - 18 LPM Range

How to read the FPS-1A 415V 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 three-phase 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.
