Franklin FPS-12A-16 is a 2.2kW High Capacity bore pump for irrigation, tank filling and water supply. Pump-end performance is 200L/min at 44m head, before check-valve losses. This version is 400V three phase.
Flow decreases as head increases. The stated flow and head describe the same performance point. Maximum head is the zero-flow value. The performance curve describes the pump end without check-valve losses. Actual delivery depends on pumping lift, required outlet pressure, check-valve losses and pipe resistance. Use the 50Hz performance chart to assess expected flow for the installation. The pump operating range is approximately 60-240L/min, with best efficiency at approximately 110-210L/min.
The outlet is 50mm (2") BSP female thread. An integrated stainless-steel wafer-style non-return valve reduces return flow when the pump stops. These pumps are for bore water with minimal sand or sediment.
400V three phase. Requires a motor starter and motor-overload protection matched to the supplied motor nameplate. This protection cuts power if the motor overloads.
For automatic operation, connect suitable tank-level or pressure controls. Where the bore water level could fall below the pump, use dry-running protection to stop it before it draws in air. Extend the motor lead with correctly sized submersible cable and a waterproof joint for the installation depth.
Install vertically with the motor below the pump, allowing clearance for the pump, cable and pipe connections. Maximum motor submergence is 150m below the water surface. Keep the assembly at least 1.5m above the bore bottom and position it so water passes the motor before entering the pump. Support it with suitable pipework and a safety cable; never lift or suspend it by the electrical cable.
Standard motor application allows water up to 30°C. Higher temperatures require manufacturer assessment of motor loading and cooling. Water must flow around the outside of the motor to remove heat. Fit a flow sleeve where the installation cannot provide the cooling flow required by the motor nameplate, including tank and open-water installations. Keep the complete pump and motor submerged; do not run dry. This motor requires water to pass its outside at least 0.0762m/s (7.62cm/s) for cooling.
The discharge head, outer casing, motor bracket and shaft are stainless steel. Thermoplastic impellers and diffuser assemblies provide the hydraulic stages. Impeller eye and hub seals reduce internal recirculation; a ceramic sleeve and rubber bearing help resist sand wear.
Three-year manufacturer warranty when the FPS4400 pump is coupled to a new Franklin 4-inch motor, subject to Franklin Australia warranty terms, installation-period conditions and applicable consumer rights.
