Franklin Electric Tri-Seal FPS4400 16A Series 304ss 4" Submersible Bore Pumps (Max 400LPM)

The Franklin Electric FPS4400 Tri-Seal 16A Series 4" Submersible Bore Pump is the ultimate high-capacity performer in the Tri-Seal range, delivering exceptional flow, efficiency, and endurance for large-scale water transfer and irrigation systems. Built on Franklin’s proven Tri-Seal™ floating stage system, the 16A Series is designed to withstand the rigours of sandy, abrasive bore water while maintaining reliable, energy-efficient operation.

Manufactured from 304 stainless steel with precision-moulded thermoplastic hydraulics, the FPS4400 16A Series combines strength, corrosion resistance, and superior hydraulic performance. Its floating impeller design reduces down-thrust and wear, ensuring long-term reliability. When paired with a Franklin Electric corrosion-resistant 4" submersible motor, the 16A Series provides powerful and efficient groundwater pumping for agriculture, industry, and large-scale rural water supply systems.
