Franklin Electric Tri-Seal FPS4400 3A Series 304ss 4" Submersible Bore Pumps (Max 60LPM)

The Franklin Electric FPS4400 Tri-Seal 3A Series 4" Submersible Bore Pump delivers reliable water pressure and efficient performance for domestic, agricultural, and light commercial applications. Built with Franklin’s patented Tri-Seal™ floating stage system, the 3A Series is engineered to handle sandy or abrasive water conditions while maintaining excellent efficiency and long-term durability.

Precision-crafted from 304 stainless steel with high-performance thermoplastic components, the FPS4400 3A Series combines strength, corrosion resistance, and superior hydraulic design. Its floating impeller system allows each impeller to move freely to absorb wear and reduce down-thrust, resulting in smoother, quieter operation and extended service life. Ideal for irrigation, stock watering, and bore water supply, the 3A Series provides dependable performance in harsh Australian conditions.
