Franklin Electric Tri-Seal FPS4400 2A Series 304ss 4" Submersible Bore Pumps (Max 45LPM)

The Franklin Electric FPS4400 Tri-Seal 2A Series 4" Submersible Bore Pump delivers efficient, reliable, and long-lasting performance for domestic, rural, and light commercial groundwater applications. Built with Franklin’s patented Tri-Seal™ floating stage system, this pump ensures excellent abrasion resistance and consistent operation even in sandy or low-yield wells.

The 2A Series is manufactured from high-grade 304 stainless steel and engineered thermoplastics to maximise durability and hydraulic performance. The unique floating impeller design allows smooth axial movement to minimise wear and thrust load, extending pump life in challenging conditions. When combined with a Franklin Electric corrosion-resistant 4" submersible motor, the FPS4400 2A Series provides quiet, efficient, and dependable operation for bore water, irrigation, and stock supply systems.

FEATURES
