Franklin Electric Tri-Seal FPS4400 12A Series 304ss 4" Submersible Bore Pumps (Max 280LPM)

The Franklin Electric FPS4400 Tri-Seal 12A Series 4" Submersible Bore Pump delivers exceptional flow capacity, efficiency, and reliability for heavy-duty groundwater pumping applications. Designed with Franklin’s patented Tri-Seal™ floating stage system, the 12A Series ensures superior sand-handling performance and protection against abrasive wear, providing smooth operation and extended service life in harsh bore water environments.

Constructed from 304 stainless steel with precision-engineered thermoplastic components, the 12A Series is corrosion-resistant and built for long-term durability. The floating impeller design reduces axial load and improves hydraulic efficiency, while the spring-loaded check valve provides reliable backflow prevention. When combined with a Franklin Electric corrosion-resistant 4" submersible motor, this pump system delivers high-performance water delivery for large domestic, agricultural, and commercial installations.
