Franklin Electric Tri-Seal FPS4400 9A Series 304ss 4" Submersible Bore Pumps (Max 210LPM)

The Franklin Electric FPS4400 Tri-Seal 9A Series 4" Submersible Bore Pump delivers exceptional flow capacity, reliability, and long service life for demanding domestic, agricultural, and commercial water systems. Built with Franklin’s patented Tri-Seal™ floating stage system, the 9A Series ensures superior sand-handling, efficient performance, and protection against wear in abrasive groundwater environments.

Constructed from 304 stainless steel and engineered thermoplastics, the FPS4400 9A Series is corrosion-resistant and built to last. The precision-moulded floating impellers and modified PPO diffusers maintain smooth hydraulic efficiency, while the spring-loaded check valve prevents backflow for dependable operation. When paired with a Franklin 4" corrosion-resistant submersible motor, the 9A Series provides reliable, energy-efficient water delivery for large domestic systems, irrigation networks, and light industrial installations.
