The 8PWC350G is a high‑capacity 350 GPM submersible pump, engineered by Caprari using innovative materials and advanced research‑driven manufacturing methods to deliver exceptional reliability, hydraulic performance, and long service life in the most demanding applications.

Designed for very high‑flow and high‑head water systems, this pump is ideal for municipal water supply, industrial process water, and large‑scale infrastructure projects requiring stable performance under continuous‑duty operating conditions. Its optimized hydraulic design supports a wide flow range while maintaining consistent pressure and efficiency.

The pump features heavy‑duty cast iron impellers and smooth, seamless internal hydraulic surfaces, significantly reducing friction losses and ensuring sustained performance over time. An advanced stainless steel core with an improved lip seal design prevents internal liquid recirculation, increasing hydraulic efficiency while allowing easy disassembly for maintenance and servicing.

Enhanced corrosion resistance and early‑stage component passivation protect the pump from the first moments of installation, extending operational life even in harsh environments. Multiple connection options, including threaded couplings and DIN / ANSI flanges, ensure flexibility and easy integration into diverse system designs.
