The 6PWC325G is a heavy‑duty 325 GPM submersible pump, engineered by Caprari using innovative materials and advanced research‑driven manufacturing processes to deliver exceptional reliability, hydraulic efficiency, and long‑term performance in high‑demand applications.

Designed for high‑flow water supply and industrial systems, this submersible pump supports a wide operating range while maintaining stable pressure and consistent flow. Its robust hydraulic design makes it ideal for municipal infrastructure, industrial process water, and large‑scale commercial installations operating under continuous‑duty conditions.

The pump features strong cast iron impellers combined with smooth, seamless internal surfaces, reducing hydraulic resistance and ensuring sustained efficiency over time. An advanced stainless steel core with optimized lip seal design prevents internal liquid recirculation, improving overall performance while allowing easy disassembly for inspection and maintenance.

Enhanced corrosion resistance and early component passivation protect the pump from the first moments of installation, significantly extending service life. Multiple connection options, including threaded couplings and DIN / ANSI flanges, ensure flexibility for integration into a wide variety of system layouts.
