Product Details

High-efficiency Impeller

By the CFD* analysis, the flow around the blade surface was optimized. Adopting efficient 4 blade realized pump’s high performance. The invisible water flow inside the pump becomes visible with the analysis using computer simulation. This water flow visualization is the basis of the Impeller geometry optimization. The new highly efficient impeller enables a smooth flow with minimal resistance. This minimizes energy loss, realizing high efficiency.
