1, the use of multi-condition variable parameters, ternary flow technology for design, and flow field analysis and performance prediction. Through the secondary optimization design, the hydraulic parameters of the impeller and the pump body are matched to the best, so that the loss in the pump is minimal and the efficiency is high.

2. Increase the inlet diameter of the impeller and the curvature radius of the front cover of the impeller to improve the anti-cavitation performance of the impeller, and rationally design the suction section to reduce the pressure drop of the inlet part of the pump.

3, the overall horizontal open structure, the import and export are on the pump body, easy to repair and maintenance. The axial structure is compact, the bearing span is small, the shaft stiffness is high, and the pump runs smoothly and reliably.
