High Quality Investment Casting Vertical Turbine Pump Bowl Impeller

The swirl impeller is all or part of the impeller is retracted to the flow channel of the pressure chamber, and has good anti-clogging performance. The particles flow in the water pressure chamber is driven by the eddy current generated by the rotation of the impeller. The movement of the suspended particles does not generate energy, and the flow channel exchanges energy with the liquid. In the flow process, suspended particles or long fibers do not contact with the worn blades, and the blades are slightly worn, and there is no increase in clearance due to abrasion, which is suitable for pumping media containing large particles and long fibers.
