This is a development designed for the chemical production complex in the pumping medium cyclone pump. Pumping of the pump can contain solid particles or liquid fiber. The design of the cyclone in the analysis has been based on the pump, the improvement of its structure. The pump has excellent performance and reasonable structure, strong corrosion resistance, wear resistance, and load-bearing capacity, and facilitate maintenance, long service life.
The spiral pump using the pressurized water chamber in the pump wear before the front cover plate to increase wear resistance and reduce wear and tear of the main parts to avoid the impact of the pump performance. In order to enhance the efficiency of the pump design uses a two-way tilt of the impeller blades to increase the axial force balance back the leaves, reducing the axial beating. Vice used in the seal on the impeller combined with packing seal. Vice-impeller pump to reduce the pressure chamber to balance the axial force and
