[0002] Industrial centrifugal pumps are a type of fluid conveying equipment widely used in the chemical industry. They operate by using the centrifugal force generated by the rotation of the impeller to draw fluid in through the center of the impeller. The fluid is then ejected at high speed along the impeller's tangent, entering the pump's volute or guide vanes. Within the volute or guide vanes, the fluid's velocity gradually decreases, while its pressure gradually increases, before being discharged from the pump's outlet.

[0003] Due to the special nature of the liquid transported in the chemical industry, leakage is prone to occur at the inlet and outlet connections of the pump body under the erosion of long-term corrosive liquids. Since chemical liquids are mostly difficult to clean, it brings inconvenience to use. Therefore, we propose a chemical centrifugal pump body to solve the above problems. Utility Model Content
