This invention relates to the field of centrifugal pump technology, specifically disclosing a vertical multistage stainless steel centrifugal pump to solve the problems of how to avoid friction between the impeller and the cavity and poor sealing between multiple impellers; specifically, it includes: a centrifugal pump assembly; the centrifugal pump assembly includes a base, a centrifugal pump housing is installed on the top of the base, a connecting seat is fixed to the outer wall of the centrifugal pump housing, the connecting seat is connected to a motor base located above the centrifugal pump housing via a connecting part, and a motor body is installed on the top of the motor base; this invention abandons the cavity design of traditional vertical multistage stainless steel centrifugal pumps, solving the problems of excessive temperature and wear of the impeller body and inner tank due to friction, thereby improving the working efficiency and service life of the entire centrifugal pump assembly, and the setting of the sealing component can ensure the sealing of the adsorption chamber, thereby ensuring the negative pressure adsorption capacity of the impeller body, and thus ensuring the liquid delivery efficiency of the entire centrifugal pump assembly.
