Abstract This article focuses on the following problems which shorten the pump′s life: the poor ability of the movable and vertical pump against the erosion,the serious erosion of the flow passing parts,the untimely and frequent damage of the seal. These problems are analyzed from the design of hydraulics and structure,selecting of materials,surface hardened of the flow passing part,achieving the points what need be pay attention to in the design and the practical way in surface hardening and seal of the structure.
