The utility model discloses a vertical multistage wear -resisting submerged pump, including the pump shaft and the pump body, pump shaft upper portion be provided with bearing parts and seal part, thebottom is provided with the middle section to and install in the stator and the impeller of well intersegmental part, balancing sleeve and balance drum are installed to the pump shaft outer wall on middle section upper portion, the impeller be the minor diameter impeller. The less impeller outer diameter of vertical multistage wear -resisting submerged pump, when the transport contains the solidparticle medium, effectual reduction impeller egress line speed, the abrasion speed of particulate medium to flow passage components slows down, flow passage components adopt double shell, adopt highrigidity abrasion -resistant material with the inner housing of particulate medium contact, and outside non - adopts the high strength material with the casing of particulate medium contact, guarantees the bulk strength require
