The utility model discloses a vertical multistage feed pump in the technical field of water pumps, which comprises a water suction pump, the lower end of the water suction pump is in threaded connection with a flow passage component pipe, the lower end of the flow passage component pipe is in threaded connection with a filter box, the inside of the filter box is rotatably connected with a filter assembly, and the filter assembly comprises a rotating baffle and filter holes. The rotating shaft is arranged on the rotating sleeve. The device has the effect of relieving the impact force of water flow, the rotating sleeve rotates and relieves the impact force, meanwhile, the flowing speed of water is increased, the water pumping effect can be better, filtered impurities are rotated into the s-shaped groove of the rotating baffle through the eccentricity effect, the cleaning effect is achieved, and the device is simple and convenient, does not need manual operation and saves time and labor. 本实用新型公开了水泵技术领域的一种立式多级给水泵
