Abstract

This utility model discloses a vertical water pump, comprising a pump body with an inlet at the bottom and an outlet at the top, and a water passage connecting the inlet and the outlet; a stator disposed within the pump body; a rotor disposed within the pump body; an impeller disposed on the rotor; and a check valve disposed within the pump body to restrict water flow from the inlet. This utility model provides a vertical water pump that integrates the check valve inside the pump body, achieving integrated check valve functionality, eliminating the need for an external check valve, making the entire vertical water pump compact, easy to install, and reducing potential leakage points caused by external pipe fittings, thus improving reliability and sealing.
