To solve problems in a conventional automatic pump device that an installation area must be secured and introduction of expensive equipment is needed, as chemical must be injected into water pumped up by a conventional automatic pump device, by an automatic sterilization device, that is, the automatic pump device and the automatic sterilization device are needed.
A pump device capable of sterilizing drinking water by including a suction port for sucking water, a motor for rotation-driving an impeller, a pressure tank for storing the water sucked from the suction port by rotating the impeller, a discharge port for discharging the water stored in the pressure tank, an ultraviolet ray sterilization device for irradiating ultraviolet rays to flowing water, and a controller for controlling the motor and the ultraviolet ray sterilization device, is provided to solve problems.
