A pump for boosting and transporting a liquid, includes a housing, a gear rotor device, at least one cover and a motor. A transportation chamber is defined in the housing. An inlet and an outlet are defined in the housing and respectively in communication with the transportation chamber. The gear rotor device is received in the transportation chamber. The gear rotor device includes first and second gears meshing with each other. The at least one cover covers and seals at least one side of the housing. The motor is mounted on one cover with a shaft thereof rotatably connecting with one of the first and second gears. Through a full compression by the gear rotor device, the liquid transportation is in a positive displacement and the liquid is pressurized by the gear rotor device whereby the pump has high head and therefore efficiently transports the liquid.
