Abstract
A urea solution pump unit includes a bracket mounted to a lower side of a urea solution tank. A pump unit is horizontally disposed at a center of an upper part of the bracket and includes a pump suctioning a urea solution to one direction and a motor pumping the urea solution to another direction through a gap between a rotor and a stator of the motor inside the pump and discharging the urea solution to a lower side of the bracket. A pair of thawing units are fixedly disposed at both sides of the pump unit on the bracket. The thawing units transfer heat to the urea solution and prevent the urea solution from being frozen. A sensor unit is disposed at one side of one of the thawing units and detects a level, a temperature, and a pressure of the urea solution.
