A water management system for a hydrogen engine is capable of reducing a capacity of a water tank for storing cooling water injected into the hydrogen engine and is capable of not requiring separate replenishment of water for the water tank. The water management system includes: a water tank module, which stores water for cooling the hydrogen engine; a water pump provided at the water tank module and configured to supply the water stored in the water tank module to the hydrogen engine; and an exhaust line provided between the hydrogen engine and the water tank module and configured to supply an exhaust gas, which contains water vapor discharged from the hydrogen engine, to the water tank module.

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.

A pump module includes: a pump that is installed at the inside of a storage tank in order to discharge a liquid that is stored at the inside of the tank to the outside of the tank; a flange that is coupled to one side of the tank in order to couple the pump to the tank; a heater that is located on the flange so as to enclose a lower portion of the pump; a cover that covers an upper portion of the pump in order to couple the heater to the flange; and a filter that is coupled to the flange so as to enclose the pump, the cover, and the heater and that filters the liquid that is supplied to the pump.
