PURPOSE: A water pump for coolant transportation in low and high temperature circulation systems is provided to remove the heat transfer from high temperature circulation system to the low temperature circulation system. CONSTITUTION: A water pump for coolant transportation in low and high temperature circulation systems comprises a low temperature housing(2), a first installation surface(4), a high temperature housing(5), a second installation surface(7), a water pump rotor(8), and a drive shaft(9). The low temperature housing comprises a low temperature spiral(3) inside. The high temperature housing comprises a high temperature spiral(6) inside. The water pump rotor transfers coolant in the low temperature spiral and the high temperature spiral at the same time. The drive shaft drives the water pump rotor. When the water pump is completed, the first installation surface contacts the second installation surface under the intermediate connection of a heat insulator(10). The two installation surfaces are located between the low temperature spiral and the high temperature spiral to form a first plane(E1).
