<p>The purpose of the present invention is to provide a pump for a boiler which enables reduction in manufacturing costs and improvement of installation and replacement workability by reducing the number of parts of the pump for a boiler and simplifying the coupling structure between the parts. To achieve this purpose, the present invention comprises: a head having an inlet and an outlet for passing heating water therethrough, and an impeller for transferring the heating water introduced through the inlet to the outlet; a motor housing connected to the head and having a shaft axially connected to the impeller, a rotor fixed to the shaft, and a stator provided on the periphery of the rotor so as to rotate the rotor using a magnetic field generated by an applied electric current; and a division housing, provided between the head and the motor housing, for preventing the heating water passing through the inside of the head from being introduced to the motor housing, wherein the motor housing comprises a first motor housing and a second motor housing, and the division housing and the first motor housing are formed into an integral frame.</p> |
