<p>PROBLEM TO BE SOLVED: To provide a motor pump which utilizes a liquid fed by a feeding member to cool an armature stator, has simple structure, and prevents the deterioration of the motor efficiency without causing the size increase.SOLUTION: A canned motor pump 2 includes: a rotor housing 10 which is provided so as to cover a rotor 8 and seals the rotor 8 in a fluid-tight manner; a stator housing 11 which is provided so as to cover an armature stator 9 and seals the armature stator 9 in the fluid-tight manner; and a motor housing 12 which is attached to an outer periphery part of the stator housing 11 so as to hold the stator housing 11 and forms a liquid passage 17 communicating with a liquid introduction port 7A and a liquid discharge port 7B with a body case 7. The motor housing 12 includes: an opening part 12B communicating with the stator housing 11; and a support piece 12C fixed to an inner peripheral surface of the body case 7. Impellers 6A, 6B are provided at the liquid discharge port 7B.</p> |
