<p>A motor pump is disclosed. The motor pump includes a pump body including a casing which is fastened to an inlet case having an inlet port through which inlet water is introduced from a tank by coupling inlet fastening portions to fastening portions, a pumping partition wall disposed inside the casing and having a rotation shaft seating hole formed at its center to form a pumping space between the inlet case and the pumping partition wall, and a discharge port which disch arges pressed water from the pumping space. The motor pump further includes a pumping part including an impeller which is disposed inside the pumping space of the pump body, has a rotation coupling hole formed at its center, and also has impeller wings therein to press the inlet water in the pumping space by rotation, and a rotation part including a rotation case having a rotor at its center, which is fixedly installed on the pumping partition wall while opposite ends of a rotation shaft are supported by shaft supporters such that the rotation shaft coupled to a rotation coupling hole of the impeller of the pumping part is safely inserted into the rotation shaft seating hole, support spacers which are magnets having polarity and are formed on the shaft supporters supporting the rotation shaft toward opposite sides of the rotor, and spacing members which are magnets having the same polarity as the support spacers and are formed at opposite sides of the rotation shaft toward the shaft supporters, wherein an electromagnet is formed at an outside of the rotation case to rotate the rotor with the rotation shaft.</p> |
