SUBMERGED MOTOR PUMP

摘要

PROBLEM TO BE SOLVED: To provide a submerged motor pump capable of using different materials for a pump shaft and a motor shaft and integrally connecting the pump shaft to the motor shaft without using a connecting member such as a coupling. SOLUTION: This motor pump connects a pump part P to a motor part M in series and is used in water or in liquid. A main shaft 66 is so constituted that a pump shaft 10 or an axis disposed inside the pump part P and integrally rotating with impellers 12a-12e, is fitted to a pump side end part of a hollow motor shaft 30 disposed inside the motor part M and integrally rotating with the rotor 32.
