Abstract
An electric motor pump with axial-flow impellers includes an electric motor having an output shaft both end portions of which are connected to axial-flow impeller units, and a pair of pump housings provided on both sides of the motor in the longitudinal direction of the output shaft and including fluid inlet and outlet ports, the pump housings cooperating with the impeller units to suck fluid into the housings through the inlet ports, move the fluid in the longitudinal direction and discharge the fluid from the outlet ports, thrust forces applied to the output shaft by the impeller units are canceled.
