PURPOSE: An underwater axial-flow pump with an anti-vortex head is provided to enable the fluid to smoothly flow since a streamlined head is installed on the rear end of an underwater motor and thus a cross-sectional area gradually decreases. CONSTITUTION: An underwater axial-flow pump with an anti-vortex head comprises an underwater motor(200), an inlet part(300) and a streamlined head(100). The underwater motor generates the torque by the applied power. The inlet part is connected to the front end of the underwater motor. The inlet part comprises a vane and an inlet casing. The vane rotates by the torque from the underwater motor. The vane is installed in the inlet casing. The streamlined head is connected to the rear end of the underwater motor.
