Title: Flexible tube pump

Abstract: A flexible tube pump comprises motor means having mounting elements on the casing thereof and a rotatable shaft. A rotor is carried by the shaft and impeller elements are distributed circumferentially on the rotor to orbit as the rotor rotates. A substantially U-shaped shield has leg means securable to the motor casing mounting elements and a semicircular bight portion cantilevered from the leg means substantially concentrically of the orbit of the impeller elements. A compressible tube is engagable between the shield and orbiting impeller elements. A housing may enclose the motor, rotor and shield, the motor being fixed to a cover on the housing and end portions of the tube extending out through a wall of the housing.
