Abstract
A method for manufacturing a propeller for a propeller pump includes providing a base propeller including a hub extending from an axial end in the axial direction, and a plurality of blades fixedly connected to the hub, each blade including a pressure side, a suction side, a leading edge, an initial trailing edge, and a blade tip extending from the leading edge to the initial trailing edge at the end of the blade facing away from the hub, trimming each of the blades of the base propeller the axial direction, and forming a modified trailing edge bye removing a part of the initial trailing edge along the entire pressure side from the hub to the blade tip.
