Abstract: A driveshaft (401) for driving a rotor of a positive displacement pump has an axis of rotation (410) and a plurality of flat surfaces (412) arranged symmetrically around and substantially parallel to it. There are also a plurality of cylindrical surfaces (414) arranged around the axis of rotation and extending between adjacent flat surfaces (412). A length of the flat surfaces (412) in a direction parallel to the axis of rotation (410) is greater than a length of the cylindrical surfaces (414) in a direction parallel to the axis of rotation.
