The invention may utilize shaft horsepower for rotating cylinders to move a fluid in an axial direction within the cylinder. The cylinder may comprise a spiral blade on or in its inner surface with a pitch relative to a central axis of the cylinder. The blade's pitch may be variable or uniform with respect to the central axis. In some applications, plural blades may be positioned within the cylinder. The invention is particularly suitable for imparting kinetic energy sufficient to assist with the evacuation of condensate from a paper dryer cylinder with reduced or no blow through steam. The invention also has applications for spinner wheels.
