Abstract
A method of manufacturing a rotor to be used in a dual-rotor lobe pump system for pumping a material at a periodic rate is provided. The method includes selecting a desired periodic flow rate for the material, selecting a number of lobes for the rotor, and selecting either a thickness of the rotor or a spacing between the dual-rotors' axes of rotation in the lobe pump. The method also includes determining the profile for the rotor based on the desired periodic flow rate, so that when the rotor is operated within the dual-rotor lobe pump system, the material can be pumped at substantially the desired periodic flow rate. In another embodiment of the invention, a lobe pump rotor profile is formed by the method described above.
