Abstract
A scroll pump facilitates the installation of a new tip seal between an axial end of the scroll blade of one of inner stationary and orbiting plate scrolls of the pump and the plate of the other of the inner stationary plate and orbiting plate scrolls. To this end, the orbiting plate scroll has a central portion and an outer peripheral portion extending around and seated on the central portion. The outer peripheral portion of the orbiting plate scroll is keyed to and/or fastened to the central portion such that the outer peripheral portion is not rotatable relative to the central portion and yet is axially removable from the central portion. The tip seal can be readily accessed and replaced by removing the outer peripheral portion of the orbiting scroll plate from the central portion.
