A Moineau style stator includes a helical reinforcement component that provides an internal helical cavity. A resilient liner is deployed on an inner surface of the helical reinforcement component. The helical reinforcement component includes a solder or braze material and is typically metallurgically bonded to an inner wall of a stator tube. In exemplary embodiments, the helical reinforcement component includes a composite mixture of solder and aggregate. Exemplary embodiments of this invention address the heat build up and subsequent elastomer breakdown in the lobes of prior arts stators by providing a helical reinforcement component. Solder reinforced stators tend to be less expensive to fabricate than reinforced stators of the prior art.
