Abstract
A free-mold stator for a progressing cavity pump can comprise a housing include an inner housing surface defining an uninterrupted helical profile, and a liner including an inner liner surface and an outer liner surface. The inner liner surface and the outer liner surface can each define an uninterrupted helical profile, and the inner housing surface of the housing can be adapted to receive the outer liner surface to prevent lateral and rotational movement between the liner and the housing.
