A stator for a progressive cavity pump may include a containment element with an inner surface and a casing. The casing may be arranged within the containment element, be generally isolated from the inner surface of the containment element, and define a stator cavity adapted for receiving a progressive cavity pump rotor and for accommodating substantially free rotation of the progressive cavity pump rotor therein.
