A progressive cavity pump capable of operating at both high and low system pressures. The pump includes a housing with an elastomeric stator disposed therein. A rotor is rotatably and pumpingly disposed in a pumping chamber defined by the stator. A support member is disposed annularly between inner and outer portions of the stator, and the member bears longitudinally against an annular end portion of the stator and a facing annular shoulder in the housing such that deformation of the stator is prevented when high inlet pressures are present.
