A stator for use in a progressive cavity pump is provided, comprising a housing having a suction end and a discharge end, and an elastomeric liner disposed within the housing that defines a passageway for receiving a rotor of the pump. The elastomeric liner comprises a reinforced component that is proximate to the discharge end and that provides a landing surface to resist passage of a rotor head through the passageway.
