A progressing cavity pump (PCP) system that may be deployed in an existing well configuration without the need for a workover rig. A stator and tubing stop are first set in a conduit, such as production tubing, at a desired depth. In subsequent wireline runs, a pack-off and upper tubing stop are installed above the stator, which results in the stator assembly being set by tubing stops on top and bottom and results in the conduit above the PCP being isolated from the wellbore below. Installation of the system is completed by installing the rotor and by installing top-side drive equipment in the usual way. The PCP system allows the deployment of lift systems within existing well configurations without any element being deployed on tubing and provides the ability to retrofit a well with an insertable pump within existing tubing.
