An insertable progressing cavity pump is taught. The pump is insertable in a bore of a tubing string by carriage on a drive string, the insertable progressing cavity pump includes a stator, a helical rotor locatable in the stator and including a coupling for connection to the drive string, a tubular housing for accommodating the stator therein and sized to be insertable into the tubing string, a pump hold-down arrangement in communication with the housing and disposed above the stator for engaging the pump into the tubing string, and a torque transmitting arrangement acting between the rotor and the housing to transmit torque from the rotor to the housing in both the clockwise and counter-clockwise direction, when the housing is carried on the drive string. The insertable progressing cavity pump in another aspect includes a hold down assembly disposed above the stator on the pump housing.
