Some implementations include an apparatus for washing a downhole tubular. The apparatus may include a head coupled to a rotatable shaft, the head including one or more jets configured to emit fluid to cause the head to rotate on the rotatable shaft and wash the downhole tubular. The apparatus may include one or more brakes coupled with the rotatable shaft and configured to control rotation of the head.

A positive displacement motor (PDM) is provided comprising an outer housing, a thermoplastic stator and a rotor. The PDM may additionally include a mechanism that allows the stator to be removable from the PDM when the PDM is not in operation and resists rotational movement of the stator with reference to a longitudinal axis of the stator and axial movement of the stator along the longitudinal axis of the stator when the PDM is operating, and a rotor disposed within the stator and configured to rotate within the stator when a fluid flows through the stator.
