    Abstract: An anti-rotation device for and method of preventing rotation of alternate deployable electrical submersible pumps (ESP's) within a well casing. This anti-rotation device includes a mandrel connected with the ESP (or ESP string) and a torque anchor connected with an inner surface of the well casing. A portion of the mandrel is configured to engage an inner surface of the torque anchor is such a manner as to prevent rotational movement of the mandrel (and ESP) within the well casing. The mandrel may be of variable length and configured to allow variable and selective positioning of the ESP within the well casing. The interaction of the mandrel and the torque break also provides for alignment of the ESP within the well casing. Additionally, it absorbs and dissipates pump induced torque for the ESP.
