Torque anchor is used to take the reactive torque given by the friction created between the rotor and stator of the pump with progressive cavities, to prevent the tubing from unscrewing. It is mounted under or just above the pump. It uses the principle of a mandrel with two slips (one floating,one stationary) camming in opposite directions anchoring the tubing string to the inner casing wall.
