Dynamic anchor

The dynamic anchor compensates for the reactive torque created by friction between the rotor and stator of an eccentric screw pump and prevents the tubing hanger from unraveling. The dynamic anchor mounts under the pump.

 The bearing bars are constantly under pressure and are in contact with the casing wall of the well due to helicoidal springs. The pumped oil passes through the central hollow body with cam washers attached to it.

Dynamic anchor is brought into operating position by clockwise rotation of tubing string. At the same time, the anchor working bars make firm contact with the inner wall of the production string.

The manufactured products meet the required technical requirements and standards.
