The Type "S" Stop Turn Anchor is primarily designed to prevent tubing from backing off or to tighten a string of tubing that has been in the well. It is usually run with positive displacement "screw pumps".
OPERATION:
Set:
The tubing is turned to the right, moving the rocker drag slip and forcing the wicker side of the rocker drag slip into the casing, preventing the tubing from turning.
Release:
The Type "S" Stop Turn Anchor is turned in the opposite direction that was used to set the pump anchor.
FEATURES:
- Compact, beneficial for gas by-pass
- Rocker drag slip for setting and releasing control
- Complete lock system
