DRAG BLOCK TUBING ANCHOR/CATCHER
The Drag Block Tubing Anchor/Catcher (DB Anchor) is a retrievable positive-action tubing anchor designed to hold the tubing string in tension or compression. It has drag blocks to allow the anchor to be run deeper than conventional drag spring anchors. The anchor prevents movement of the tubing during pumping strokes; and holds it stationary if it should part. The use of a tension tubing anchor increases pump efficiency, reduces rod and tubing wear, and keeps tubing and rods from falling into the well in case of a part.
Features:
- Enclosed slips
- Rotational release or shear release
