4.Working Principle

Increase tubing hydraulic pressure, the grips get out and occlusion with casing, realize anchoring. When the tubing liquid pressure disappear, the grips get back and release under the action of spring force.

5.Product Feature

●Simple, convenient.

●High strength alloy steel, high performance.

●Adopt high elasticity stainless steel spring, stable performance.

●Stable start pressure, easy release, anchor reliably.

●Non-metal hydraulic anchor is our patent product, it adopt non-metal anchor claw to avoid the movement of string and protect casing from damage.
