Mechanical Junk Basket PM

Application

The Mechanical Junk Basket PM is designed to retrieve different metal pieces (rolling cones and bearings of drilling bits, cutter arms, cable pieces, metal fragments which have appeared after milling process, etc.) from bottom hole.

Design

The Mechanical Junk Basket consists of tubular body (made of high-strength alloyed steel), sub, two mechanical petal type catchers and washover shoe.
Catchers are set at lower part of body in two levels with possibility of free rotation.
The catcher is equipped with interlaced and extended to the center of tool short and long pins. This tool operates as float valve. The catcher lets core sampler and small metal pieces in one direction (into the tool) by deviation of spring-loaded joint pins upwards. It doesn’t transmit captured pieces in reverse direction (from the tool).
The Mechanical Junk Basket can be designed in left/right configuration depending on direction of connection threads.
