Reverse Circulation Junk Basket
The reverse circulation junk basket is used to retrieve all types of small junk objects in well bores. Such as bit cones, cutting blades and hand tools, etc..
During operation, with the steel ball dropped into the valve seat, fluid flow in a continuous stream to the center of the tool and up through return ports in the upper end of the barrel, all junk is thus carried into the barrel above the junk catcher.
