Product Description The DJ surface bumper jar has been proven to be a safe and effective tool in releasing stuck tools in drilling operations throughout the years. It is generally connected at the surface section of the drill string during operations which require strong downward jarring impacts. The jarring force can be easily adjusted with the adjustable device located above the rotary disc. The surface bumper jar is easy to operate and is uniquely designed to support continuous down jarring.Generally when the surface jar makes a jarring operation, the strong down jarring impact on the stuck tool can be clearly seen. Thus, the surface jar is built to withstand heavy load and strong torque. In addition, it possesses good sealing performance that can withstand mud circulation with high pump pressure.Specifications - DJ Surface Bumper JarParameter/ModelDJ46B (4 3/4")DJ70B (7")DJ70C (7")DJ80B (8″)Product Code0208000021300002131000215000O.D.
