Mud Saver/ Mud Bucket

Mud Saver or mud bucket is designed for drilling fluid recovery, and can fit pipe sizes from 2⅜" to 6⅝".

With the conventional drilling mud box, some mud is lost over the bell nipple or onto the rotary table and floor when pulling wet strings. Mud Saver catches and returns this fluid to the active mud system or trip tank.

Mud Savers or Mud Buckets feature a quick-opening and closing latch assembly, which provide efficient, positive, and convenient means of keeping rig floors dry and safe. Cuts labor cost in wash down time on rig floors.

Mud-Saver also prevents the loss of drilling fluids and spillage onto rig floors, reducing the risk of accidental polluting when drilling in environmentally sensitive areas. Mud-Saver also improves operations safety by preventing slick floors that can lead to crew accidents. Eliminating drill spillage onto the rig floor also reduces crew clean-up time and cuts wash-water disposal volumes. In addition, it allows more precise monitoring of hole-fill volume, thus providing superior pressure control.

Locking drive pins are optional. The expendable wear guide rings made of copper are for pipe sized for 3½"~5" and 5½"~6⅝".
