Centrifugal pumps are also called the mud pumps in some places, and it is really a common and efficient solution for transferring the drilling mud. In a complete mud recycling system for drilling rigs, there are different models of centrifugal pumps to be used, for following functions, let’s count them from the first tank:

1. In a trip tank, normally a small centrifugal pump is used as trip pump. It is used to suck mud from the trip tank to the well mouth when the mud from the solids control system is not enough.

2. In the shaker tank, always installed below the shaker’s sand trap, there are centrifugal pumps which are used to feed the desander cones and desilter cones after the shaker. Those pumps’ size are decided by the requested treating capacity of the complete system.

3. Mud mixing unit uses centrifugal pumps as mixing pump. Normally there is a separate skid for mixing with hoppers to be mounted together, or an extended skid of tank for mounting the 2 parallel installed centrifugal pumps. Those pumps are serving same function with same piping work, one is in use while the other is backup. By opening and closing the correspondent valves, the pipeline could be connected to each tank, including storage tank and mixing tanks.

4. Charging pumps are also centrifugal pumps, which are connected to the mud recycling system but outside in position.

GN has been building centrifugal pumps for many years, and recently GN just upgraded the material for the centrifugal pumps. In both outer dimensions and inner parts, all are interchangeable with Mission pump. For this order, for Venezuela, which the customer purchased are the newest models of GNSB series centrifugal pumps.
