In oilfield, solids control system is the typical 4-stage mud processing system, including shale shaker, desander, desilter, decanter centrifuge. Do you know which pump is used in this system? In each of the complete close loop solids control mud system, there is feeding pump for hydrocyclone separators, the mud transfer pump for charging centrifuge, the drilling fluid mixing pump for configuration, and/or the shearing pump for shredding drilling mud, the trip pump, etc. We also can say, there is horizontal pump, vertical pump, screw pump, etc.

Different equipment request different pumps as power resource or mud supplies. Meanwhile, different solids control system configuration will have different pumps position, design, or types.
 

Usually, the pumps are horizontal one in solids control system. They’ll be mounted on mud tanks' ends or under the slant plate of shaker tank. When we set pumps under shaker tank, it will save much space. However, it will be inconvenient when we repair or inspect pumps.

But sometimes in solids control system there will be vertical pump or submersible slurry pump instead of horizontal pumps.

The centrifugal pumps are always used to transfer drilling fluids for shale shakers, hydrocyclone desander and desilter or mud cleaners. After mud cleaner or hydrocyclone desilter is the 4th solids control equipment-decanter centrifuge. For decanter centrifuge, we need pump to transfer drilling fluid from desilter compartment to centrifuge input. We usually use the screw pump or submersible slurry pump to feed it.

As a professional manufacturer, KOSUN has been providing the drilling fluid solids control equipment and solids control system for more than 20 years, main 5 stage solids control equipment include the shale shaker, desander, desilter, vacuum degasser, drilling fluids mud cleaner, decanter centrifuge, other mud pumps and mud tanks.
