In drilling fluid solids control system, centrifugal pumps are always used to transfer drilling fluid for shale shakers,hydrocyclone desander and desilter or mud cleaners.
Drilling fluid solids control system

Drilling fluid solids control system is the typical 4 phase mud process system，including shale shaker, desander, desilter, centrifuge.The shale shaker is the first stage of solids control equipment in solids control system, which removes cuttings with diameter above 75μm from the drilling fluids brought up from the wells.Drilling mud desander is the second stage of solids control equipment in solids control system. It is mainly used to take away the solids with diameter ranging from 45 to 74 μm from the formerly treated fluids.Desilter is the third stage of solids control equipment in solids control system. Decanter centrifuge is the solids control equipment which used to separate the solids from volumes of liquid that contain solid particles.

Centrifugal pump used as mud pump

KOSUN CP Series centrifugal pump is used for transporting drilling mud. It can be used as feeding pump for desander, desilter, or used as mixing pump for Jet Mud Mixer. Also it can be used as trip pump and supercharging pump for rig mud pump.Usually, these pumps are horizontal one. They’ll be mounted on mud tanks ends or under the slant plate of shaker tank. When we set pumps under shaker tank will save much space. However, then 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.
Drilling fluids flow into the shale shaker directly after it returns to the surface of the well, and the solids that are removed by the screen would be dischanged out of the tank, and the drilling fluids with smaller solids would flow through the screen into mud tank for further purification. A centrifugal pump would sucks the shaker-treated fluids up to the desilter or mud cleaner for further purification. And vertical slurry pump is used to pump the drilling fluids up to the centrifuge,and mud pump would pump the drilling fluids from mud tank into the borehole after it is treated by centrifuge.
