Solids Control System

  Hydrocyclones for Desander, Desilter and How to Choose Sand and drilled solids can quickly build up in a drilling fluid system if they are not removed at the right stage. Coarse sand is usually handled by a desander, while finer drilled solids may need a desilter further downstream. Both machines use hydrocyclones, but they are designed for different parts of the solids load. Desanders normally use larger cones for coarse solids, while desilters use smaller cones for finer solids. When selecting hydrocyclones for solids control , the practical questions are simple: What solids need to be removed? How much mud needs to be processed? What are the mud conditions, and what pressure is available at the cyclone inlet? Hydrocyclones for Solids Control The Difference Starts With the Solids A desander is generally installed downstream of the shale shaker. The shaker removes the larger cuttings first, and the desander takes out sand-sized material that remains in the mud. A desilter ...

 Two pump names cause more confusion on industrial sites than they should: the vertical slurry pump and the submersible pump. They sound alike, they are both vertical, and they both move abrasive, solids-heavy slurry. The difference lies in how far each one sits in the liquid and what that does to the motor and the mounting. This piece covers what each pump is, where they differ in practice, and how to pick the one that fits your pit or process. Cutaway diagram of a vertical slurry pump with the motor above the liquid line and a submersible pump with the sealed motor below the surface YZ  Vertical Submersible Slurry Pump The Vertical Slurry Pump (Under-Liquid, Cantilever Type) A vertical slurry pump, sometimes listed as a vertical submersible slurry pump, puts only the pump head below the surface. The vertical motor sits on a support frame above the liquid and drives the pump shaft through a coupling, so the power train stays dry. The benefit of that layout is how little t...
