Definition of sand pump. : a pump for removing wet sand, mud, or silt: such as. a : a centrifugal pump used on a floating dredging machine. b : a simple plunger pump with a nonreturn valve at the bottom usually used for cleaning out a borehole.
Sand filters work by allowing water to cycle through a canister that contains sand. The water flows through the sand with ease, but larger particles are unable to pass through. Once the debris and other particles have been filtered out by the sand, a pump moves the clean water back into the pool.
Solids control is a technique used in a drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally, a solid control system contains five stages: the mud tank, shale shaker, vacuum degasser, desander, desilter, and centrifuge.A primary solid-removal equipment should include shale shakers, a degasser, a desander, a desilter, and a decanting centrifuge. All of these parts are installed on top of the mud tanks. As shown in Figure 1.12 (Moore, 1986), the order of operation is shale shakers, degasser, desander, desilter, and centrifuge.
