Solids Control

Shear Pump The shear pump is also called shearing pump and mud shear pump, which is a centrifugal pump but used for shearing of drilling mud chemicals, shearing the bentonite. Shear pump KOSUN SP Series  Shear Pump  is mainly used for a quick concoction of high-performance mud so that the time spent on it will be greatly shortened and wells' economic benefits increased. Working Principle; Shear pump  designed to shear of polymer drilling fluid and clay, polymer drilling fluid system (or clay) sufficiently should be cut in advance, and then into the drilling fluid systems, improved drilling fluid properties, can give full play to its effectiveness, if not fully cut polymer loops may plug the vibrating screen for the first time, a significant loss of polymer, increases drilling costs,And may make the bigger solids particles too hard to cuttings ; shear pump can reduce the use of polymer at least 15%, save amount of 30% bentonite, reduce the loss of mud cake and fluid f

Centrifugal Pump Centrifugal pump is a kind of pump to  deliver the liquid by  centrifugal force  generated by  the rotation of the impeller, which  is used for transporting drilling mud. It can be used as feeding pump for desander, desilter,  or as mixing pump for jet mud mixer. The centrifugal pump also called as the  sand pump, it  can also be used as trip pump and supercharging pump for rig mud pump. Centrifugal pump Like most pumps, a centrifugal pump converts rotational energy, often from a motor, to energy in a moving fluid. A portion of the energy goes into kinetic energy of the fluid. Fluid enters axially through eye of the casing, is caught up in the impeller blades, and is whirled tangentially and radially outward until it leaves through all circumferential parts of the impeller into the diffuser part of the casing. The fluid gains both velocity and pressure while passing through the impeller. The doughnut-shaped diffuser, or scroll, the section of the casing dece
