Grandtech Sand pumps are widely used in solids control systems. It can be placed inside the mud system before the de-sander and mud cleaner to transfer drilling mud to the cyclone unit, which is equipped with the jut mud mixer unit as the mud mixing pump. The sand pump can be used as a trip pump for mud supplement under wells and a supercharging pump to transfer drilling fluids to the high pressure rig mud pump. Sand pump wet contacting parts with excellent wear resistance and high flow rate efficiency are required due to the solids in drilling fluids. Based on the materials used and the structure design.
