Mud Pumps

A mud pump is a piece of equipment for transporting heavy mud and other dense fluids in wells and other industrial applications. The well pump’s main function is pumping mud from the well bore to the well bottom so as to cool drills, wash away drill cuttings and maintain the well stability. The mud pump is thus considered as the core of a drilling system.

Features Able to create high pressures to pump large flows Various pump structures to adapt to different oilfields Reliable operation and a long service life Applications Oil drilling: used to pump heavy mud to lubricate the drill and the well wall and clean drill cuttings Mining: used to pump dense materials like coal gangue and ores Construction: used to pump cement mud, mortar and other construction materials Chemical industry: used to pump dense chemicals Technical Parameters
