Core drilling is an important technique for the exploration of minerals, oil and gas reserves, geological surveys, and construction and engineering projects such as dams, tunnels, and bridges. Core drilling machine is a kind of geological core drilling equipment, which is mainly used for the survey and exploration of metal and non-metallic solid minerals. It can also be used in engineering geological exploration, hydrogeological survey, survey and exploration of oil and gas fields, and drilling. The core drilling machine has three different technical characteristics of mechanical vertical shaft type, full hydraulic and electric top drive type. 

A mud pump for core drilling is a specialized type of pump that is used to circulate drilling fluid (mud) through the drill string and out through the drill bit to facilitate the core drilling process. The mud pump creates pressure to circulate the drilling fluid down the drill pipe and then back up to the surface along the outside of the drill string, carrying the drill cuttings out of the borehole.

Mud pumps for core drilling typically use positive displacement technology, which involves a set of pistons or gears that rotate and reciprocate to create a constant flow of mud. The mud is then pumped under high pressure and volume, which helps to remove cuttings and cool the drill bit, reducing friction and heat produced during the drilling process.

Mud pumps for core drilling are available in a variety of sizes and capacities, depending on the size of the borehole, the depth of the drilling, and the specific requirements of the project. They are designed to be rugged and durable, capable of withstanding harsh drilling conditions and prolonged use. Proper maintenance, repair, and replacement of parts such as liners, pistons, valves, and seals are essential to keeping the mud pump operating effectively and efficiently.
