The BW series mud pump is a horizontal reciprocating double bar double acting piston pump. Used for injecting flushing fluid (mud or clean water) into the hole during geological drilling, in conjunction with large-diameter drilling rigs at depths of 200-600 meters, this pump has a large displacement. High pressure, long service life of vulnerable parts, easy maintenance and repair. In the use of well sites, it can improve drilling efficiency and drilling quality, reduce in hole accidents and drilling costs, and has received high praise from users. It is an ideal drilling equipment.
