Drilling Mud Pumps - Mud Pump Manufacturers

What is a drilling mud pump? A drilling mud pump is generally a duplex reciprocating pump (or sometimes a triplex reciprocating pump) used to lubricate the drill bit on an oil field or oil well drilling rig. A solution of bentonite mud is used as the lubricant so drilling mud pumps are sometimes referred to as bentonite mud drilling pumps. Here's a list of manufacturers that manufacture or used to manufacture drilling mud pumps.
