Abstract
A fluid driven mud pump with a pump body including a fluid drive cylinder axially aligned with a first mud cylinder and a second mud cylinder. The fluid drive cylinder has a first end, a second end, and a double acting reciprocating piston with a first end of the piston positioned in the first mud cylinder and a second end of the piston positioned in the second mud cylinder. As the first end of the piston forces liquid from the first mud cylinder, liquid is concurrently drawn into the second mud cylinder. As the second end of the piston forces liquid from the second mud cylinder, liquid is concurrently drawn the first mud cylinder. In order to further reduce pressure pulsations a group of pump bodies are formed into a single pumping unit with each of the pump bodies operating out of phase to provide a constant sequential discharge.
