BW-350 mud pump is a horizontal, triplex, single acting reciprocation piston pump. This pump can also be used as a mud-pump cooperating hydrology sand well drilling machines and 100m car drilling machine, or be used as a injection pump which is used to affuse cement slurry into softground. It has four shifts of flow rates and four shifts of pressures. Comparing to some other pump with same specifications, it has advantages such as smooth rotation, large-scale variable rates of flow, high out-but pressures, longer service life of the wearing parts and steady performance, etc.

BW-350 mud pump is an improved type of BW-250 pump. A majority of their parts are common parts, so the structure, operation of the pump, disassembly and assembly the pump, lubrication of the pump,trouble shooting guide of the pump and prevention check are the same with the BW-250 pump.
