BW-160/250/320 mud pump is mainly used for converying mud and water and other flushing fluids in the drilling process and play an important role in the drilling of core, engineering exploration, hydrology and water well, oil and gas well. They can also be used for conveying different liquids in petroleum, chemistry and food processing industries.
