BWQ-160 mud pump is a horizontal single-cylinder double-acting reciprocating piston pump. The pump adopts a crankshaft connecting rod mechanism, the main transmission system is in a closed state, with good lubrication and high durability. The suction and discharge valves are in the form of ball valves, and the opening and closing of the valves are reliable and durable. The pump has the characteristics of large displacement, moderate pressure, simple structure, easy maintenance, small size and light weight. It is mainly used to supply flushing fluid in engineering geological drilling, and can pump mud pumps with a sand content of less than 5% or other liquids that are not corrosive to metal and rubber parts.
