BW-200II mud pump is a horizontal double-acting reciprocating duplex piston pump.It is mainly used for feeding flushing fluid to well drilling. It is lightweight, compact and is more suitable used In geological prospect.To meet diamond drilling, BW-200 mud pump is fixed two-kind-diameter cylinder liner Φ80mm and Φ65mm.
when the hole depth is 600m, we can use cylinder liner of Φ80mm.When the hole is 1000m, we use cylinder liner of 65mm.
