QZ3NB-800 drilling mud pump is the pump that researched and manufactureed by Qingzhou petroleum machinery factory . The design characteristics is an optimization parameter, it can increase the stroke properly, lower the speed reasonably, improve the suction capability of the pump, prolong the service life of wearing parts .The pump is used for oil-field and other industrial and mining establishments,and also used for the drilling, well workover and transporting the liquid media. It is mainly installed on 2000m rig.
The series are produced according to SY5138 of the petroleum industry standard strictly.
