Specifications

1. drilling mud pump 3NB650
2. Triplex Single Acting Piston Pump
3. mainly installed on 1500m rig
4. standard type

 The design characteristic is an optimization of parameter. it can increase the stroke properly, lower the speed reasonably, improve the suction capability of the pump, prolong the life of the wearing parts.

The pumps are used for oil-field, other industrial and mining establishments and for the oil drilling, well work over. They are mainly installed on 1500m rig.

The series pump produces according to SY5138 of the petroleum industry standard strictly, and carry through factory's experiment according to the standard.
