Mud pump has a longer stroke and can be operated at a lower stroke, thus improved the water supplying perfor-mance effectively and extended the lifetime of expendable parts in the fluid end greatly.
The power end uses combined lubricating system of forced lubrication and splash lubrication. Reliable to lubricate and promote the service life of power end.
This series mud pump are strictly manufactured according to API Spec 7k "the Equipment Specification of Well Drilling and Repairing", and are tested accordingly when leave factory.
Features of drilling rig mud pump
1. The pump has features of advanced structure, small volume, reliable operation, easy maintenance.
2. The cylinder is made of alloy steel forgings, and the three cylinders of each pump are interchangeable.
3. In order to enhance its corrosion resistance, the cylinder surface is processed by chemical nickel plating.
4. The design of straight-through cylinder valve structure, reduced the volume of the hydraulic cylinder and increased the volumetric efficiency.
