Rotary Mud Drilling
This drilling method (with mud pump for flushing) can be direct circulation and reverse circulation, with tricone bit, drag bit and etc. Nevertheless, the torque is relatively critical for this drilling method. It is widely used in soft to medium hard ground conditions.
The high torque feature from our hydraulic rotators, together with the good power to weight ratio, makes the whole range of HD drill rigs (product range) suitable for all kinds of rotary mud drilling,. Besides, the HD mud pump (such as GP500) can be mounted on the drill rig for rotary mud drilling.
