Mud Pump

Horizontal,3-cylinder,single-functional reciprocating piston pump. The speed-change device can make drilling mud pump convey flow at 3 different levels. Simple and compact design, lower weight, smaller size, easy for maintenance and repair, disassembly, installation and movement.

Operation Panel

Optimized Simply and compact design, easy for operation and maintenance, less problems, more reliable. Drilling speed, water pressure, oil pressure are centrally realized on the panel. Easy for rod feeding, rod withdraw and all the operations on site.

Outstanding features:
Unmatched high drill head and spindle speed, which allows high drilling speed
Full hydraulic driven and control system, including:
     Hydraulic rod feeding, pushing and pulling system;
      Hydraulic rod rotation driving system;
Superior quality key components made of aircraft grade materials, fabricated with 
   professional aircraft industry machinery;

Power supply can be made by electrical motor/generator assembly.
Drilling angle adjustable between 0°and 360°
Advanced winching system 

Flexible rotation base frame. Designed  for easy change the direction by turning the base by losing the bolts but no need to change the cylinder direction.

Secondary hydraulic oil filter. to make the filtration for hydraulic oil more safe, we set up the secondary filter in the chuck which will shows as a red point.

Magnetic prevention for hydraulic oil. Even if we have the first stage filtration for hydraulic oil from the oil tank, but we also set up the strong magnetic on the tank to absorb any chips so as to avoid it goes to next step.

Oil temperature sensor. In order to keep the temperature of hydraulic oil at safe level, we configures with the temperature sensor in the flow to monitor and feedback during the work.

Electrical work time meter. We configure with this electrical recorder so that there will be clear record and report to check how much work has been done.

More advanced, more humanized, more optimized design for whole working system.
