  • Advantage of Drilling Rig Components
  • We cooperate with enterprises located in the manufacture basement of oilfield drilling rig components in Western China. Through decades of development and manufacture, there is complete and advanced business system. Therefore, we are provided with low labor cost, rich resource, strong research and development ability, as well as reduced production and transportation cost. Therefore, our drilling rig components have significant competitiveness in price.

    The drilling rig components are the core part of our business. Our partners have many years of manufacture experience. 20 years ago, our partners participated in the outsourcing production of the first drilling pump for the Chinese largest oilfield drilling machinery manufacturer at the time. Based on our long running history and constant technology update, we are the parts supplier for Chinese best oilfield drilling machinery manufacturers.

    1. Mud Agitator

      This impeller-type mixer is mainly applied to mix the drilling fluids, so that to avoid the solids deposit on the bottom of the mud tank and enhance the performance of the drilling fluids.
      The mud agitator, whose power is under 5.5kW, normally adopts cycloidal speed reducer. So the compacted structure brings smaller size. Meanwhile, the driller mixer with over 7.5kW power is fitted with the turbine worm gear reducer, which delivers large torque, stable performance and high reliability.

    1. Mud Pump

      We mainly supply 3NBF series mud pump. This product is horizontal triplex direct drive, and there are many models available such as 3NBF-1300 and 3NBF-1600, etc. The gear shaft is directly driven by this type of motor, avoiding the transmission part in traditional system. So our product has more compacted structure, higher drilling efficiency and less energy consumption.
