NBQ25-380 skid-mounted pump

NBQ25-380 skid-mounted mud pump serves as a matched equipment both shallow well rig in the oilfield.

      The light duty triplex mud pumps, such as NBQ25-380 have won the favor of users with the advantages of light weight and convenient transportation by single truck. These equipments, sold to many large oilfields and Southeast Asia markets in batches, are the best pumps for light-duty drilling rigs and workover rigs. Quintaplex mud pump with high performance includes NBQ35-800, NBQ35-1000 and NBQ35-1300. These are mainly used for circulating operation for intermediate and shallow well drilling and directional drilling operations. The power and operation system feature compact arrangement, small floor space, and convenient transportation, which is the optimized choice for drilling service of intermediate and shallow wells.
