RL3NB-350 Triplex Single-Acting Back and Forth Piston Pumps

  The design characteristic of 3NB-350 Triplex Single-Acting Piston Pump is the optimum parameter,appropriately increasing stroke,reasonable lower stroke number to improve the functions of pump suction. And ,it extends the life of consumable parts. The pumps are widely used for oil field and other industrial and mine enterprise-drilling well,repairing welll,transporting liquid carrier,and injecting polymer into oil layer to requirement of tertiary oil recovery.It is suit fo Rig15. The sreial products are strictly produced as per SY5138 standard of CNPC.
