RL3NB-1600 Triplex Single-Acting Back and Forth Piston Pumps

  The design characteristic of 3NB-1600 Triplex Single-Acting Back and Forth Piston Pump is the optimum parameter,appropriately increasing the stroke and displacement,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-drilling well and other industrial & mine enterprise. It is suit for Rig45-80. The serial products are strictly produced as per SY5138 standard of CNPC.
