3NB Series Mud Pumps are inclusive of RL3NB-350, 3NB-500,L3NB-600, 3NB-800, 3NB-1000,L3NB-1300, 3NB-1600, 3NB-2200.
Design Features:
This series pumps optimize the parameters, increase proper stroke, increase displacement, reasonably reduce the stroke rate of improving pump suction performance and extend the service life of the vulnerable parts. This series of pumps are widely used in oil fields and other industrial and mining enterprises, drilling and workover operation etc., manufactured and carried out delivery test strictly in accordance with SY5138 standards of Ministry of Petroleum Industry.
