Features of RL3NB Series Triplex Mud Pump:

Optimum of parameter, increased the stroke lenth and displacements appropriately, lowered the stroke reasonably, thus improved the service life of expendable parts.This series mud pumps are widely used in oilfields and other industrial mining enterprises for well drilling and well repairing etc.

This series mud pumps are strictly manufactured according to SY5138 standard of CNPC and are tested accordingly when leave factory.
