    II. Tructure Character :
        The pump is compact structure, small volume, lightweight, integrated herringbone gear pair, large transmit torque and smooth run. Crankshaft is welding forged and light weight without libration
        LW440 Mud Pump Single-acting Triplex Pump can be used widely in oilfield operation. Liner size from 31/4"-4 1/2" is better-adopted piston structure for workover operation and
    low well drilling operation while plunger structure for liner size from 2---31/4" for high- pressure operation.
