W-440 Pump can be widely used in all kinds of worksin oil field. When the cylinder liner specification is 6"-3 1/2", pistonstructure is recommended and it is suitable for Oil-Well Repair andshallow-well drilling, etc. When the cylinder liner specification is 3 1/4"-2",axial piston structure is recommended and it is suitable for high-pressurework.
W-440 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.
W-440 Mud Pump Single-acting Triplex Pump can be used widely in oilfield operation. Liner size from 3-1/4"---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.
W-440 Mud Pumps are mainly used in oil field and geological prospecting for well drilling, well work-over, cementing, water shut off, water flooding and sending mud, clay, grout and so on.
