Mud Pump Parts

Dezhou Rundong Petroleum Machinery Co., Ltd. provides mud pump parts for mud pump with model listed below. In addition, we can manufacture those parts according to customers’ design drawings.
    1. Fluid End Module
    2. Fluid End Module As an important component on the fluid end of mud pump, our Rundong value module is made premium 8620 or 4135 alloy steel with forging, normalizing, rough machining and then quenching and tempering processes. In this way, the interior of the fluid end module will have hardness in the range of HB285 to HB330.
    1. Pump Liner
    2. Pump Liner Rundong’s mono-metal liner has its inner bore quenched with the carburized layer thickness as 1.5 to 1.8mm to achieve hardness of 58 to 60 HRC. The liner features high hardness, great corrosion resistance, no deformation and high surface finish.
    1. Piston Assembly
    2. Piston Assembly Piston is one of the wear parts consumed the most in mud pump for drilling system. Rundong manufactures pistons of various specifications, which can be applied on different drilling pumps, such as F series, 3NB series, P series, PZ series and UNB series.
    1. Piston Rod
    2. Piston Rod Our company provides piston rods and extension rods for different mud pumps including F series, 3NB series, QZ series, PZ series, P series, etc.
    1. Valve Assembly
    2. Valve Assembly Rundong’s valve body and valve seat are made of premium alloy steel though one-piece forging and carburizing treatment processes, thereby ensuring high intensity. In addition, precise calculation is performed and CNC machining is conducted for the dimensional matching of valve seat and valve body working...
    1. Pulsation Dampener
    2. Pulsation Dampener Rundong provides discharge pulsation dampener assembly, discharge pulsation dampener capsule and suction pulsation dampener capsule and related accessories, which all could be applied on different types of mud pumps such as F series, PZ series and P series, etc.
    1. Safety Valve
    2. Safety Valve Our shear safety valve is able to ensure normal operation of the mud pump in conditions with working pressure less than rated value. It comes in flange type and thread type. It features great flexibility in toggling on and off, small pressure-bearing area of the piston attached, easy resetting, good compatibility with most types of mud pumps.
    1. Flanges and Cylinder Parts
    2. Flanges and Cylinder Parts Rundong provides different flanges and cylinder parts, which include cylinder head, cylinder liner, valve cover, cylinder head flange and cylinder liner flange, etc. Those parts could be applied on various mud pumps, such as F series, 3NB series, PZ series and P series.
    1. Rubber Pump Parts
    2. Rubber Pump Parts Rundong provides varieties of rubber pump parts including piston rubber cup, valve rubber, seal ring, O-ring, gasket, etc. These rubber parts could be applied on different mud pumps, such as F series, 3NB series, PZ series and P series.
    1. Crosshead and Parts
    2. Crosshead and Parts Rundong manufactures crossheads, crosshead pins and crosshead slides for different mud pumps including F series, 3NB series, PZ series and P series. Our crosshead pins are made of premium structural alloy steel through one-piece forging process, while crossheads and crosshead slides are made...
    1. Crankshaft
    2. Crankshaft Rundong crankshaft is made of 4340 alloy steel with high content of nickel through forging process, significantly preventing the generation and propagation of cracks. Thanks to abundance of nickel, the crankshaft also features high corrosion resistance. Furthermore, static balance will be achieved...
    1. Pinion Shaft
    2. Pinion Shaft Rundong pinion shaft is made of 4340 alloy steel though forging process. With great precision, the double helical gear machined on the shaft will ensure smooth power transmission along the whole tooth width and reduce gear gap significantly. As a result, hammering caused by change of speed will be efficiently eliminated.
    1. Other Mud Pump Parts
    2. Other Mud Pump Parts Rundong offers drilling rig mud pumps and pump components. There are wide ranges of mud pump parts like bearings, manifolds, cross fittings, pump housings, clamps and others.

The mud pump parts we provide include fluid end module, pump liner, piston, valve assembly, piston rod, extension rod, pulsation dampener, safety valve, flange and cylinder, rubber part, crosshead, crosshead pin, crosshead slides, crankshaft assembly, pinion shaft, etc.
