Brief Introduction
Mud Pump is used to circulate
drilling fluid while drilling, it is the heart part of drilling fluid
circulation system, and it is composed of Power End and Fluid End.
The products conform to API Spec 7k, and acquired the authorization to use Official API Monogram. |

Technical Performances and Structure Features
1.Power End: the frame is welding
structure with steel plate, it has high strength, rigidity and light
weight, It is stress-relieved after welding.. The transmission gears are
integral involute herringbone, with smooth running, high efficiency and
long service
life. The crankshaft is hollow one-piece casting. At the Power End, we adopt splash and forced lubrication.
2.Fluid End: compact structure is due to adopting straight pass through
fluid cylinder. The suction and discharge flange conform to ANSI and API
Spec.
3.Piston Rods and Intermediate Rods are jointed by collar couplers that allow quick installation/disassembly.
4.The piston and line bore are cooled and lubricated by independent spray pump system, has long service life.
5.The expendables are universal. |

Series F mud pump features
- Series F
mud pump has long stroke length so that stroke numbers are reduces and
fluid end quick-wear parts last longer.
- Forced
combined with splash lubrication ensure more efficient lubrication.
- Series F
pump is proper-structured, compact, durable, running smoothly and
accommodate special requirements during drilling wells ranging from
intermediate to deep depth. Series F mud pump is compact and
reliable. Suction valve and discharge valve are
interchangeable. Triple cylinders and fluid end main components on
each pump are interchangeable.
- Series F
mud pump durable fluid end greatly improves performance of triplex pump
and its unique design enables quick check and convenient repair.

W440/W446 Mud Pump Features
W440/446 Pump can be widely used in all kinds of works
in oil field. When the cylinder liner specification is 6"-3 1/2",
piston structure is recommended and it is suitable for Oil-Well Repair and
shallow-well drilling, etc. When the cylinder liner specification is 3
1/4"-2", axial piston structure is recommended and it is suitable for
high-pressure work. Specification W440 Mud Pump

Series 3NB mud pump features
- Power end:
the frame is a welded structure with steel plate, subject to post welding
internal stress relief. Gear is involute type, smooth running, high
efficiency and long service life. Crankshaft is one-piece hollow
cast. Power end is splash lubricated.
- Fluid end:
suction and discharge flange conform to ASA and API specification.
- Piston rod
and extension rod are connected with coupling for quick assembly and
disassembly.
- Bench at
the bottom of valve positioning hole prevents valve seat sinking.
Piston and liner are cooled and lubricated by separate spraying pump
device for longer service life.
- Quick-wear
parts are interchangeable.
