OILWELL HD-1700-PT Mud Pump

Power End: a solid core designed for continuous operation

Transmission system: the combination of strength and precision

The drivetrain is the heart of the power end and is responsible for converting the input rotary power into strong reciprocating motion.

Crankshaft: we use one-piece forged alloy steel crankshafts made of optimized special alloy steels, such as 4340 or 35CrMo, and increase the content of elements such as nickel to significantly improve their crack propagation resistance and corrosion resistance, to ensure long-term stability under high load.

Gearing: precision-machined helical or herringbone gear system at the heart of the transmission of power.

Rack and mechanism

Strong mechanical structure is the premise to ensure the accurate alignment and long-term stable operation of the transmission system.

Frame: HD-1700-PT adopts all-welded steel power Frame, strong structure and high rigidity. This design effectively resists and absorbs the huge stress generated by the pump during operation, prevents frame deformation, and thus protects the alignment of internal high-precision components.

Bearings: we know that Bearings are the key to pump reliability. Therefore, in the power side of every key node, including pinion shaft, crankshaft, connecting rod and crosshead, we are invariably used in high-quality heavy-duty roller bearings 14. These bearings can minimize friction loss, to withstand a huge radial and axial load, is the fundamental protection of long-term trouble-free operation of the pump.

Crossheads and Guides: the Crossheads are made of high-strength ductile iron, while the Guides are made of fine abrasion-resistant bronze or superior meehanite cast iron

Lubrication system

HD-1700-PT uses a dual system of forced and splash lubrication.

Modular design and materials of excellence

The hydraulic end of the HD-1700-PT features an advanced l-shaped or Valve-Over-Valve multi-modular design. We don't compromise on material selection. All hydraulic end modules are forged from the highest quality alloy steel (AISI 4135,35CRMO or 40CrMnMo) . Forging ensures the continuity and compactness of grain flow inside the material, fundamentally eliminates the defects such as porosity and inclusions that may exist in the casting, and endows the module with unparalleled strength and toughness, it can calmly cope with the huge pressure of 7500 PSI.

Strictly adhere to the API 7K standard

All of our hydraulic ends and key load-bearing components are designed, manufactured and tested in strict accordance with API Spec 7K. API 7K is more than just an industry label. It is our solemn commitment to product security, reliability, and interchangeability. During the manufacturing process, each module is subjected to multiple non-destructive testing (NDT) , including ultrasonic testing, magnetic particle testing, and penetrant testing, to ensure the absolute purity of the material inside, any potential safety hazards are eliminated from the source. Choosing an HD-1700-PT that meets the API 7K standard means you've chosen the highest standards of safety and quality.

In drilling operations, the real cost is not only in the initial procurement, but also in the operation and maintenance throughout the life cycle. The Oilwell HD-1700-PT offers a range of high-performance, ultra-long-life perishables that help customers significantly reduce downtime and replacement frequency with the lowest total cost of use (TCO) .

System support and maintenance

In addition to the core components, the HD-1700-PT's design includes critical subsystems to support its efficient operation and extended life.

Liner Cooling System: each pump is standardly equipped with its own Liner spray Cooling System. Pulsation Dampener: the reciprocating characteristics of a triplex pump determine that there will be natural pressure fluctuations in its discharge. To this end, HD-1700-PT in the discharge manifold equipped with high-performance pulse dampener. It acts as a"Pressure sponge", absorbing the peak pressure generated by each piston action and releasing energy during the intermission, thus greatly smoothing the pressure curve in the discharge line.
