EWECO E-800 Mud Pump

Exceptional Power End Design: The Core of Lasting Durability

Power End Frame: An Unshakable Foundation

The power end frame of the EWECO E-800 is constructed from welded high-strength steel plates. This structural design provides unparalleled rigidity and strength.

Crankshaft: The Source of Smooth Power

The crankshaft component is first forged from high-quality alloy steel, then undergoes precision welding and machining to achieve perfect concentricity and inherent balance.
Gear and Bearing System: Guarantee of Efficient Power Transmission

The E-800 employs precision-machined steel herringbone gears. This tooth profile design ensures smooth transition during gear meshing, effectively transmits greater torque, while minimizing noise and vibration. Furthermore, the E-800's power end fully utilizes high-performance anti-friction roller bearings instead of traditional bushings (babbitted bearings). Roller bearings, by replacing sliding friction with rolling friction, significantly reduce energy loss and heat generation, offering a longer expected service life and higher mechanical efficiency.
Lubrication System: Comprehensive Protection, Impeccable

To ensure all critical moving components receive adequate lubrication under any operating condition, the E-800 is equipped with a dual (redundant) fail-safe internal lubrication system. This system continuously and reliably supplies clean, cooled lubricating oil to core components like gears, bearings, and crossheads, effectively carrying away heat generated by friction and preventing premature component wear.

Highly Efficient and Reliable Fluid End: Confronting High-Pressure Challenges with Ease

Fluid End Module and Design

The E-800's fluid end features a modular design, which greatly simplifies field maintenance and component replacement. Each module is manufactured from high-strength alloy steel (35CrMo or 40CrMnMo) using an integral forging process, eliminating internal defects like sand holes or cracks that can occur with casting. The forged modules undergo strict heat treatment and multiple non-destructive testing stages, ensuring they can withstand working pressures up to 5,000 PSI and possess excellent fatigue and corrosion resistance.

High-Performance Wear Parts: Extending Life, Reducing Costs

Liners: We offer liners in various materials, including industry-standard high-chrome alloy liners and top-performance zirconia ceramic liners. High-chrome liners offer excellent wear resistance, while zirconia ceramic liners represent the pinnacle of current technology. Ceramic material boasts extremely high hardness, wear resistance, corrosion resistance, and temperature resistance. Its service life can exceed 4000 hours, several times that of traditional bi-metallic liners. A smoother inner wall also significantly reduces wear on pistons, drastically lowering maintenance frequency and spare part costs.

Pistons and Valves: The E-800 can be equipped with various high-performance pistons, such as the Blue Lightning, Green Duo, and White Lightning series. These pistons are made from advanced materials like polyurethane, enabling them to adapt to different drilling fluid chemical environments and temperatures. Simultaneously, we offer various series of valves and seats like Roughneck and Supreme. Their reliable design and wear-resistant materials ensure sealing performance under high pressure and long service life.

High-Efficiency Liner Wash System: The E-800 is equipped with a high-capacity liner wash system. By continuously spraying cooling and lubricating fluid onto the piston and liner inner wall, it effectively removes the immense heat generated by reciprocating motion, preventing piston and liner overheating failure, thereby significantly extending their service life.

Metal-to-Metal Liner Locking: To ensure absolute stability of the liner under high-pressure conditions, the E-800 employs a reliable metal-to-metal locking structure. This design provides powerful locking force, effectively preventing minute movement or slippage of the liner under high-pressure impact, guaranteeing sealing integrity and the pump's continuous, efficient operation.

Why Choose the EWECO E-800? - Your Value Choice

Choosing the EWECO E-800 means you are selecting not just a pump, but a reliable solution that creates long-term value for you.

Exceptional Power-to-Weight Ratio: While delivering powerful performance up to 847 HP, the E-800 maintains a net pump weight of 22,500 lbs. This outstanding design sets a new benchmark in the industry, saving customers significant costs and time in equipment transportation, lifting, and site layout. It is particularly suitable for offshore platforms with limited space or land rigs requiring rapid mobility.

Lower Total Cost of Ownership (TCO): The core of EWECO's design philosophy is to create long-term value for customers. Through the use of more durable forged steel crankshafts, longer-life full roller bearings, a reliable dual lubrication system, and high-quality fluid end wear parts, the E-800's Mean Time Between Failures (MTBF) is significantly improved. This translates to less maintenance demand, shorter downtime, and lower spare part consumption. These factors work together to minimize your total cost of ownership over the entire lifecycle of the equipment.

Comprehensive Compatibility and Support: As an OEM manufacturer, we are committed to providing full support for every EWECO pump. We maintain a complete inventory of E-800 spare and wear parts, ensuring you have access to components that perfectly match the original equipment when needed, thus guaranteeing the pump's optimal performance and reliability. All our products are designed and manufactured in strict accordance with API 7K quality standards-our solemn commitment to quality. Additionally, we offer customization services, including color, to meet the specific needs of your project.
