Product Introduction
We supply a complete, OE-compatible Bomco F800 power end lubrication assembly, including all 58 core components listed—from the 2S oil gear pump and oil gear pump assemblyto copper pipes, connectors, manifolds, filters, and fasteners. Every part is precision-manufactured to match the original equipment specifications exactly, ensuring seamless integration with the Bomco F800 mud pump without modifications. The assembly features a forced lubrication design, where the 2S oil gear pump draws clean oil from the reservoir, pushes it through the oil filter assembly to remove impurities, and distributes it via manifolds and copper pipes to critical power end components through oil jets. All parts undergo strict quality control, including pressure testing and material verification, to meet API 7K standards and ensure durability in harsh drilling conditions
Function Instructions
The Bomco F800 power end lubrication assembly performs three essential functions that directly address industry pain points, ensuring the mud pump’s power end operates reliably and efficiently:
- Continuous Lubrication Delivery: The 2S oil gear pump delivers a steady flow of lubricating oil (up to 8 L/min) to key power end components, forming a protective oil film that reduces friction between moving parts by 60% and prevents metal-to-metal contact—one of the leading causes of power end failure. This ensures the power end operates smoothly even under continuous high-load conditions.
- Oil Filtration & Purification: The oil filter assembly removes impurities from the lubricating oil, preventing clogging of oil jets and damage to bearings and gears. Clean oil extends the service life of lubricated components by 40% and reduces maintenance frequency.
Structural Characteristics
The Bomco F800 power end lubrication assembly features a robust, modular design that prioritizes durability, easy maintenance, and reliable performance—aligned with the Bomco F800 mud pump’s power end structure. Key structural features include:
- Core Pump Units: The 2S oil gear pump and oil gear pump assemblyare constructed with high-strength cast iron bodies and precision-machined gears, capable of withstanding pressures up to 1.6 MPa and temperatures ranging from -20°C to 120°C. The gear pump operates with low noise, ensuring consistent oil delivery.
- Oil Distribution System: Copper pipesand connectors are precision-machined for leak-proof connections, with pipe clamps providing stable mounting to reduce vibration by 30% during operation. Manifolds distribute oil evenly to multiple oil jets, ensuring all critical components receive adequate lubrication.
- Filtration & Safety Components: The oil filter assemblyfeatures a replaceable filter element for easy maintenance, while the safety relief valve automatically releases excess pressure to protect the system. Gaskets and seal gaskets ensure leak-proof performance, with Loctite 609 used to secure threaded connections and prevent loosening.
- Accessibility & Maintainability: The assembly’s modular design allows for easy access to key componentswithout disassembling the entire system. Pipe elbows and connectors are positioned to fit the Bomco F800’s power end layout, simplifying installation and maintenance.
Applicable Working Conditions
The Bomco F800 power end lubrication assembly is engineered to withstand the harsh, variable conditions of oil and gas drilling, making it suitable for all scenarios where the Bomco F800 mud pump is deployed:
- Onshore and offshore drilling operations, including deepwell, horizontal, and geothermal drilling, where the power end operates under continuous high load and pressure.
- Extreme environmental conditions, including high humidity (up to 95%), low temperatures (-20°C to 60°C), and dusty/sandy work sites. The assembly’s components are treated with anti-corrosion coatings, and copper pipes are resistant to rust and abrasion.
- Aggressive drilling environments, where the lubricating oil may be exposed to contaminants (e.g., mud, dust). The oil filter assembly ensures clean oil delivery, preventing component damage.

On-Site Fault Repair Cases
Below are three real-world on-site repair cases, demonstrating how our OE-compatible parts and assembly solve common Bomco F800 power end lubrication issues quickly, minimizing downtime:
Case 1: Low Lubrication Pressure. A field team noticed the pressure gaugeshowing pressure below 0.3 MPa, with abnormal noise from the power end. Inspection revealed a clogged oil filter assembly and dirty oil. Solution: Replace the oil filter assembly with our OE-compatible part, drain and replace the lubricating oil, and clean the copper pipes . Pressure returned to 0.7 MPa within 45 minutes, eliminating the noise and preventing bearing damage.
Case 2: Oil Leakage at Connections. Leakage was detected at the pipe connector A10, causing reduced oil flow and pressure. The issue was a worn gasket combination and loose threads. Solution: Replace the gasket combination, apply Loctite 609 to the threads, and tighten the connector to the recommended torque. Leakage stopped immediately, restoring full lubrication performance.
Case 3: Oil Gear Pump Failure. The 2S oil gear pumpfailed to deliver oil, leading to overheating of the power end. Inspection revealed a damaged gear inside the pump and a worn key . Solution: Replace the 2S oil gear pump and key with our OE-compatible parts, prime the pump with clean oil, and restart the system. The pump resumed normal operation within 1 hour, reducing bearing temperature to 65°C and preventing further damage.
Maintenance Recommendations
To maximize the service life of the Bomco F800 power end lubrication assembly and ensure consistent performance, follow these practical guidelines aligned with API 7K recommended practices and industry best practices:
- Daily Inspection: Check the pressure gauge to ensure system pressure is between 0.3-1.0 MPa. Inspect all pipe connections and gaskets for leaks, and check the oil level to prevent the oil pump from running dry. Listen for abnormal noise from the oil pump and check for excessive vibration[1].
- Regular Maintenance: Every 1,500 hours of operation, replace the oil filter assembly and lubricating oil . Clean the copper pipes and oil jets to remove debris buildup, and inspect the safety relief valve (YYFJ-L20) for proper operation.
- Seasonal Care: In cold environments, use a low-temperature lubricating oil to prevent oil thickening. In hot environments, check the oil temperature regularly and clean the oil cooler if needed to maintain proper heat dissipation.
- Part Replacement: When replacing components, always use OE-compatible parts o ensure compatibility. Avoid generic parts, as they may have incorrect dimensions or inferior materials that lead to leaks, pump failure, or inadequate lubrication.
