Introduction
This document focuses on supplying high-quality, compatible components specifically designed for BPM-DQ70BSC top drives, TDS systems, and their supporting hydraulic power units (HPU). Our product range covers over 60 core components, including explosion-proof valves, sensors, hydraulic cylinders, seals, hoses, and mechanical parts, with key part numbers such as 9703340000 (Upper IBOP), 5126000560 (Explosion-Proof Magnetic Valve), 4807101010 (25L Rubber Bladder), and 5126000441 (Lubricating Oil Pump). We mainly serve oilfield drilling companies, on-site maintenance teams, and equipment repair workshops—our core goal is to solve the most painful problems in oilfield operations: unplanned downtime caused by component failure, high maintenance costs from mismatched parts, and safety hazards from low-quality replacements. All components are manufactured in strict compliance with API 6A, API 7K, and ATEX standards, and are fully compatible with BPM-DQ70BSC top drives and TDS systems, including those matched with National Oilwell Varco Blak-Jak Washpipe Cartridge systems (P/N 80506100). Backed by professional manufacturing experience, each batch of products undergoes 100% factory inspection, with exclusive test data to ensure reliability, helping customers minimize downtime and reduce maintenance costs.
Product Overview
Core Product Categories & Functional Descriptions
Our components are categorized by their functional roles in BPM-DQ70BSC top drives and TDS systems, each engineered to address specific on-site pain points:
• Explosion-Proof Electrical & Instrument Components: Including MB330.0-40MPA explosion-proof pressure transformer (P/N 3808000120) and GW200A oil temperature sensor (P/N 3808000072), which provide accurate pressure and temperature data in flammable and explosive oilfield environments, avoiding safety accidents caused by inaccurate monitoring. The explosion-proof magnetic valve (P/N 5126000560) meets ATEX certification, ensuring stable operation under 24V DC power supply without leakage or misoperation.
• Hydraulic Components: TDS-specific valves (P/N 5126000500, 5126040100) control oil flow and pressure, solving the problem of unstable hydraulic system operation; counterbalance cylinders (P/N 9705221100) and link tilt cylinders (P/N 9705227200) bear loads up to 3500kN, with a service life of 8,500 working hours, 2,500 hours longer than ordinary alternatives. The 1.5KW hydraulic cooling fan motor (P/N 3101030320) maintains system temperature, preventing overheating failures.
• Seals & Sealing Components: BPM-DQ70BSC-specific O-rings (P/N 5303001830, 5303001820) and sealing beads (P/N 5304010040) are made of high-temperature and oil-resistant fluororubber, withstanding temperatures up to 130℃ and pressure up to 45MPa, eliminating oil leakage—a common fault in hydraulic systems.
• Mechanical & Structural Components: The 40CrMnMoA spindle (P/N 9701000001) and brake disc (P/N 9702012003) are made of high-strength alloy steel, with tensile strength ≥ 850MPa, avoiding breakage during high-load drilling. Upper and lower IBOP (P/N 9703340000, 9703320000) ensure safe well control, preventing wellbore overflow.
• Filters & Auxiliary Tools: Strainers (P/N 5126000980) and filter elements (P/N 5126070070) filter impurities as small as 8μm, reducing wear on hydraulic components; nitrogen filling tools (P/N FPU-1-250F250F25G11A3K) and pocket pressure measures (P/N SMB20-2-250/400BAR) facilitate on-site maintenance, saving repair time.
Structural Features
All components adopt a modular and precision-machined design, making installation and disassembly quick and easy—reducing on-site maintenance time by 35 minutes per component on average. Key structural advantages include: precision-machined sealing surfaces (surface roughness ≤ 0.6μm) to ensure tight sealing; corrosion-resistant coating on external components to resist salt spray and humidity in offshore and desert oilfields; and reinforced load-bearing structures for mechanical parts, such as the brake hub (P/N 9702012004) made of 42CrMo steel, which can withstand 1120N·m torque without deformation. Additionally, all electrical components use flame-retardant materials, complying with EX d IIB T6 explosion-proof standards, ensuring safety in flammable environments.
Applicable Working Conditions
Our components are fully adapted to the harsh working conditions of oilfield operations, including onshore desert oilfields, offshore platforms, and high-temperature, high-pressure (HTHP) wells. They can operate stably in temperature ranges from -45℃ to 130℃, pressure up to 45MPa, and humidity up to 98%. Whether it’s the extreme temperature differences of desert oilfields or the high salt spray of offshore platforms, our components maintain reliable performance, ensuring continuous operation of BPM-DQ70BSC top drives and TDS systems. They are also compatible with National Oilwell Varco Blak-Jak Washpipe Cartridge systems, meeting the needs of mixed-equipment operations.

Customer feedback: "The sensor provides accurate data, and the filter effectively purifies oil, ensuring stable gearbox operation."
Maintenance & Operation Tips
Our engineers summarize practical on-site maintenance tips to extend component service life and reduce failures, based on years of oilfield experience:
• Hydraulic valves & cylinders: Check oil cleanliness every 450 working hours; replace hydraulic oil every 1400 working hours. Do not use unqualified oil, as it will wear valve cores and cylinder walls—our engineers remind that using matching oil can extend component life by 3,000 hours.
• Seals: Inspect for aging or deformation every 280 working hours; replace seals if they become hard or cracked. Apply special lubricant before installation to avoid damage during assembly—this simple step reduces seal failure by 60%.
• Explosion-proof components: Keep connectors clean and dry; check cable connections every 380 working hours. Do not use non-explosion-proof tools near these components, as it may trigger safety hazards. Regularly check explosion-proof shells for damage.
• Mechanical parts: Apply grease to spindles, bearings, and rollers every 180 working hours; check for loose fasteners. For IBOP, test closing performance every 10 days to ensure it can work normally in emergencies.
