Bomco F800 Mud Pump Discharge Manifold

Product Introduction

We supply a complete, OE-compatible Bomco F800 mud pump discharge manifold, including all core components listed—from the discharge four Teeto the strainer , JA-3 safety valve, pressure gauge, gaskets, fasteners, and air bladder . Every part is precision-manufactured to match the original equipment specifications exactly, ensuring seamless integration with the Bomco F800 mud pump without modifications. The main manifold body and discharge four Tee are crafted from American A487-9D cast iron and 35CrMo high-quality casting blanks, processed through modulation treatment to achieve a hardness of HB 195-235, delivering excellent corrosion resistance, wide temperature adaptability, and high strength. All components undergo strict quality control, including hydrostatic pressure testing , non-destructive testing (NDT), and dimensional verification, ensuring compliance with API 7K standards and reliability in harsh drilling environments.

Function Instructions

The Bomco F800 discharge manifold performs four essential functions that are critical to the mud pump’s operation, directly solving industry pain points and ensuring safe, efficient drilling fluid transfer:

• High-Pressure Fluid Distribution: The discharge four Tee  and inout connectorchannel high-pressure drilling fluid from the pump to the downstream jumper hose and standpipe manifold[1][7], ensuring consistent flow to the wellbore—vital for maintaining drilling efficiency and formation pressure balance[5].
• Contamination Filtration: The strainerand strainer coverfilter out debris, sand, and solid particles from the drilling fluid, preventing clogging and damage to downstream componentshat can lead to costly repairs and downtime[3].
• Pressure Monitoring & Overpressure Protection: The pressure gauge  and pressure gauge seat  provide real-time pressure readings, allowing technicians to monitor system performance and detect abnormalities. The JA-3 safety valve automatically release excess pressure if it exceeds the safe limit, protecting the manifold, pump, and downstream equipment from catastrophic damage

Structural Characteristics

The Bomco F800 discharge manifold features a robust, precision-engineered structure that prioritizes high-pressure resistance, corrosion resistance, and easy maintenance—aligned with the Bomco F800 mud pump’s fluid end design. Key structural features include:

• Manifold Core: The discharge four Tee (AH100101200300) and main body are made of American A487-9D cast iron and 35CrMo forged alloy steel[3][4], processed through modulation treatment to achieve a hardness of HB 195-235, ensuring they can withstand the Bomco F800’s rated pressure of 35 MPa and test pressure of 52 MPa without deformation or leakage[3]. The manifold’s internal channels are precision-machined to minimize flow resistance, ensuring efficient fluid transfer.
• Filtration & Safety System: The strainer (AH100101190200) is designed with a fine mesh to capture particles larger than 0.5 mm, while the strainer cover (AH100101190201) allows for easy removal and cleaning. The JA-3 safety valve (AH0000060100) is calibrated to trigger at 38 MPa (10% above the rated pressure), providing reliable overpressure protection, and the air bladder (AK45350100, KB-45) helps stabilize pressure and reduce fluid pulsation[3].
• Sealing & Fastening Components: O-rings (165×7, GB3452.1-82) and gaskets (T508-5003, T508-5002 R44) are made of high-temperature, high-pressure resistant rubber, capable of withstanding temperatures from -20°C to 120°C and pressures up to 40 MPa. High-strength studs (M27X170, T503-1004) and nuts (M27, T507-2005) ensure secure assembly, while LETA Glue 243 prevents fastener loosening and enhances sealing performance.

Applicable Working Conditions

The Bomco F800 discharge manifold is engineered to withstand the harsh, high-pressure 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 manifold operates under continuous high pressure (up to 35 MPa) and handles high-density drilling fluids[5][7].
• Extreme environmental conditions, including high humidity (up to 95%), low temperatures (-20°C to 60°C), and dusty/sandy work sites. The A487-9D cast iron and 35CrMo material provide excellent corrosion and rust resistance[3][4], ensuring the manifold remains reliable in harsh environments.
• High-stress drilling environments, such as heavy-duty drilling with abrasive drilling fluids (containing sand and debris), where the strainer (AH100101190200) prevents clogging and the robust manifold body resists wear and damage. The manifold can operate continuously for 8,000+ hours without major maintenance[3].
• Continuous operation scenarios (24/7 drilling), where reliability is critical to meeting drilling deadlines. The manifold’s low maintenance requirements, leak-proof design, and overpressure protection minimize downtime and ensure uninterrupted drilling fluid transfer[5].

On-Site Fault Repair Cases

Below are three real-world on-site repair cases, demonstrating how our OE-compatible parts and manifold solve common Bomco F800 discharge manifold issues quickly, minimizing downtime and preventing further damage:

Case 1: Fluid Leakage. A field team noticed high-pressure fluid leakage at the flange (T508-1002) connection, leading to reduced system pressure and safety risks. Inspection revealed worn gaskets (T508-5002 R44) and improper sealing. Solution: Replace the gaskets with our OE-compatible parts, apply LETA Glue 243 (17050601010024300) to the flange surface, and torque the M27X170 studs (T503-1004) to 280 N·m. Leakage stopped immediately, and system pressure was fully restored within 45 minutes[2].

Case 2: Pressure Fluctuations & Clogging. The pressure gauge (YK-150, 380207192402511000) showed erratic readings, and pump efficiency dropped by 20%. Inspection found the strainer (AH100101190200) was clogged with debris, restricting fluid flow. Solution: Remove the strainer cover (AH100101190201), clean the strainer, replace the O-ring (530301011650070000) with our OE part, and reassemble. Pressure fluctuations eliminated, and pump efficiency returned to normal within 1 hour[2].

Case 3: Safety Valve Failure. The JA-3 safety valve (AH0000060100) failed to trigger during overpressure (system pressure reached 40 MPa), risking manifold damage. Inspection revealed a faulty safety valve and worn safety valve take over (AH100101200200). Solution: Replace the safety valve and take over with our OE-compatible parts, calibrate the safety valve to trigger at 38 MPa, and test the system. The safety valve functioned properly, and the manifold was back in operation within 2 hours, preventing catastrophic damage[3].

Maintenance Recommendations

To maximize the service life of the Bomco F800 discharge manifold (target service life: 9,000+ hours) and ensure reliable performance, follow these practical guidelines aligned with API 7K recommended practices and industry best practices[3][5]:

• Daily Inspection: Check for fluid leakage at flange connections, gaskets, and O-rings. Monitor the pressure gauge (YK-150) for abnormal fluctuations[2], and ensure the safety valve (AH0000060100) is free of debris and functioning properly. Inspect the strainer cover for signs of loosening.
• Regular Maintenance: Every 1,500 hours of operation, clean the strainer (AH100101190200) to remove accumulated debris. Replace the O-rings (530301011650070000) and gaskets (T508-5003, T508-5002 R44) every 4,000 hours. Calibrate the pressure gauge and safety valve every 6,000 hours to ensure accurate readings and reliable overpressure protection[3].
• Lubrication & Sealing: Apply LETA Glue 243 to all gasket and flange connections during reassembly to enhance sealing performance. Ensure the air bladder (AK45350100, KB-45) is properly inflated to maintain pressure stability.
• Part Replacement: When replacing components, always use OE-compatible parts (matching the listed part numbers) to ensure compatibility and high-pressure resistance. Avoid generic parts, as they may use inferior materials (non-A487-9D cast iron[3]) or imprecise machining, leading to leakage, pressure loss, and safety hazards[6].
