Description
Technical Overview
The fuel injection pump is the heart of the engine’s combustion system. For the MAN 21/31 series, this pump is built as a robust, single-cylinder unit capable of generating the extreme pressures required to meet international emission and efficiency standards. Sourcing a complete assembly ensures that all internal components—including the barrel & plunger, delivery valve, control rack, and roller guide—are perfectly synchronized and ready for immediate installation.
- Compatible Engine Type: MAN 21/31, 21/31H, and 21/31 Series GenSets.
- Component Type: Complete Fuel Injection Pump Assembly.
- Fuel Compatibility: Heavy Fuel Oil (HFO), Marine Diesel Oil (MDO), and Marine Gas Oil (MGO).
- Build Standard: Heavy-duty monobloc housing designed for high-fatigue mechanical and hydraulic stress.
Key Features & Performance
- Plug-and-Play Maintenance: Replacing individual internal parts on a vessel can be time-consuming and risks contamination. A complete pump assembly allows for immediate swap-out, reducing vessel downtime during critical overhauls.
- Factory-Calibrated Timing: The control rack and internal helix are factory-set to ensure uniform fuel delivery and perfect load balancing across all engine cylinders.
- High-Pressure Integrity: Engineered to maintain maximum injection pressures without internal leakage, ensuring clean ignition, reduced exhaust gas temperatures (EGT), and optimized specific fuel oil consumption (SFOC).
- Heavy Fuel Oil (HFO) Readiness: Built with advanced metallurgy and specialized clearances that handle the high temperatures and high viscosities associated with heated heavy fuel oil.
Why Source from Heybeli Marine?
Critical fuel systems require absolute reliability. Heybeli Marine ensures your vessel’s power plants remain operational with:
- Fully Tested Units: Every complete pump assembly undergoes rigorous pressure and flow bench testing to guarantee it meets or exceeds original manufacturer specifications.
- Rapid Global Supply: We maintain stock of complete MAN 21/31 pumps in strategic logistics hubs, enabling fast delivery to ports and shipyards worldwide.
- Comprehensive Spares Support: We don’t just supply the pump; we also provide the associated high-pressure injection pipes, sealing kits, and mounting gaskets required for a complete job.
- Expert Technical Verification: Our technical team cross-references your engine serial number and pump nameplate data to guarantee 100% compatibility before dispatch.
Technical Installation Note: When installing a complete new fuel injection pump, it is crucial to inspect the engine’s camshaft lobe and roller guide for wear. Additionally, ensure the fuel rack linkage moves freely to prevent any over-speed or sticking issues during initial startup.
