Description
Technical Overview
The Yanmar M220 engine is a robust power plant that operates under substantial thermal and mechanical loads. Sourcing a complete fuel injection pump assembly ensures that all critical internal components—including the high-pressure barrel & plunger element, delivery valve, control rack, and return springs—are pre-assembled and perfectly synchronized inside a high-strength monobloc housing. This eliminates the risk of onboard assembly errors and ensures immediate operational readiness.
- Compatible Engine Type: Yanmar M220, M220L, M220AL, and M220-Series engines (Propulsion & GenSet configurations).
- Component Type: Complete Fuel Injection Pump Assembly.
- Fuel Compatibility: Heavy Fuel Oil (HFO), Marine Diesel Oil (MDO), and Marine Gas Oil (MGO).
- Housing Construction: High-grade, forged cast iron housing designed to withstand extreme pressure pulses and prevent body cavitation.
Key Features & Performance
- Rapid Plug-and-Play Installation: Drastically reduces critical downtime. Instead of performing time-consuming, sensitive overhauls of internal pump components in a challenging engine room environment, the ship’s crew can rapidly swap the entire assembly.
- Precision Metering & Timing: The control rack and internal plunger helix are factory-set to guarantee identical fuel delivery across all cylinders. This ensures uniform thermal loading, balanced cylinder exhaust temperatures, and stable engine governing.
- Optimized High-Pressure Output: Engineered to hold extreme injection pressures without internal pressure drop or back-leakage, resulting in clean fuel atomization, reduced soot formation, and low Specific Fuel Oil Consumption (SFOC).
- HFO Thermal-Shock Readiness: Built with advanced metallurgy and specialized clearances capable of handling the high-temperature transitions required when switching from cold Marine Gas Oil to heated, high-viscosity Heavy Fuel Oil.
Why Source from Heybeli Marine?
Critical engine components demand uncompromised quality control. Heybeli Marine supports your technical management teams with:
- Rigorous Bench Testing: Every complete Yanmar M220 pump assembly undergoes strict volumetric, pressure, and sealing tests on a calibrated fuel pump test bench before dispatch.
- Global Strategic Logistics: We maintain stock of large-bore Yanmar components to ensure immediate dispatch to major ports, dry docks, and shipyards worldwide.
- Comprehensive Spares Kit: We provide the necessary O-rings, mounting gaskets, and high-pressure line washers with the pump to facilitate a seamless replacement.
- Technical Accuracy: Our marine engineering experts cross-reference your specific pump nameplate data and engine serial numbers to ensure a 100% correct match.
Technical Installation Note: When replacing a complete fuel injection pump on the Yanmar M220 series, it is highly recommended to inspect the fuel pump roller guide and the respective camshaft lobe for pitting or abnormal wear. Always ensure that the fuel rack linkage moves smoothly with zero binding before starting the engine to prevent over-speed risks.
