The oil pump in the MAN L21/31 engine plays a vital role in circulating lubricating oil throughout the engine, ensuring all moving parts receive adequate lubrication to minimize wear and prevent overheating. Built to withstand high pressure and continuous operation, the oil pump (code H27154) is essential for maintaining engine health, reducing friction, and prolonging the engine’s lifespan.
The pump impeller with drive shaft, bearing code number K 74123, forms the dynamic heart of the Sulzer ZV40/48's fuel transfer pump. The impeller is tasked with propelling the fuel, while the drive shaft transmits power from the motor to the rotating assembly. Together, they generate the pressure and flow necessary for efficient fuel distribution. Constructed from robust, wear-resistant materials, these components are engineered for high efficiency, minimal vibration, and extended service life, playing a vital role in the consistent performance of the fuel system.
The complete fuel transfer pump, marked with code K 74100, is a central component in the Sulzer ZV40/48 engine's fuel delivery system. It is responsible for ensuring the continuous, regulated flow of fuel from storage tanks to the injection system under precise pressure. Engineered for durability and performance, this pump supports reliable engine operation even under demanding marine and industrial conditions. Its integrated design includes essential components such as impellers, shafts, and seals, all optimized for long-term service and minimal maintenance.
The packing ring identified by code number K 74130 is a critical sealing element in the Sulzer ZV40/48 diesel engine's fuel transfer pump. Designed to prevent fuel leakage under pressure, it ensures the secure containment of fuel within the pump assembly. Crafted from durable, fuel-resistant materials, the packing ring withstands high operational temperatures and mechanical stress. This small but essential component plays a vital role in maintaining fuel system efficiency and protecting surrounding engine parts from contamination and wear due to leaks.
Fuel filters in the MAN L21/31 engine are crucial for maintaining clean fuel delivery by removing contaminants such as particles and water. These filters protect the fuel injection system from clogging and wear, helping optimize combustion efficiency and extend engine life. Regular inspection and timely replacement of fuel filters (code H87511) are essential to prevent costly repairs and ensure steady engine performance.
The crankshaft is the primary component in the MAN L21/31 engine that converts the pistons’ reciprocating motion into rotational motion to drive the engine. Built from high-strength forged steel, it must withstand significant mechanical stresses and torque while maintaining precise alignment. Its robust design and durability (code E265280000) are critical to the engine’s overall reliability and long-term performance.
