Fuel Injection Service Partner for Shipyards & Marine Engine Rebuilders

Specialist Workshop Support in the Background - Your Company Remains the Service Partner to Your Customer

Shipyards and engine rebuilders often have the mechanical capability to remove, rebuild and recommission a marine engine but do not maintain dedicated test equipment for every historical fuel-injection system. Einspritzpumpen Manufaktur NRW supports such companies as a specialist workshop for the injection equipment itself.

Our marine service is not limited to one pump manufacturer or one engine family. Depending on pump design, condition, technical documentation, spare-parts availability and suitable test-bench adaptation, we assess, overhaul, repair and calibrate mechanical fuel injection pumps from Bosch, LÓrange (also searched as L'Orange), Kugelfischer and other manufacturers. We accept enquiries for mechanical fuel-injection equipment used on all categories of marine engines operating either at fixed speed or across a variable speed range, including main propulsion, auxiliary, generator and other shipboard duties. Common Rail systems are not part of this service scope.

Bosch, LÓrange, Kugelfischer and Mixed-Fleet Support

Our B2B marine work is not restricted to one brand. We assess mechanical Bosch, LÓrange, Kugelfischer and other injection-pump designs used across different engine makes and generations. This is useful for shipyards and rebuilders that service mixed fleets or vessels where the original engine manufacturer no longer provides complete fuel-injection support.

Fixed-Speed and Variable-Speed Engines

We support both variable-speed propulsion engines and fixed-speed auxiliary or generator engines. When you send a pump, please state the engine duty and rated operating data. The required calibration points for a propulsion engine may differ from those of a generating set that must operate consistently at one defined speed.

Planned Engine Overhauls

For planned rebuilds, the most efficient approach is to identify the pump before engine dismantling begins. This gives time to verify test data, locate parts and decide whether the full injector set should be processed together with the pump. For older engines, early identification can be the difference between a controlled overhaul and a late spare-parts problem.

Unexpected Failures and Difficult Components

When a shipyard encounters an injection pump that is seized, corroded, incomplete or previously modified, photographs and identification data should be sent before further dismantling. The original condition can provide useful evidence about wear, leakage, corrosion and prior interventions.

Large and 16-Cylinder Injection Systems

For large inline pumps and mechanically coupled V-engine pump systems, we can evaluate test arrangements that ordinary automotive diesel benches cannot accommodate. Our dedicated large-pump equipment includes volumetric measurement using graduated glass cylinders and supports comparative testing across complete multi-cylinder systems where the pump configuration is suitable.

Documentation and Communication

B2B projects can be handled using your project reference, purchase order or vessel reference. Technical findings, component questions and approval points can be communicated directly with the responsible workshop, superintendent or purchasing contact nominated by your company.
