Built for durability and corrosion resistance, this pump handles high flow rates and harsh marine environments. Its efficient performance ensures stable engine temperatures, contributing significantly to the reliability and longevity of the engine under continuous load.

The indicator valve, identified by code H 27750, is an essential diagnostic component used in the ASL25 diesel engine to monitor cylinder pressure during operation. By allowing temporary connection to pressure gauges, it provides critical insight into combustion performance and engine health. Built to endure high pressure and thermal cycles, the valve ensures safe and reliable readings. This makes it an invaluable tool for maintenance teams aiming to optimize performance, detect issues early, and extend engine life.

The oil scraper marked as H 34028 plays a vital role in controlling oil distribution within the ASL25 engine. This component ensures that excess lubricating oil is removed from the cylinder walls during piston movement, preventing oil buildup and minimizing consumption. Its precision design helps maintain optimal lubrication, reduces emissions, and protects engine parts from unnecessary wear. Regular inspection and replacement of the oil scraper are essential to maintaining engine efficiency and complying with environmental standards.

The spring with code number H 43627 is a resilient mechanical component designed for critical use within the ASL25 diesel engine system. Its primary function is to store and release mechanical energy, either to maintain pressure, absorb shock, or ensure proper positioning of connected elements. Built from high-quality, fatigue-resistant material, this spring withstands demanding operational conditions typical of marine and industrial environments. Whether part of a valve mechanism or a tensioning system, its reliability directly affects engine performance and longevity.

Designed specifically to support flexible rod K 72135, the spring guide with code K 72137 ensures proper alignment and controlled movement of the rod within the mechanical system of the Sulzer ZV40/48 engine. This component helps maintain tension and reduces the risk of unwanted deflection or vibration, especially under dynamic operating conditions. Made from durable materials and engineered for high precision, the spring guide extends the lifespan of connected parts and contributes to smoother overall engine performance.

The locking screw with code K 73034 is a seemingly small but essential fastening element designed for securing the casing of the cooling water pump in the Sulzer ZV40/48 engine. Its primary function is to hold the casing parts in position under pressure, vibration, and thermal expansion, preventing any misalignment or leakage. Precision-engineered and built to withstand mechanical stress, this screw contributes directly to the durability and stability of the entire cooling system. Regular inspection and correct torque application are key to ensuring its effectiveness.
