The assembly spray nozzles, code 200100, consist of a precisely engineered group of spray nozzles designed to deliver lubricants, cooling media, or cleaning fluids to designated areas within the MAN L21/31 engine. Working together as an integrated assembly, these nozzles ensure uniform fluid distribution, accurate atomization, and efficient coverage of critical engine components operating under high thermal and mechanical loads. Manufactured to strict dimensional and flow-performance specifications, the assembly provides reliable operation under varying pressures and temperatures while resisting wear and corrosion. Proper performance of the spray nozzle assembly contributes to improved cooling efficiency, enhanced lubrication, reduced component wear, and increased operational reliability of the engine.

The cover with splash tube, code 300100, is a multifunctional assembly within the MAN L21/31 engine that combines protective enclosure with controlled lubrication management. Designed to protect internal engine components from contamination while directing lubricating oil through the integrated splash tube, it ensures efficient lubrication and cooling of critical moving parts during engine operation. Precision-manufactured for accurate fitment and dependable sealing, the assembly is produced from durable, corrosion-resistant materials capable of withstanding continuous thermal and mechanical stresses. By optimizing oil distribution and minimizing uncontrolled oil splash, the cover with splash tube helps reduce component wear, improve operational reliability, and extend the overall service life of the engine.

MAN L21/31; Seal Ring (Code 100100)

Written by

The seal ring, code 100100, is a precision-engineered sealing component used throughout the MAN L21/31 engine to prevent leakage and maintain the integrity of critical mechanical and fluid systems. Installed between mating surfaces or around rotating and stationary components, it creates a reliable barrier against the escape of lubricating oil, fuel, coolant, or compressed air while preventing contaminants from entering the engine. Designed to accommodate vibration, pressure fluctuations, and thermal expansion, the seal ring ensures consistent sealing performance under demanding marine and industrial operating conditions. Manufactured from high-quality wear-resistant and chemically resistant materials, it contributes to improved engine efficiency, lower maintenance requirements, and extended service life of vital engine assemblies.

The cylinder lubricating pump K 72101 is a specialized lubrication component designed to deliver precisely metered quantities of lubricating oil to the cylinder liners and piston running surfaces of the Sulzer ZV40/48 engine. Its primary function is to minimize friction and wear while protecting critical combustion chamber components against scuffing, corrosion, and excessive thermal loading. Engineered for precise dosing and reliable operation, the pump ensures that lubrication is delivered exactly where and when it is required, optimizing oil consumption without compromising protection. Manufactured from durable, wear-resistant materials and precision-machined for long service life, the pump performs reliably under demanding marine and industrial operating conditions. By ensuring effective cylinder lubrication, the K 72101 pump contributes to improved engine efficiency, lower maintenance costs, extended overhaul intervals, and increased operational reliability throughout the engine's service life.
