Customer Case

System: Marine Diesel Engines

Hydraulic control of the injection pumps and exhaust valves of the main engines (2-stroke diesel engines).

Engine: MAN 12K98 ME-C6
Oil type: Lubricating oil, Mobilgard 300
Viscosity: 111 cSt at 40°C

Solution

Installation of a CJC® Hydraulic Filter 427/81 with CJC® Fine Filter Insert B 427/81 (3 µm absolute) for continuous fine filtration and dewatering of the hydraulic oil (24/7).

Dirt holding capacity: approx. 24 kg
Water absorption capacity: approx. 14.4 l
Filtration degree: 3 µm absolute, retention rate < 1 µm
Filter material: 100% natural fibres

The CJC® hydraulic filter removes particles, water, oil ageing products and acidic components from the oil with high efficiency.

Result

There have been no failures since installation. The convincing results of the filtration (see adjacent table) prompted our customer to install identical CJC® hydraulic filters on more than 24 ships of different classes up to 13,000 TEU.
