Industrial engines are constantly evolving and the world’s largest producers invest enormous resources in research and development; therefore manufacturers of seals are required to provide new materials and solutions to meet the new demanding requirements.

In recent years, research in this area has been greatly influenced by: Economic factors Fuel consumption has always been considered a substantial cost in the operation of the engine. The development of new engines that are cheaper to operate thanks to the use of gas, bio diesel or fuel blends put a strain on the seals. Technological factors The use of new fuels, the evolution of injection systems, the development of turbochargers and all the structural modifications made to improve the performance of the engine, demand a quick adaptation of the seals. Lubricating oils, coolants, corrosion inhibitors...

Marine Engineering PROPULSION SYSTEMS The field of marine propulsion systems relates to a series of mechanical devices that ensure the distribution of power from the engine to the propeller, as well as the direction and movement of the vessel in port In this context we also note: • Propeller main shaft • Azimuth and tunnel thrusters • Propeller blades • Rudders and steering gear • Roll fin stabilisers Each of these systems is equipped with gearboxes, bearings, locking flanges supported by their seals. The integrity of the entire propulsion system of a vessel is ensured by the use of efficient...

Marine engineering - Seal characteristics In order to retain lubricant within the bearing shaft and therefore prevent seawater from coming into contact with any device or with parts of the engine, causing severe damage, it is critical to carefully choose sealing systems with suitable materials and correct profiles. Seals should serve to • Protect the devices from seawater ingress • Extend the life of the bearing • Significantly reduce maintenance costs and downtime • Avoid waste or loss of lubricant and related costs Reduce power consumption and ensuring low friction running Prevent the corrosion...
