Centralized lubrication system for wind turbines offers improved efficiency

SKF has developed a special pump unit that supplies the centralized lubrication system in wind turbines. The main component of the system consists of the KFG pump, an electric filling pump and a pressure switch. Unlike in earlier pump versions, the lubricant can be fed into the modified KFG pump unit from the top, avoiding an accumulation of grease in the upper part of the pump. The modular concept of the new KFG pump is suitable for use in a wide temperature range, enables larger pump designs and is easy to install. The KFG pump unit also contains a new machined sealing concept for the grease follower piston. This new K01-R ECOVAR sealing concept was developed by SKF Economos Deutschland GmbH in cooperation with SKF Lubrication Systems Germany. The KFG pump can be refilled with a specially designed portable electric filling pump, thus significantly improving service and maintenance operations.
