Slurry pumps used in operations such as coal preparation plants and other wet-plant operations must endure harsh conditions. Efforts to prevent the entry of water and solid contaminants to pump barrels will extend bearing service lives.

The use of automatic lubrication systems to provide a regular purge of fresh grease through the labyrinth seals of pump barrels is a common and proven method of preventing contaminant entry. As the harshness of the operating conditions increases, so too does the importance of the automatic purging.

Pumps which are subjected to regular wash down or which have water impingement to the wet-end labyrinth demand higher labyrinth purge rates.

In addition to seal purging, automatic systems can also be implemented for bearing re-lubrication in order to provide precise and controlled grease delivery, thereby avoiding grease starvation and over lubrication.
