| 16 perma lubrication systems STEP 1: Assess application Pumps Slurry pumps used in operations such as coal preparation plants and other wet plant operations endure harsh conditions. Efforts to prevent the entry of water and solid contaminants to pump barrels will extend bearing service life. 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. The harsher the operating conditions, the greater the importance of automatic purging. Pumps which are subjected to regular wash down or which face water impingement to the wet-end labyrinth demand higher labyrinth purge rates.
