Preventing contamination in lubricated equipment starts with new oil. While the concept that new oil is not clean may be shocking to some, it stands to reason when you consider the number of times a lubricant is transferred before it’s put into a machine. For example, when a lubricant is delivered to a bulk tank it may be dispensed from a tanker truck. If the transfer process is not a closed system, then airborne particulate may enter the lubricant and storage tank. The same concept applies when a lubricant is dispensed from the bulk storage tank to a transfer container or satellite storage area. To minimize this risk of contamination, an enclosed transfer system is desirable. This is achieved through addressing storage and handling practices, component modifications, and transfer protocol at every point in the Plant Lubrication System.
