Some Tips on Improving Lubricant Cleanliness

As a best practice, it is recommended that oils must be filtered while these are being transferred from one container or machine to another. Doing so can improve cleanliness of lubricants with just a single pass.  The expected level of cleanliness can also be achieved by using filters with a beta ratio greater than 200 at the right micron size. Usage of highly efficient filters will call for proper lubricant rate and pressure based on the viscosity as well as volume to be filtered.

A low-cost option to eliminate solid contaminants, therefore cleaning oils in a machine or container, would be installation of a temporary online filtration system also known as a “kidney loop”. As the lubricant goes back to the same catch basin from which it was obtained, it is combined with non-filtered lubricant. The new sump cleanliness is the product of mixed concentrations. This is the reason why oils must flow through the filter multiple times. The number of passes relies on the existing and desired level of cleanliness as well as on the volume of available lubricant.

Application of modern centrifugal technologies can also help in cleaning oils. Employment of these can be extremely efficient in taking out solid contaminants and enhancing ISO cleanliness codes. These centrifugal technologies are used for industrial engine oils and are commonly applied as a bypass system for the main filtration and lubrication track.

Other alternatives that can help clean lubricants include gravity settling or magnetic filters although these are not as effective when it comes to removing various materials or tiny particles.

Achieve longer equipment life by controlling oil cleanliness with quality filtration products as well as specially formulated lubricants.
