Understanding ISO Codes

By Dustin Flynn on Thu, Feb. 25, 2021

The ISO Cleanliness Code (per ISO4406-1999) is used to quantify particulate contamination levels per milliliter of fluid at 3 sizes - 4µ, 6µ, and 14µ. It is expressed in 3 numbers (example 19/17/14) where each number represents a contaminant level code for the correlating particle size. The code includes all particles of the specified size and larger.Screen Shot 2021-02-23 at 2.50.37 PMIt is important to note that each time a code increases, the quantity range of particles is doubling. Inversely, as a code decreases by one the contaminant level is cut in half.

An Aluminum Refinery Faces Premature Gearbox Oil Changes

By Jim Harlan on Wed, Dec. 14, 2016

The Application

An Australian aluminum refinery was consistently performing premature gearbox lube oil changes on seven base drive units due to oil and particulate contamination.

With an average operating ISO code of 20/18/16 and average water levels of 4742ppm, the 360 liters / 90 gallons of ISO VG320 gear oil was being changed far too often. Cost per gearbox oil change (excluding crane, lost production, labor) is $17,962.60 which adds up to $125,738.20 for all seven units.

Is Choosing a Sample Port Location Driving You Mad?

By Jim Harlan on Mon, Jul. 07, 2014

The ideal sample port location depends on the purpose for drawing the sample. There are several reasons to draw samples from your hydraulic or lube systems. The main reason is to ensure that the fluid traveling through your system is not loaded with contamination that will damage your pumps, valves and other components.

Secondary reasons include identifying components that are beginning to wear before they fail (this allows you to be proactive about the component replacement or repair) and verifying filter element performance. Continue reading to learn where to take a sample from for each of these reasons. We’ve also included some general fluid sampling tips at the end of this blog.

How to Prevent Gearbox Failure

By Aaron Hoeg on Thu, Jan. 17, 2013

When gearboxes go down, it’s generally because of contamination. This is a costly repair on its own, but once you include the loss of production from downtime, the cost can soar to astronomical figures. Sadly, though, sometimes gearbox failure happens, which wastes your time and money. Let’s take a look at some of the main causes of gearbox contamination and how you can prevent it.
