About 15 years ago, I added a new file to my library of technical literature – a folder into which I put a single magazine article on flushing procedures. Today the file is bulging with papers, articles, procedures and industrial standards on this single subject.
When you consider the large number of machine types in use, each with special needs and the unique problems that flushing must restore to a clean and healthy state, it is no wonder that so many different approaches and technologies have been deployed.
Both service and equipment suppliers continue to offer new answers to the age-old problem of how best to purge contaminants and lubricant degradation products from the bowels of the machine.
