With experts estimating that 75% of hydraulic component and system failures are caused by contamination, it is quite clear that hydraulic systems should be assembled with clean parts in a controlled manufacturing environment.

When this is not possible, it is sometimes necessary for the entire hydraulic system to undergo a clean-up process after final assembly to reach the desired roll-off cleanliness level.

A paper by Geoff Grant, Global Product manager of MP Filtri’s CMP division, provides theoretical calculation of the appropriate flushing requirements for hydraulic systems, when a clean-up process after assembly is necessary to guarantee roll-off cleanliness.

Exploring new ISO standards for roll-off cleanliness of hydraulic systems, the various cleaning methods that can be adopted, and the types of filter that can be used for these operations, this paper is a must-read for anyone involved in the specification, purchasing, and installation of hydraulic systems in modern mobile machines.
