In a condition-based maintenance environment, the decision to change-out a hydraulic pump or motor is usually based on either remaining bearing life or deteriorating efficiency, whichever occurs first.

Despite recent advances in predictive maintenance technologies, the maintenance professional’s ability to determine the remaining bearing life of a pump or motor, with a high degree of accuracy, remains elusive.

Deteriorating efficiency … Read more

It’s now more important than ever to ensure that every dollar spent on operating and maintaining hydraulic equipment is a dollar well spent. Furthermore, it’s imperative that the hydraulic equipment you design, repair or maintain doesn’t LEAK money.

Hydraulic systems are often considered perennial consumers of oil and in turn, make-up fluid an inherent cost of operating hydraulic equipment. But … Read more

Given that removing contaminants from the oil to extend hydraulic component life is the primary objective of filtration, it is a paradox for filters to be located where they reduce the service life of components they were installed to protect.

So when considering the possible locations for filters in a hydraulic system, the overarching principle should be: first, do no … Read more
