Advancements in Fluid Analysis Technologies and Strategies for Hydraulic SystemCondition-Based Maintenance
World-class condition monitoring of hydraulic systems involves the successful integration of a number of strategic elements. While in the past, walk-around inspections and gage data were the primary means of monitoring system health, today’s modem oil analysis programs apply a host of sophisticated new tools and instruments.

What is Your Oil’s Impurity-holding Capacity (IHC)?
There has been much said in recent years about the increased propensity of some modern oil formulations to produce sludge and varnish. Ironically, many of the oils accused of contributing to varnish are the same oils endowed with exceptionally high oxidation stability due to advanced refining technology and formulation science.

Sludge and Varnish in Turbine Systems
The products of lubricant degradation are called sludge and varnish. These products start in the dissolved form and accumulate until the lubricant reaches its capacity, referred to as the saturating point, forcing any excess to convert into insoluble degradation products. Read More

Recognizing the Causes and Hazards of Silt Lock
Do you know about silt lock? This common condition causes motion impediment failure in certain machines. While this type of failure usually doesn’t involve wear or permanent internal damage to the machine, it is sudden and abrupt. Read More
