What causes contamination? Particulate contaminants circulating in fluid power systems cause surface degradation through general mechanical wear (abrasion, erosion, and surface fatigue). Dan Zoller, Group Product Manager Filter Systems, Schroeder Industries, explained that this wear causes increasing numbers of particles to be formed, the result … [Read more...]
What is oil sampling?
Hydraulic fluid will have innate properties originating from its base stock, but will also contain additives to improve performance factors such as lubricity, corrosion protection, viscosity index and water saturation, to name a few. If a high quality hydraulic fluid came from the factory with excellent properties, how can we guarantee that oil … [Read more...]
What is automatic particle counting?
Automatic particle counting is a key to keeping track of fluid cleanliness in within a hydraulic system. Dan Zoller, Group Product Manager Filter Systems at Schroeder Industries says that a common practice has been to take oil samples from the system and have them sent to a lab for analysis, or evaluated on site by hand (e.g. Patch test with … [Read more...]

They key to a cost effective preventive maintenance plan are tools that will prevent big leaks before they happen. The Spectroline OPK-441 Industrial Leak Detection Kit is a starter kit designed to pinpoint the exact source of even the smallest leaks in hydraulic equipment, compressors, engines, gearboxes and fuel systems. The kit features … [Read more...]
OxiStop tank prevents contamination and cavitation
Any hydraulic system user must take contamination and cavitation prevention seriously, as these two activities can severely damage components and machinery. One such answer to these problems is HYDAC's OXiStop LID series, a tank solution for hydraulic systems with an integrated, hydraulically driven degassing and dewatering unit. It is designed … [Read more...]
The importance of fluid power contamination control
Contamination is widely recognized as the leading cause of premature failure in fluid-power systems. Thus, keeping contaminants in check helps ensure components and systems perform as intended and last a long time, with minimal unscheduled downtime. Heed the following advice for proper fluid power contamination control. Contamination comes in … [Read more...]
Off-line Filtration
Are there specific types of off-line filtration which are increasingly used? If so, why? Yes, we see that the demand for mobile units with integrated sensors is growing. Experienced maintenance and service employees nowadays are aware about the fact that off-line filtration reduces the operating costs of hydraulic machines. Additionally, more and … [Read more...]

MV-HO Hydraulic Oil is a petroleum-based multi-viscosity, anti-wear hydraulic oil designed especially for high speed, high pressure, mobile equipment service, and machine tool applications. Special Low Pour Hydraulic oil is suitable for heavy duty, high pressure applications. Its anti-wear characteristics make it ideal for high performance in … [Read more...]
Where are filtration systems used?
Filtration systems are used anywhere upgraded or auxiliary filtration is required in a hydraulic system. A filtration system is available in either permanent kidney loop circuits or portable filter cart assemblies. Either system is used to improve the cleanliness of the hydraulic fluid in a hydraulic machine. Often, filtration systems are used to … [Read more...]
Where are hydraulic filters used?
Illustration shows a high-performance filter element. Photo courtesy of Pall Corp., 2015. Hydraulic filters are used anywhere in a hydraulic system particle contamination is to be removed. Particle contamination can be ingested through the reservoir, created during the manufacture of system components, or generated internally from the hydraulic … [Read more...]
