Filter carts are mobile kidney loop systems that contain a motor, a pump and a filter to form an independent unit. Filter carts can generally be used in two different ways: as enhancement to existing hydraulic system filters, and as fluid preparation for use in hydraulic systems after an event (e.g. replacing fluid, repairs, maintenance, […]

The primary objective for developing ARGO-HYTOS’ EXAPOR MAX 2 filter element was greater machine availability, longer service intervals, lower-cost spare parts, and lower operating costs for machine operators in the area of mobile and industrial hydraulics. To improve the performance density of the filters, ARGO-HYTOS engineers took a closer look at the conditions in the fold […]

In a recent blog, “A nanoscale view of hydraulic fluids,” we related how researchers at the University of California, Merced and the Milwaukee School of Engineering are working to better understand the fundamentals of hydraulics fluids on the molecular level, and how that might lead to more-efficient fluid-power systems. A key tool in the research […]

Hydraulic filters are an example of a product that began as a very simple solution but progressed over the years to be quite complex. Jeremy Crookshanks Product Manager, Hydraulic & Lube Filtration for Schroeder Industries said that while they still perform the same basic task of protecting sensitive hydraulic components from contaminates, due to industry requirements, […]

One of our passions here at Fluid Power World is providing you with all your need-to-know engineering information not just in print, but online—whether through traditional websites or via a host of social media platforms such as Twitter, LinkedIn and YouTube. In addition to our main web portal, which features a broad look at fluid…
Oil sampling and analysis is a method of determining and tracking the health of your hydraulic fluid. A oil sample is taken and sent to a lab to discover ISO particle count, water saturation, additive content and viscosity. These qualities in normal range are imperative to a reliable hydraulic system, and sample testing is the […]

Hydraulic systems are generally equipped with system filters. The system filters are either placed on the pressure side (e.g. downstream of pumps, before system components) or on the return side (e.g. before fluid is reaching the reservoir). Dan Zoller, Group Product Manager Filter Systems, Schroeder Industries, said that in a case where only one filter is used, […]

Comprehensive testing of water glycol fluids on common seal materials reveals temperature-related issues. By: James Simpson and Eric Bucci – Trelleborg Sealing Solutions The polyglycol is a water-soluble polymer thickener that can be formulated to cover a wide range of viscosities. The resulting viscosity-temperature properties give water glycols good low-temperature cold-start pump wear protection and…
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 being that wear increases if the “chain reaction of wear” is […]

Solid contamination in hydraulic fluids is subdivided into three groups: extremely hard, hard and soft particles. Dan Zoller, Group Product Manager Filter Systems, Schroeder Industries, explains that extremely hard particles can cause substantial damage in fluid power systems if they are not removed as quickly as possible. Preventive measures can reduce the ingress of contaminants in […]

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 hasn’t lost […]

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…
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…
Just having a hydraulic fluid management plan in place doesn’t mean that you are doing it correctly. Managing your lubrication properly is critical in maintaining clean, efficient hydraulic systems, said Jason Kopschinsky, CMRP, director of reliability services for Des-Case. “Not approaching lubrication in a holistic manner, including lubricant specifications, education, contamination control, preventive maintenance optimization,…
Spectroline Industrial has released the LeakTracker kit for use with hydraulic systems, compressors, engines, gearboxes and fuel systems. It comes with the LT-300 LeakTracker UV leak detection flashlight that delivers pure UV light for superior fluorescent dye response.

ARGO-HYTOS’ return-suction filter offers functional improvements of the return filter and section or pressure filter, such as excellent cold start characteristics, protection of the filling pump, fewer components and reduction of spare parts and maintenance costs. Additional advantages include one filter for both circuits, the total oil volume being filtered in the return line, more…
Most hydraulics users know that fluid contamination leads to problems. It can raise fluid costs, promote premature component failure and cause unscheduled downtime, just to name a few potential headaches. “Over the past 10 years, the knowledge base has widened and customers are more aware that contamination is important and it influences performance and costs.…
Improper fluid levels in a hydraulic system can cause a number of difficult and sometimes even catastrophic failures. For example, having too much hydraulic fluid in the reservoir can cause the reservoir to overflow when a differential cylinder retracts. On the other hand, having too little fluid in the reservoir can introduce air into the…
