  • Throughout the first three entries in this series we've discussed the difference in two filter element testing methods, ISO16889 and DFE. We've also illustrated how many elements fall short of their stated beta ratio under dynamic flow conditions. Today we'll wrap it up with simulated cold start tests. DFE Multi-Pass: Cold Start Contamination Retention Once the element has captured e...

  • Last week we covered the differences between the ISO16889 Filter Test Procedure and the DFE Filter Test Procedure. This week we illustrate the difference between elements engineered to retain particles during dynamic flow conditions and those that are engineered only to pass the ISO16889 test. Quantifying Contaminant Capture and Retention Figure 2 compares the performance of two iden...

  • Last week we briefly discussed how filter elements are rated by manufacturers. This week we're discussing the industry standard ISO16889 multi-pass test and Hy-Pro's standard, the DFE test. Current Filter Performance Testing Methods To understand the need for DFE it is important to understand how filters are currently tested and validated. Manufacturers use the industry standard ISO1...

  • The Dynamic Filtration Efficiency (DFE) Test is Hy-Pro's standard for testing filter elements. Throughout this 4 part series we'll discuss what it is, why it matters and why elements engineered with this test in mind outperform others in real-life applications. First, let's start with the basics... Why are filters used? How are they rated? All hydraulic and lube systems have a criti...

  • DFE Rated Filter Doubles Element Life, Cuts Contamination Levels in Half The Problem A paper machine was experiencing excessive down time as maintenance personnel was frequently servicing a Brand X filter element installed on the lube system. The element would reach terminal ∆P and require replacement every 8.5 days on average.

  • Saves >$15,000,000 by removing water and particulate from common reservoir lube oil. The Application In boiler water feed pump applications, water often finds its way into the oil lubricating the pump’s bearings. This was the scenario at a paper manufacturing facility that turned to Hy-Pro for help. The Problem In this application, the boiler water feed pump bearing lube system w...

  • Saves >$200K/year by reducing downtime, defective units, idle labor and oil costs. The Application During the manufacturing process of refrigerators, isocyanate is hydraulically injected into the body of the appliance to improve insulation. After injection, the chemical transforms from liquid to foam.

  • The Problem Pumps are the heart of hydraulic systems. When the pump fails, the entire system is down until the pump is operational again. This poses a serious threat to any operation relying on hydraulic systems for productivity. Recently, a hydraulic valve manufacturer was losing 25 pumps a year on their centralized hydraulic system at a cost of $2,440 each. That’s only the pump cost...

  • The Problem Today’s oil suppliers are often required to provide fluid at or below a specified ISO Cleanliness Code. One such supplier was experiencing short filter element life (15 days) on the system (7 element multi-round housing) used to achieve the required ISO Cleanliness Code of 18/16/13 in a single pass as 15W-40 oil is transferred from their bulk storage tanks to tanker trucks...

  • Sheet Metal Stamping | Automotive Manufacturing

    The Application An automotive stamping plant operating large presses to produce body panels was experiencing high surface finish defect scrap. Lubricating oil contamination was causing surface imperfections that would be visible after painting. The Problem The uncoiler / washer lube oil system was protected by an off-line filtration system fitted with CJC stacked disc cellulose medi...

  • Gearbox Lube Oil - Aluminum Refinery

    The Application An Australian aluminum refinery was consistently performing premature gearbox lube oil changes on 7 base drive units due to oil and particulate contamination. With an average operating ISO code of 20/18/16 and average water levels of 4742ppm, the 360 liters / 90 gallons of ISO VG320 gear oil was being changed far too often. Cost per gearbox oil change (excluding crane, ...

  • Hydraulic Valve Performance Test Stands & Clean Oil

    The Application A hydraulic valve manufacturer required pristine fluid (< 14/12/9) to test flow across an 80 micron orifice on their test stand. Gross amounts of contamination in the fluid would skew the test results, invalidating any data collected. The system held 100 l (26.4 gal) of ISO VG 32 fluid with a flow rate of 25 lpm (6.6 gpm). Through observing the manufacturer’s sampling...
