Demulsibility is the ability of oil to separate from water. Oil and water naturally separate because like molecules attract each other. Oil sticks with oil, water sticks with water. Oil is "hydrophobic", or "afraid of water," which is a benefit when it comes to fluids like turbine oil.  ###### Topics: [varnish in hydraulic oil](https://www.hyprofiltration.com/blog/topic/varnish-in-hydraulic-oil) [varnish in turbine oil](https://www.hyprofiltration.com/blog/topic/varnish-in-turbine-oil) [contamination](https://www.hyprofiltration.com/blog/topic/contamination) [water in oil](https://www.hyprofiltration.com/blog/topic/water-in-oil) [dirt](https://www.hyprofiltration.com/blog/topic/dirt) [Phosphate Ester](https://www.hyprofiltration.com/blog/topic/phosphate-ester) [diesel engine](https://www.hyprofiltration.com/blog/topic/diesel-engine) [maintenance](https://www.hyprofiltration.com/blog/topic/maintenance) [steel mills](https://www.hyprofiltration.com/blog/topic/steel-mills) [vacuum dehydration](https://www.hyprofiltration.com/blog/topic/vacuum-dehydration) [rolling mill lubricating oil](https://www.hyprofiltration.com/blog/topic/rolling-mill-lubricating-oil) [filter housing sizing](https://www.hyprofiltration.com/blog/topic/filter-housing-sizing) [micro-dieseling](https://www.hyprofiltration.com/blog/topic/micro-dieseling) [thermal event](https://www.hyprofiltration.com/blog/topic/thermal-event) [ISO 4406](https://www.hyprofiltration.com/blog/topic/iso-4406) [vacuum dehydrator](https://www.hyprofiltration.com/blog/topic/vacuum-dehydrator) [fluid samples](https://www.hyprofiltration.com/blog/topic/fluid-samples) [oil analysis](https://www.hyprofiltration.com/blog/topic/oil-analysis) [metal analysis](https://www.hyprofiltration.com/blog/topic/metal-analysis) [paper mill](https://www.hyprofiltration.com/blog/topic/paper-mill) [hydraulic pump](https://www.hyprofiltration.com/blog/topic/hydraulic-pump) [samples](https://www.hyprofiltration.com/blog/topic/samples) [COD](https://www.hyprofiltration.com/blog/topic/cod) [duplex low-pressure](https://www.hyprofiltration.com/blog/topic/duplex-low-pressure) [gearbox](https://www.hyprofiltration.com/blog/topic/gearbox) [contaminination](https://www.hyprofiltration.com/blog/topic/contaminination) [hydraulic](https://www.hyprofiltration.com/blog/topic/hydraulic) [duplex high-pressure](https://www.hyprofiltration.com/blog/topic/duplex-high-pressure) [cellulose media](https://www.hyprofiltration.com/blog/topic/cellulose-media) [filter elements](https://www.hyprofiltration.com/blog/topic/filter-elements) [filter comparison](https://www.hyprofiltration.com/blog/topic/filter-comparison) [aluminum refinery](https://www.hyprofiltration.com/blog/topic/aluminum-refinery) [lab](https://www.hyprofiltration.com/blog/topic/lab) ###### 3 min read ### [Why You Need to Care About Micro-Dieseling](https://www.hyprofiltration.com/blog/bid/317086/why-you-need-to-care-about-micro-dieseling) By [Scott Howard](https://www.hyprofiltration.com/blog/author/scott-howard) on Mon, Jan. 27, 2014 [![](https://www.hyprofiltration.com/hs-fs/file-315964283-jpg/images/shutterstock_71593009.jpg) ](https://www.hyprofiltration.com/blog/bid/317086/why-you-need-to-care-about-micro-dieseling) Most people are familiar with diesel engines and how they work, which includes a rapid compression of air. When you inject a fuel source, it creates an explosion. Did you know that micro-dieseling is similar? A front-end loader that runs a diesel engine is a macro-level (or big picture) of what it does on the micro (or smaller) level in a hydraulic pump. ###### Topics: [diesel](https://www.hyprofiltration.com/blog/topic/diesel) [thermal event](https://www.hyprofiltration.com/blog/topic/thermal-event) [fuel](https://www.hyprofiltration.com/blog/topic/fuel) [hydraulic oil](https://www.hyprofiltration.com/blog/topic/hydraulic-oil) [contaminination](https://www.hyprofiltration.com/blog/topic/contaminination) ###### 1 min read ### [Eliminating Filter Element Sparking](https://www.hyprofiltration.com/blog/bid/303561/eliminating-filter-element-sparking) By [Hy-Pro Marketing](https://www.hyprofiltration.com/blog/author/hy-pro-marketing) on Mon, Aug. 12, 2013 [![](https://www.hyprofiltration.com/hs-fs/file-222722025-jpg/images/shutterstock_25367476.jpg) ](https://www.hyprofiltration.com/blog/bid/303561/eliminating-filter-element-sparking) Static electricity is an amazing thing. It can cause hairs to stand on end when rubbed with a balloon, which can cause it to then stick to a wall. (It’s a fun trick, especially for kids). Unfortunately, when it comes to interaction with filters, static can have devastating results. ###### Topics: [thermal event](https://www.hyprofiltration.com/blog/topic/thermal-event) [varnish](https://www.hyprofiltration.com/blog/topic/varnish) [NSD](https://www.hyprofiltration.com/blog/topic/nsd) [filter elements](https://www.hyprofiltration.com/blog/topic/filter-elements) [All posts](https://www.hyprofiltration.com/blog/all) ### Featured ### Sign up for updates ## Have a Question for Donaldson Hy-Pro?
