4 Ways Outside Contaminants Enter Your System

Posted by Scott Howard on Thu, Feb. 15, 2018

As an equipment owner or manager, the last thing that you want to find in your system is contamination. After all, that means downtime, which ultimately costs you time and money. Contamination always somehow sneaks its way into our systems, which may leave you asking, how does it get in there and what are we supposed to do about it?

[Video] Your Lab Reports Are Probably Wrong -- Here's How To Save Them

Posted by Scott Howard on Tue, Aug. 16, 2016
When looking at a lab report, it is assumed the information on the report is accurate. A certified lab will not usually make an error in the report, but if so, it is obvious and easily fixed. Ever hear the saying "By the time the lab gets the report the error has already been made"? For the most part, this is true. Where people are led off course is believing the particle count on the lab report is the gospel. This is natural, but unfortunately not always the case with a bottle sample unless you already employ the techniques listed in the video below.

Why You Need to Care About Micro-Dieseling

Posted by Scott Howard on Mon, Jan. 27, 2014

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.

Phosphate Ester Acid Remediation

Posted by Scott Howard on Mon, Jan. 20, 2014

Phosphate ester hydraulic fluid has a tendency to become very acidic. As we’ve discussed previously, this acid can cause damage to seals throughout the system and lead to electrokinetic wear (and failure) in valves.

What is a Vacuum Dehydrator?

Posted by Scott Howard on Mon, Sep. 30, 2013

If the hydraulic, lubricating, compressor or gear oil you use is not made of a water base in formulation , then water is considered a contaminant and must be recognized and managed. 

There are three types of water in a typical system: free water , emulsified water and dissolved water. The water saturation point of most oil, that point above which water is in a free form, is 200-400ppm, depending on age and condition. 

Using 100ppm for an upper water limit for most systems using mineral base oils, this means all free and emulsified water and a significant portion of dissolved water must be removed.

A vacuum dehydrator is one of the very few methods to remove dissolved water from oil. Let's take a look at these three types of water in your system. It will give you a solid foundation for how the vacuum dehydrator works in the end.

Why You Need Proper Filtration in Front of Your Control Valves

Posted by Scott Howard on Mon, Sep. 23, 2013

Most people have at least heard the term control valve, even if they don't know exactly what it does. For those of you caring for hydraulic systems, you likely work intimately with these parts. Did you know that if you're not using proper filtration in front of said control valves that you're likely doing your operation a disservice? (It's true.)
