What Power Pack is right for me?

Hydraulic power units are used for a broad range of applications from operating control valves in the outback of Australia to raising parking barriers in Siberia. To match this range of applications there are an equally large range of hydraulic systems and products....

How does a simple hydraulic system work?

The science behind hydraulics is called Pascal’s principle. Essentially, because the liquid in the pipe is incompressible, the pressure must stay constant all the way through it, even when you’re pushing it hard at one end or the other. Now pressure is...

What is the difference between absolute and nominal ratings?

Nominal rating usually means the filter can capture a given percentage of particles of a stated size (e.g. 50% @ 10 micron). Absolute rating is the smallest typical particle size retained by a filter media at 98+% efficiency. This is also referred to as the Beta=75 or...

In mobile hydraulics, where is the filter located?

On a mobile hydraulic system, the filter or filters can be located in several different areas based on the system’s design and intended use. The most common locations are: Suction side – a strainer on the end of the pick-up line in the reservoir or a...

What is the difference between ISO and SAE ratings?

There is no significant difference between ISO (International Standards Organisation) or SAE (Society of Automotive Engineering). Both organisations provide test standards to allow the ability to reliably compare published filter ratings among manufacturers.
