Hydraulic Library

When I created the Library section, I was going to combine a nice page with links to hydraulic manufacturer web sites and short descriptions. However, it occurred to me, that it's sort of offensive to tell people to look for Rexroth products at, or Enerpac at It's almost like telling someone they find Googling for information a mental challenge...

Then I had an idea of uploading a bunch of catalogues (I have a HUGE technical library, and look for increasing it in any way I can...) but again, due to copyright issues and the fact that most of the files were taken from the web, I would be just creating a mirror site, which is a waste of my time.

I wouldn't want to call people obtuse and, of course, I can not afford wasting my time on uploading files available online at source sites, so the Library, so far, only contains articles and links to articles/sites, which I personally have found extremely interesting or useful.

Still, If anybody feels like there are copyright issues, do contact me, and we shall deal with it.

Interesting and Usefull Stuff

Gear Pump Displacement Calculator - an App that I wrote to make my life easier. It calculates external gear pump displacement and allows you do download the data in a nice pdf file. More about gear pump displacement calculation here.
