HPU fabrication

We don't typically engage in hyperbole, but we will say that no matter what hydraulic problem you have, we've already been part of the solution.


When you've been in business as long as we have and faced technology's increasingly rapid developments, you learn a few things. Or, in our case, more than a few. We not only have simple, ready-to-implement solutions for almost every problem, we have the experience for them, too. And, if you bring us something new, our engineers would love to work with you to find the solution.


Rig Up Services & Refurb

We remember the old days of black gold like few others. We've seen and been part of every incremental advance of getting the stuff out of the ground – from the first rigs to the most sophisticated underwater solutions of today.

Our certififed technicians are availabe 24hrs a day.  No matter what the issue is we can help!  Our techs can do pump swaps, flush your hydraulic fluid, fix leaks, overheating HPUs, and much more.

If you have hydraulic components and need someone to put all the pieces together, we can help.

At PSI Hydraulics we can build an HPU for any type of application that you might have.  We have built HPUs for dredges, driling rigs, press machines, food processing, industrial plants, flushing, units, and agricultural applications.  We can also refurbish or upgrade your current HPU.
