About
25 Years of Getting to the Root of It
When a hydrostatic system isn't performing the way it should, most companies replace parts and hope for the best. At MJ Hydrostatics, we focus on understanding why the problem happened, and solving it for good.
For over 25 years, OEMs, distributors, contractors, municipalities, and end users have relied on MJ Hydrostatics for hydrostatic design, diagnostics, testing, repair, remanufacturing, conversions, and system integration. We're not a large corporation or a faceless service center. We're a dedicated team of hydrostatic specialists who genuinely love this work and take pride in doing it right.
What Makes Us Different?
Customers work directly with experienced technical personnel, not a salesperson, then a product specialist, then an engineer. One team, one point of contact, real answers.
We work on pumps, motors, controls, contamination, heat generation, filtration, warranty issues, recurring failures, and complete hydrostatic system performance. Over the last 25 years, we've worked with hydrostatic systems used in construction, agriculture, industrial, municipal, and specialty equipment applications.
With over 16,000 square feet of specialized shop space, in-house engineering support, and hydrostatic test stands capable of testing units up to 700 horsepower, MJ Hydrostatics provides technical capabilities that go far beyond traditional hydraulic repair and component distribution.
