Here’s another Flint Hydraulics Tech Tip: Most hydraulic system users are familiar with the term “flow rate,” but “flow velocity” is just as important. Flow rate is the volume per unit of time, whereas flow velocity is the distance per unit of time. Excessive flow velocity can cause oil aeration, power loss, system overheating and other problems. As a rule, undersized hydraulic plumbing causes excessive velocity. Need help troubleshooting?
