Question by: Lynn H on Sep 19, 2025, 10:22 AM
Running a 3.80 displacement on a loader backhoe setup, what's the max pressure this pump can handle before things start going sideways?
Answer by: Customer Support on Sep 20, 2025, 8:21 PM
Rated up to 4060 psi maximum operating pressure, so it's got solid headroom for loader backhoe work. The pressure compensated load sense control helps manage demand efficiently, meaning the pump isn't constantly running at peak pressure unless the system actually needs it. That combination keeps things running smoother and reduces unnecessary stress on the rotating group over time.
