K3V112DT-9C12 Hydraulic Pump Excavator Main Pump Parts r220lc-7 r210lc-7 r215-7c r225lc-7 31N6-1005

In this dynamic video demonstration, we showcase the K3V112DT-9C12 hydraulic main pump in action for excavator models R220LC-7, R210LC-7, R215-7C, and R225LC-7. You'll see real-world performance insights, learn about its three control modes (constant power, LS load sensing, and HP pressure limit), and understand common failure patterns and maintenance practices. Watch as we explain how this axial variable piston pump converts mechanical energy to hydraulic power while protecting your engine and hydraulic system.
