💡 Key Difference (VS PV140R1K1T1NMMC)

This is the model you previously inquired about. The main difference between the two lies in the control method:

PV140R1K1T1NMMC: Suffix1K1representPressure Compensation (PC)Control. The pump will automatically adjust its displacement according to the set pressure, suitable for systems that require constant pressure.
PV140R1K8T1NMMC: Suffix1K8representLoad Sensing (LS)Control. Pumps can not only control pressure, but also sense the flow required by the load, and automatically adjust the flow output according to the load demand, thereby achieving more energy-saving effects (power matching).

Simply put,1K8Version ratio1K1The version has an additional load pressure feedback port (LS port), which makes the control logic more complex and energy-efficient.
