Axial Excavator Piston Pump FRR/FRL Series
Danfoss' FRR series plunger pump is a high-pressure, variable displacement plunger pump widely used in industrial hydraulic systems, mobile machinery (such as engineering machinery, agricultural equipment) and other fields.
Product Features
-Variable design: The FRR series adopts a slanted disc variable mechanism, which can automatically adjust the displacement according to system requirements, achieving efficient control of flow and pressure.
-High pressure capability: The working pressure can reach 350 bar (some models are even higher), suitable for high load applications.
-High efficiency: Optimized design of plunger and distribution plate reduces internal leakage and improves volumetric efficiency.
-Low noise: By optimizing the fluid path and shock absorption design, the operating noise is reduced.
-Modular design: can integrate multiple control methods (such as pressure compensation, load sensitivity, electric proportional control, etc.).
Typical applications
-Industrial equipment such as injection molding machines and die-casting machines.
-Excavators, cranes, concrete pump trucks and other construction machinery.
-Forestry and agricultural machinery (such as harvesters, tractor hydraulic systems).
