Danfoss Sauer FRR/FRL 074B 090C GRR/GRL Piston Pump LS BS LB PC BC FE

1. Product Overview

Danfoss SaoFRR/FRL seriesIt is specifically designed forMobile equipmentDesignOpen-loop axial piston pump。

This series typically adoptsLoad-sensitive (LS)Control, which can automatically adjust flow and pressure according to system requirements, is the core component for achieving energy saving and precise motion control.

2. Core Features

• Load-Sensitive Control (LS)Standard configuration includes LS control, which prioritizes oil supply to circuits with low load pressure, significantly reducing overflow losses and system heat generation.

  
  

• Multiple control modes:supportPC(Pressure cut-off)BC(Constant power)FEMultiple composite controls, such as electro-proportional control, are available to adapt to complex working conditions.

  
  

• High power densityIt has a compact structure, provides a large displacement in a limited space, and is suitable for installation in narrow engine compartments.

  
  

• Excellent impact resistanceIt features a reinforced design to withstand severe vibrations and impacts on mobile machinery, resulting in high reliability.
