Rexroth A11VO75 A11VO90 Pump
product overview -Model: A11VO75 -Type: Diagonal disc axial variable displacement piston pump -Displacement: 75 cm ³/rev (milliliters/rev) -Design: Open circuit, suitable for variable flow requirements in hydraulic systems.
Core Features
-Variable adjustment:
-Adopting pressure flow control (such as LR, LRDS, etc.), the output flow is automatically adjusted to adapt to changes in system pressure, achieving energy conservation.
-Optional control modes include constant power (HP) and constant voltage (DP).
-High efficiency:
-High volumetric efficiency, reducing energy loss, suitable for long-term high load operation.
-Low noise: Optimized design to reduce operating noise, in line with modern industrial environmental requirements.
-Durability:
-High strength materials and precision machining, strong anti pollution ability, long service life.
-Suitable for high pressure (up to 350 bar, depending on the specific model).
Technical parameters (typical values)
-Displacement: 75 cm ³/rev
-Rated pressure: 280 bar (peak value 350 bar)
