Rexroth A2FO56 Series 350MPA Maximum Load 250L/min Speed Regulation 180-680 Test Scope Hydraulic Piston Pump

A: The A2FO56 is a series of fixed displacement axial piston pumps with a swash plate design (specifically, a "bent-axis" design with a conical piston rotor assembly) intended for use in open circuit hydrostatic drives. They are suitable for both mobile and stationary applications.

• High Power Density: Provides substantial power output relative to its size.
• Compact Design and Small Dimensions: Saves space in equipment design.
• High Overall Efficiency: Contributes to energy savings.
• Robust Bearing Design: The drive shaft bearing is designed to meet the service life requirements of demanding applications.
• One-Piece Piston with Piston Ring Seal: Contributes to reliable performance.
• Economic Design: Offers a cost-effective solution.

• Geometric Displacement per Revolution: 56.1 cm³/rev
• Rated Pressure: 35 MPa (350 bar)
• Peak Pressure: 40 MPa (400 bar)
• Speed Range: Approximately 500 to 3500 rpm (dependent on specific model and pressure)
• Flow Rate: Proportional to drive speed and displacement; approximately 112 L/min at nominal speed (e.g., 2000 rpm) and Δp=350 bar.
• Mass: Approximately 18 kg.
