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

• Pre-Startup Check: Verify oil level in the tank before startup. Use the recommended grade of hydraulic fluid
• Initial Run: After a shutdown of more than 4 hours, allow the pump to run without load for at least 5 minutes before applying pressure
• Regular Monitoring: Consistently check operating parameters like pressure, speed, and oil temperature during work
• Inspection: Regularly check pipe joints and flange connections for tightness to prevent leaks and air ingress
• Oil Cleanliness: Maintain the cleanliness of the hydraulic oil
