The A17FO32, A17FO45, A17FO63, A17FO80, A17FO107, and A17FO125 hydraulic pumps are a series of axial piston variable displacement pumps produced by Rexroth (a German company). Below is a detailed introduction to these models:
I. Product Overview
• Brand and Model: Rexroth A17FO series hydraulic pumps, including models A17FO32, A17FO45, A17FO63, A17FO80, A17FO107, and A17FO125.
• Design Features: Utilizes an axial piston bent-axis design, characterized by compact structure, high efficiency, and long service life.
• Application Areas: Widely used in hydraulic drive systems of equipment such as commercial street dump trucks, heavy-duty truck loading cranes, oil tankers, municipal vehicles, and special-purpose vehicles.
II. Technical Parameters
• Size: The sizes of the pumps vary among different models, with A17FO32 being relatively smaller and A17FO125 being larger.
• Displacement: The displacement varies for each model, e.g., A17FO32 may have a displacement of 32 cm³/rev, while A17FO45 has a displacement of 45.6 cm³/rev, and so on.
• Pressure:
• Nominal Pressure: The nominal pressure of the A17FO series pumps is typically 300 bar (or 30 MPa), with some models like the A17FNO series having a nominal pressure of 250 bar.
• Peak Pressure: The peak pressure can reach up to 350 bar (or 35 MPa), meeting the demands of high-pressure hydraulic systems.
• Speed: The speed range varies among different models, but they generally operate within a high-speed range, e.g., the maximum speed of A17FO32 may be 2920 rpm, while that of A17FO125 may be 1800 rpm.
• Flow Rate: The flow rate is proportional to the speed and displacement, with a wide range of flow rates available to meet the needs of different hydraulic systems.
III. Performance Characteristics
• Energy Efficiency: Adopts advanced variable control technology to automatically adjust displacement based on load requirements, achieving energy-efficient operation.
• Long Service Life: Key components are made of high-quality materials and undergo precision machining and special treatment, resulting in a long service life.
• High Reliability: Reasonable design and compact structure reduce failure points, enhancing system reliability.
• Easy Maintenance: Modular design facilitates quick and easy maintenance, reducing maintenance costs and downtime.
IV. Application Examples
• Commercial Street Dump Trucks: The A17FO series pumps provide stable and reliable hydraulic power for dump trucks, ensuring their normal operation.
• Heavy-Duty Truck Loading Cranes: In heavy-duty truck loading cranes, the A17FO series pumps are used to drive the hydraulic system, enabling the lifting and handling of heavy objects.
• Oil Tankers and Municipal Vehicles: The A17FO series pumps are also widely applied in the hydraulic systems of oil tankers and municipal vehicles, providing efficient and reliable hydraulic power for these equipment.
