Key points for selecting Rexroth piston pumps of the A2FO series

Thread Content

To select a Rexroth A2FO series plunger pump, it is necessary to carry out some preparatory work first – that is, to understand the various parameter characteristics of the Rexroth A2FO series of plunger pumps. The data compiled by Autos are as follows: Series: Rexroth A2FO series plunger pumps; Specifications: 10, 12, 16, 23, 28, 32, 45, 56, 63, 80, 90, 107, 125, 160, 180, 200, 250, 355, 500, 710, 1000. Series 6. Working pressure: Rated pressure of 35 MPa, peak pressure of 400 MPa. Characteristics: – Slant-axis axial positive-displacement pump suitable for hydrostatic drive in open circuits； - Suitable for walking machinery or industrial applications ； - The output flow is proportional to the drive speed and displacement ； - The design of its drive shaft bearings ensures the desired service life in the application areas ； - Multiple specifications can be matched to each actual drive ； - Favorable power-to-weight ratio ； - Compact design, cost-effective ； - Best volumetric efficiency ； - Integrated plunger design with a plunger ring. Safety instructions: – The A2FO pump is designed for open-loop systems. – The project planning, installation, and commissioning of axial piston units must be carried out by qualified personnel. – Before using the axial piston unit, please read the corresponding instruction manual thoroughly. It can be obtained from Bosch Rexroth if necessary. – During operation and shortly after, the axial piston unit poses a risk of burns. Appropriate safety measures should be taken (such as wearing protective clothing). – The characteristics of the axial piston unit may change depending on different operating conditions (operating pressure, oil temperature). – Working line oil port: · The oil port and fixing thread are designed for the maximum specified pressure. Machine or system manufacturers must ensure that the safety factors of the connecting components and pipelines meet the specified operating conditions (pressure, flow rate, hydraulic oil, temperature). · The working line oil ports and functional oil ports are used only for hydraulic lines. – The data and instructions contained here must be followed. – This product cannot be approved as a component that adheres to the general mechanical safety concept of ISO 13849. – A relief valve will be installed in the hydraulic system. – Use the following tightening torques: · Joints: For the tightening torque of the joints used, please refer to the manufacturer’s instructions. · Mounting bolts: For mounting bolts with ISO metric threads in accordance with DIN 13 standards and threads in accordance with ASME B1.1 standards, we recommend checking the tightening torque for each housing according to VDI 2230. · Threaded hole of the axial plunger unit: The maximum allowable tightening torque MG max applies to the threaded hole; this value must not be exceeded. · Locking screw: For the metal locking screw provided with the axial plunger unit, the tightening torque MV required for the locking screw shall be used.
