Bosch Rexroth Axial piston variable pump A4VG Series 35 Construction machinery, agricultural machinery, ships, etc.

Features
▶▶ High power density owing to a very high pressure level
▶▶ Integrated auxiliary pump for boost and pilot oil supply
▶▶ Flow direction changes when the swashplate is moved
through the neutral position
▶▶ High-pressure relief valves with integrated boost function
▶▶ Boost-pressure relief valve
▶▶ Through drive for mounting additional pumps
▶▶ High total efficiency
▶▶ Swashplate design
▶▶ Compact design and high power density
▶▶ Especially suitable for use in electronified travel drives
thanks to integrated sensors
▶▶ Supports the cross-linking of motor and machine control
with the travel drive.

Safety instructions
- The A4VG pumps are designed for use in closed circuits.
- Project planning, installation and commissioning of the axial piston units must be carried out by qualified personnel.
- Before using the axial piston unit, please read the corresponding instruction manual in its entirety. It is available from Bosch Rexroth on request.
- During and shortly after operation, there is a risk of burns from the axial piston unit (especially the solenoid). Take appropriate safety measures (e.g. wear protective clothing).
- The characteristics of the axial piston unit may change due to different operating conditions (operating pressure, oil temperature).

Working line ports
· Ports and fixing threads are designed for the maximum specified pressure. The machine or system manufacturer must ensure that the safety factors of the connecting elements and lines meet the specified operating conditions (pressure, flow, hydraulic fluid, temperature).
· Working line ports and function ports are intended for hydraulic lines only.
- The data and instructions contained here must be observed.
- The product cannot be approved as a component in accordance with the general machinery safety concept in accordance with ISO 13849.

Mounting screws
For mounting screws with ISO metric threads to DIN 13 and threads to ASME B1.1, we recommend checking the tightening torques for the respective housing in accordance with VDI 2230.
· Threaded holes of the axial piston unit:
The maximum permissible tightening torque MG max for internal threaded holes is a maximum value and must not be exceeded.
· Locking screws:
For the metal locking screws supplied with the axial piston unit, the required tightening torque MV for the locking screws should be used.
