Product Specification

Bosch Rexroth Axial piston variable pump A15VS(L)O Series11 Construction machinery, agricultural machinery, forestry machinery

For more detailed parameters of A15VS(L)O and other models, please contact our sales staf

Features
▶ Variable pump with axial piston rotary group
in swashplate design for hydrostatic drives in open
circuit.
▶ For use particularly in industrial application areas
▶ Flow is proportional to the drive speed and
displacement.
▶ Flow can be infi nitely varied by controlling the
swashplate angle.
▶ The pump can work either self-priming or with
a charge pump.
▶ Special control device program for industrial
applications, with diff erent control and regulation
functions.
▶ The universal through drive is suitable for adding gear
wheel pumps and axial piston pumps of up to the
same size, i.e. 100% through drive.
▶ Compact design
▶ High effi ciency
▶ High power dens

Safety instructions

- Pump types A15VSO and A15VLO are designed for use in open circuits.

- Project planning, installation and commissioning of axial piston units require the involvement of skilled personnel.

- Before using an axial piston unit, please read the corresponding instruction manual in its entirety. It is available from Bosch Rexroth on request.

- The characteristics of the axial piston unit may change due to different operating conditions (operating pressure, oil temperature).

- Working line ports:
• The ports and fixing threads are designed for the maximum specified pressure. The machine or system manufacturer must ensure that the safety factors for the connecting elements and lines meet the specified operating conditions (pressure, flow, hydraulic oil, temperature).
• The working line ports and function ports are intended for hydraulic lines only.
- The data and instructions contained here must be observed.
- Before finalizing your design, please request the binding installation drawing.
- Not all versions of this product are approved for safety functions according to ISO 13849. For reliability parameters (e.g. MTTFd) regarding functional safety, please consult your responsible contact at Bosch Rexroth.
- The pressure controller is not a backup device in the event of pressure overload. A separate pressure relief valve should be installed in the hydraulic system.
- The following tightening torques apply:
• Fittings:
Observe the manufacturer's specifications for the tightening torques of the fittings used.
• Mounting screws:
For mounting screws with ISO metric threads in accordance with DIN 13 and threads in accordance with ASME B1.1, we recommend checking the tightening torques of the respective housing in accordance with VDI 2230.
• Threaded holes of the axial piston unit:
The maximum permissible tightening torque MG max for the threaded holes is a maximum value that 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 apply.
