characteristic
◆Swash plate type axial piston variable pump, used for closed circuit hydrostatic transmission
◆The flow rate is proportional to the driving speed and displacement and can be infinitely variable;
◆The flow rate increases from zero to its maximum value with the swing angle of the swash plate;
◆Swing the swash plate through the neutral position can change the direction of liquid flow smoothly;
◆Various variable modes that are easy to match with various control and adjustment systems;
◆The pump is equipped with two relief valves on the high-pressure oil side to protect the hydrostatic transmission (pump and motor) from overload;
◆The high-pressure relief valve also has the function of a supplement valve;
◆Built-in auxiliary pump is used as charge pump and control pump;
◆The highest replenishment pressure is limited by a built-in replenishment relief valve;
◆The whole series has built-in pressure shut-off valve;
 

 safety instructions
-The A4VG pump is designed for use in closed circuits.
-Project planning, installation and commissioning of the axial piston unit must be carried out by qualified personnel.
-Before using the axial piston unit, please read the corresponding instruction manual completely. If necessary, it can be obtained from Bosch Rexroth.
-During and shortly after operation, the axial piston unit (especially the solenoid) may be at risk of causing burns. Appropriate safety measures (such as wearing protective clothing) should be taken.
-The characteristics of the axial piston unit may change due to different working conditions (working pressure, oil temperature).
-Working line oil port:
· The oil port and fixed thread are designed for the maximum specified pressure. The manufacturer of the machine or system must ensure that the safety factors of the connected components and pipelines meet the specified working conditions (pressure, flow, hydraulic oil, temperature).
· Working line oil ports and functional oil ports are only used for hydraulic lines.
-The data and instructions contained herein must be followed.
-The product cannot be approved as a component that complies with the general machinery safety concept of ISO 13849.
-Use the following tightening torques:
· Connector:
Refer to the manufacturer's instructions for the tightening torque of the joints used.
· Installation bolts:
For mounting bolts with ISO metric threads that meet DIN 13 standards and threads that meet ASME B1.1 standards, we recommend checking the tightening torque of each box according to VDI 2230.
· The threaded hole of the axial plunger unit:
The maximum allowable tightening torque MG max is the maximum value for internal threaded holes, and must not exceed this value.
· Locking screw:
