Product Description

	Series	A4VG_32Series high pressure plunger pump
	Specifications	28、40、56、71、90、125、180、250
	Work stress	Nominal pressure 40MPa, peak pressure 45MPa
Control method: NVType, no control device DG-Hydraulic control, direct control THIS-Electrical two-point control, with switch electromagnet HD-Hydraulic control, related to pilot pressure HW-Hydraulic control, mechanical servo EP-Electrical control, with proportional electromagnet YES-Hydraulic control, related to deceleration	Characteristics	◆ Swash plate type axial piston variable displacement pump for closed circuit hydrostatic transmission The flow rate is proportional to the driving speed and displacement and can be stepless variable; The flow rate increases from zero to its maximum value with the swash plate swing angle; ◆ Make the swash plate swing through the middle can smoothly change the flow direction of the liquid flow; ◆A variety of variable modes that are easy to match with various control and regulation 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 the oil valve; The built-in auxiliary pump is used as the fuel supply pump and control pump; ◆ The maximum oil filling pressure is limited by a built-in oil filling overflow valve; ◆ Full series with built-in pressure shut-off valve;

PeaceFull Description

-A4VG pumps are designed for use in closed circuits.

-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 in its entirety. If needed, please contact Bosch Rexroth.

-There may be a risk of burns to the axial plunger unit (especially the electromagnet) during and shortly after operation. Appropriate safety measures should be taken (e.g., wearing protective clothing).

-The characteristics of the axial piston unit may vary depending on different operating conditions (working pressure, oil temperature).

-Working circuit port:

· Oil port and fixed thread are designed for maximum specified pressure. Machine or system manufacturers must ensure that the safety factors of connecting components and pipelines meet the specified operating conditions (pressure, flow rate, hydraulic fluid, and temperature).

· The working line ports and functional ports are only used for hydraulic lines.

-The data and instructions contained herein must be followed.

-The product cannot be approved as a component following the general mechanical safety concept of ISO 13849.

-The following tightening torques are applied:

· Joint:

See manufacturer's instructions for tightening torque of the joint used.

· Mounting bolt:

For mounting bolts with ISO metric threads in accordance with DIN 13 and threads in accordance with ASME B1.1, we recommend checking the tightening torque of each box according to the VDI 2230.

· Threaded hole of axial plunger unit:

The maximum allowable tightening torque MG max is the maximum value for internally threaded holes and must not be exceeded.

· Locking screw:
For metal locking screws supplied with the axial plunger unit, the tightening torque MV required for the locking screw shall be used.
