Description

Technical Parameters

A4VG series is swash-plate axial pistonvariable-type pump.It is used for hydrostatictransmission in closed circuits.The flow isproportional to the driving speed and displacementThe output flow increases from zero to maximumwith the swash plate swing Angle.It providesa variety of control and regulation functionsfor various of high compatibility controlequipment.Two overflow valves which are equippedon each side of the pump are used to preventthe static hydraulic drive (pump and motor)fromoverload,and also have the function of filling oil.

As the supplier of transmission and control technology, Bosch Rexroth introduces the A4VG-40 series of axial piston pumps for hydraulic transmission. With its compact shape design, practical power control, and stability advantages, the product has become a solution for walking machinery such as concrete machinery, road machinery, and flat transport vehicles.

Stable performance concrete pump truck is a modern concrete construction equipment integrating driving, distributing and pumping functions, which can be widely used in transportation, energy, hydropower, construction and other fields. How to improve work efficiency while ensuring construction safety has always been a big problem in the industry. Bosch Rexroth A4VG-40 series axial piston pump can help the pump truck reduce pressure loss and reversing impact, reduce hydraulic oil consumption, and improve the stability of the boom.

A4VG-40 series axial piston pump through the integration of pump body and control module and the new rotary body design, the rated working pressure is increased to 45 MPa(peak pressure can reach 50MPa); The high power density reduces the volume and mass of the wave pressure cylinder, which can meet the requirements of ultra-high pumping and high grade concrete pumping. The rapid reversing function of the high-pressure hydraulic pump can effectively solve the great challenge of the ultra-long boom to the pumping stability.
