Rexroth A4VTG125 Variable Displacement Hydraulic Pump with Closed Loop Design High Power Density and Variable Control for Winches Drives Conveyors

Rexroth Variable Displacement Pump A4VTG | For Winches, Drives, and Conveyors

A4VTG series hydraulic pump is a high-performance, axial piston variable displacement pump, designed specifically for closed-loop hydraulic systems. Due to its unique working principle and performance characteristics, it has a wide range of applications in many fields that require high power density, precise control, and reliability.
Its core application areas are as follows:

1, Main application areas
1. Mobile Machinery&Construction Equipment
This is the most classic application area of A4VTG pump. Among these devices, it is typically used to drive walking systems.
·Hydraulic excavator: As the driving pump of the walking motor, it provides continuously variable speed and strong traction.
·Crawler crane: Drive the crawler to achieve smooth movement and precise positioning.
·Rotary drilling rig: provides power for walking and platform rotation.
·Concrete pump truck: Some models are used for chassis walking drive.
·Large mining dump truck: driving large wheels requires extremely high power output.2. Agricultural Machinery
Reliable static hydraulic drive is required in large and efficient agricultural equipment.
·Large combine harvester: driven walking system that adapts to the speed requirements of different crops and terrains.
·Beet and Potato Harvester: Provides slow and precise movement control.
·Large tractor: Used for front or rear axle auxiliary drive with static hydraulic drive.
3. Material Handling&Port Machinery
·Port container front-end crane: Drive vehicles to move flexibly and accurately in busy docks.
·Heavy duty forklifts and stackers: used for handling large indoor and outdoor goods.
·Loader: Some large loaders adopt a closed loop driven walking system.
4. Special Vehicles&Forestry Machinery
·Forestry harvester: provides stable mobility in rugged forest terrain.
·Snow artillery vehicle: requires stable driving in snowy environments.
·Airport rescue fire truck: requires high-speed and high-power driving.
5. Industrial Applications
·Coiling and unwinding equipment: In the metallurgical and papermaking industries, constant tension control is required.
·Test bench drive: provides precisely controllable loads for other hydraulic components or gearboxes.
·Large rotary drive: drives rotary platforms, such as yaw system test benches for wind turbines.

2, The core functional characteristics of A4VTG pump (closely related to its application)
1. Closed loop design:
·Advantages: High efficiency, small fuel tank, high integration, good anti cavitation characteristics, especially suitable for continuous working walking machinery.
·Comparison: Compared with open circuit pumps, it comes with a built-in oil replenishment pump and integrated valve block, making the structure more compact.
2. Variable control:
·The displacement can be infinitely varied between maximum and minimum, thereby achieving stepless speed adjustment of the actuator (such as hydraulic motor) and saving energy.
3. High power density:
·With relatively small volume and weight, it can output high power, making it very suitable for mobile devices with limited space.
4. High voltage capability:
·Capable of continuous operation under high-pressure conditions (usually up to 400-450 bar), providing strong torque output.
In summary, the A4VTG hydraulic pump is the core power component of the static hydraulic drive system for large and heavy mobile equipment, especially those that require driving and walking functions. Its application scenarios almost revolve around fields that have extremely high requirements for space, efficiency, control performance, and reliability.
