Rexroth A4VTG: Premium V‑Groove Twin Gear Hydraulic Pump for High-Pressure, High-Flow Applications
The Rexroth A4VTG High Performance Hydraulic Pump is a V-groove twin gear pump designed for applications where high pressure and flow are required. The Rexroth A4VTG High Performance Hydraulic Pump is available in a 1:1 drive configuration, meaning that the motor has one tooth for every gear tooth, like a worm gear reducer. The Rexroth A4VTG High Performance Hydraulic Pump is available in various sizes and materials.
The Rexroth A4VTG High Performance Hydraulic Pump consists of two gears rotating in opposite directions that mesh together to form a single impeller with the same number of teeth on each gear. This design allows for high torque at low speeds and high flow at high speeds while maintaining a small footprint.
The A4VTG is a variable pump with axial piston swash plate design.
The A4VTG is a variable pump with axial piston swash plate design. It can be used as a hydraulic pump for various applications such as agricultural machinery, construction machinery and mobile equipment.
The A4VTG is available in sizes from 1/2 to 3/4 inch displacement and 10 to 25 horsepower at 2500 RPM. The pump has an open circuit pressure of 3000 psi and maximum flow of 900 gpm at 100 psi differential pressure. It has a maximum operating temperature of 300 degrees F.
Each A4VTG is built to order with options including custom shaft lengths and seals for higher temperatures and pressures. The A4VTG can be ordered with a variety of options including Rexroth’s C-series control valves, motorized valves and mechanical drive systems.

Rexorth A4VTG High Performance Hydraulic Pump
The Rexorth A4VTG Hydraulic Pump is designed for hydrostatic drives in open circuits and is particularly suitable for high power density applications.
The A4VTG is designed for hydrostatic drives in open circuits and is particularly suitable for high power density applications. The pump has a modular design with a separate hydraulic motor and hydraulic pump, making it ideal for custom applications. It is available with Rexroth’s patented Twin Disc technology, which allows the use of two pumps in series or parallel configurations.
Rexroth’s Twin Disc technology allows two pumps to be used in series or parallel configurations. The pump can be mounted directly on the motor shaft or remotely mounted on a shaft with an offset of up to 20 mm. The motors are available from 2 kW (3 HP) up to 16 kW (22 HP).
The integrated pressure control valve regulates the outlet pressure of the pump and feeds it back into the system through its own pressure sensor via an electronic control unit (ECU). The ECU regulates both speed and pressure according to changing requirements by means of three-stage control (speed/pressure/idling position).
It has a high power density of up to 0.85 kW/cm3, low noise emission, high efficiency, and no pumping loss.

This makes it ideal for use in vehicles such as heavy-duty trucks or buses with diesel engines up to 3 liters displacement per cylinder.
A4VTG pumps are available in five frame sizes with nominal pressures up to 350 bar and nominal displacements from 12.6 to 200 cm3/rev.
The A4VTG pump range is designed for high-performance applications in the industrial and automotive sectors, with features that include direct drive technology, 3D-printed parts, a ceramic shaft seal and a robust housing made of cast iron or aluminium.
Rexroth’s new A4VTG pump range incorporates its latest innovations in hydraulics technology to provide maximum efficiency and durability at low power consumption levels. The range includes five frame sizes (from 12.6 to 200 cm3) offering both low pressure and high pressure options from 60 bar up to 350 bar (6 MPa).
The control unit (contactor) accommodates any electrical and pneumatic control systems via the electrical interface plug connector (with the exception of A4VTG 132 & 180).
Rexroth hydraulic pumps are used for all types of hydraulic systems in the automotive, agricultural and industrial applications. The design of these pumps ensures high efficiency and reliability. Rexroth offers a broad range of hydraulic components to meet your specific needs. Rexroth Hydraulic Pumps are known for their durability, reliability and efficiency.
Rexroth A4VTG Series Hydraulic Pump is a compact, high-performance gear pump with an output power range from 0.2 to 360 kW (0.5 to 600 HP) at pressures up to 7 bar (100 psi). The control unit (contactor) accommodates any electrical and pneumatic control systems via the electrical interface plug connector (with the exception of A4VTG 132 & 180).
With the same operating mode and displacement, the performance of the Rexroth pump is 2-3% higher than that of other brands, which can save energy in actual use.
Rexroth hydraulic power units are used for hydraulic drive systems in construction machinery, mining vehicles, forestry machines and earthmoving equipment. They are also found in mobile machinery such as agricultural tractors, forklifts and buses. In addition, they are used in stationary installations such as cranes and lifts. The technology of hydraulic power units has been continually improved since its introduction into Germany in 1910. Today’s modern hydraulic power units have a high degree of standardization and long service life.

Rexorth A4VTG High Performance Hydraulic Pump
Rexorth A4VTG Pump rated pressure up to 350bar, not only can meet the general machine requirements, but also higher pressure environment requirements such as deck winch and petroleum drilling platform.
The Rexroth A4VTG Hydraulic Pump is an extremely compact, single-stage axial piston pump that delivers high flow rate and pressure. It is suitable for mobile applications with limited space. The A4VTG features a compact design, which includes a high-pressure seal housing combined with a low-pressure piston housing. This configuration reduces overall length and allows mounting directly on each other without additional brackets or supports. The A4VTG features modular construction for easy servicing and maintenance. The entire pump can be dismantled into three separate parts: the casing; the piston group; and the shaft assembly (including drive). Each individual part can be replaced separately if necessary through service openings in the casing, allowing for quick and easy access to all components.
All in all, the Rexorth A4VTG High Performance Hydraulic Pump boasts a great design and build quality and is an economical choice for those looking for a high performance product. The pump comes ready to use and only requires a good cleaning before you put it into operation.
