Rexroth Hydraulic Pump & Motor Guide

A4VG · A10VG · A7VO · A8VO · A10VO · A11VO · A2FE · A2FM · A6VE · A6VM

For overseas hydraulic equipment buyers, identifying the difference between a Rexroth variable pump and a hydraulic motor is the first step toward selecting the correct component.

This technical guide compares ten important Rexroth axial piston series, including closed-circuit pumps, open-circuit pumps, variable double pumps, fixed motors and variable plug-in motors.

Rexroth A4VG - High-Pressure Variable Pump

The Rexroth A4VG is an axial piston variable displacement pump for hydrostatic closed-circuit drives. The swashplate design allows flow and direction to be controlled according to the required machine operating condition.

Rexroth A10VG - Compact Variable Pump for Hydrostatic Drives

The A10VG axial piston variable pump is designed for closed-circuit hydrostatic transmissions. Its swashplate design provides continuously variable displacement and reversible flow direction through the neutral position.

The integrated boost pump supports charge and control oil supply. High-pressure relief valves protect the hydrostatic transmission, while different control options allow the pump to be adapted to different machine functions.

Rexroth A7VO - Bent-Axis Variable Pump

The Rexroth A7VO uses an axial tapered piston bent-axis design for open-circuit hydraulic systems. The pump is known for a broad range of control options and high power density for mobile and industrial applications.

Rexroth A8VO - Dual-Circuit Power for Mobile Machinery

The Rexroth A8VO is an axial piston variable double pump for open-circuit applications. It combines two variable bent-axis rotary groups in one compact assembly and is particularly valuable when a machine needs multiple hydraulic circuits.

Rexroth A10VO - Versatile Swashplate Variable Pump

The A10VO is a variable displacement axial piston pump in swashplate design for open-circuit hydrostatic drives. Pump flow changes with drive speed and displacement, providing flexible hydraulic power for mobile and industrial equipment.

Major advantages include broad control choices, compact installation, through-drive configurations and proven rotary group technology. The newer A10VO Series 60 also introduces eOC electronic control, lower pressure pulsation and increased power density for selected mobile-machine applications. :contentReference[oaicite:4]{index=4}

Rexroth A11VO - High-Performance Mobile Hydraulic Pump

The A11VO is a swashplate-type axial piston variable pump for open-circuit hydrostatic drives. It is designed for demanding mobile machinery where high hydraulic power, robust operation and flexible control are required.

From Hydraulic Flow to Mechanical Torque

Unlike the A4VG, A10VG, A7VO, A8VO, A10VO and A11VO pumps, the A2FE, A2FM, A6VE and A6VM are hydraulic motors. Their function is to convert hydraulic energy into rotary mechanical output.

Rexroth A2FE - Fixed Plug-In Bent-Axis Motor

The A2FE is a fixed displacement axial piston plug-in motor using bent-axis technology. Its compact plug-in architecture is intended for direct integration into mechanical gearboxes and mobile drive systems.

Depending on series and configuration, A2FE sizes extend from small displacement motors to large high-torque versions. For a B2B replacement order, the complete type code, displacement, shaft configuration, mounting and pressure rating should be checked.

Rexroth A2FM - High-Pressure Fixed Axial Piston Motor

The Rexroth A2FM is a fixed displacement bent-axis axial piston motor. It is designed for applications requiring stable displacement, high torque density and robust rotary power transmission.

Rexroth A6VE - Variable Plug-In Motor for Travel Drives

The A6VE is a variable plug-in axial piston motor with bent-axis design. Its recessed mounting flange allows the motor to integrate into mechanical gearboxes while maintaining a compact installation footprint.

The Series 63 A6VE is especially suited to mobile travel drives. The displacement can be varied toward zero, enabling a wide operating range from high-speed travel to high-torque operation. Bosch Rexroth documentation identifies applications such as crawler excavators and gearbox-integrated mobile drives. :contentReference[oaicite:5]{index=5}

Rexroth A6VM - High-Pressure Variable Motor

The A6VM is one of the best-known Rexroth variable displacement axial piston motors. Its bent-axis architecture and wide displacement control range allow hydraulic systems to balance speed and torque according to operating conditions.

Common Industries & Equipment

The right Rexroth hydraulic pump or motor depends on the machine architecture, hydraulic circuit, required pressure, flow, torque, speed and control method.

1. Which Rexroth series are pumps?

A4VG, A10VG, A7VO, A8VO, A10VO and A11VO are pump families. A8VO is specifically a variable double pump.

2. Which Rexroth series are motors?

A2FE, A2FM, A6VE and A6VM are motor families. A2FE is a fixed plug-in motor, A2FM is a fixed motor, while A6VE and A6VM are variable motors.

3. What is the difference between A4VG and A10VG?

Both are variable pumps for closed-circuit hydrostatic drives, but they belong to different product platforms and cover different nominal sizes, control options and performance ranges.

4. What is the difference between A7VO and A10VO?

Both are open-circuit variable pumps, but A7VO uses bent-axis technology while A10VO uses swashplate technology.

5. What is the main advantage of A8VO?

A8VO integrates two variable pump sections into one compact unit, making it useful for machines requiring multiple hydraulic circuits and high total flow.

6. Is A6VM a fixed or variable motor?

A6VM is a variable displacement axial piston motor. Its displacement can be adjusted to balance output speed and torque.

7. What is the difference between A2FM and A6VM?

A2FM is a fixed displacement motor, while A6VM is a variable displacement motor. A6VM offers a wider operating range for speed and torque control.

8. Can one Rexroth pump replace another series directly?

Not necessarily. Displacement alone is insufficient. Pressure, speed, shaft, mounting flange, ports, control system, rotation direction and hydraulic circuit must all be checked.

9. How should I select the correct displacement?

Start with required flow, pressure, engine or motor speed, hydraulic power and machine duty cycle. Then confirm the available nominal size and control configuration.

10. What information should an overseas buyer provide?

The best information is the complete nameplate code, displacement, machine model, application, operating pressure, speed, control type and clear photos of the existing unit.

Before You Order a Rexroth Pump or Motor

For international B2B procurement, the complete ordering code is more reliable than selecting a component by series name alone.

A Practical Rexroth Hydraulic Pump & Motor Reference for Global B2B Buyers

Rexroth's axial piston portfolio covers different hydraulic architectures: A4VG and A10VG are closed-circuit variable pumps; A7VO, A10VO and A11VO are open-circuit variable pumps; A8VO provides a variable double-pump solution; while A2FE, A2FM, A6VE and A6VM provide fixed, variable and plug-in motor solutions.

For overseas customers sourcing hydraulic pumps and hydraulic motors, the most important selection factors are not only the series and displacement, but also the complete model code, hydraulic circuit, rated pressure, maximum pressure, rotational speed, control type, mounting configuration, shaft, ports and actual machine application.
