Rexroth A8VO107 axial piston double hydraulic pump

The Rexroth A8VO107 distinguishes itself through a masterfully executed axial piston, variable displacement design. This foundational architecture transcends simple fluid movement, evolving into a philosophy of on-demand power efficiency. Mastering this principle is not merely academic—it is essential for unlocking the pump's full potential in optimizing system performance, reducing total cost of ownership, and achieving operational excellence.

The Swashplate Mechanism: Intelligence in Motion

At the operational core of the A8VO107 lies its defining component: the variable-angle swashplate. This ingenious mechanism is the key to its adaptability. Here’s how it transforms input power into intelligent output:

Kinematic Precision:​ Multiple pistons are arranged axially around a central drive shaft. As the shaft rotates, these pistons reciprocate within their cylinder bores, their stroke length dictated by the angle of the inclined swashplate they contact.
The Angle of Efficiency:​ The swashplate's angle is not fixed; it is dynamically adjustable. A steeper angle creates a longer piston stroke, resulting in higher volumetric displacement and greater flow output. Conversely, a reduced angle shortens the stroke, decreasing displacement and flow.
The Ultimate Benefit:​ This real-time adjustability allows the A8VO107 to act as a "just-in-time" power source, delivering precisely the hydraulic flow demanded by the system at any given moment. This eliminates the wasteful constant flow and bypass heating endemic to fixed-displacement systems, culminating in dramatic energy savings.
Control Versatility: A Pump Tailored to Your Application

The A8VO107’s intelligence is expressed through its suite of integrated control options. These controls automate the swashplate’s response, making the pump a responsive partner in your hydraulic circuit.

Pressure Control (LR, LRDS):​ The efficiency standard. In standby, the pump operates at minimal displacement (near-zero flow). It only increases output to build or maintain a pre-set system pressure. This "standby at low pressure" mode​ slashes energy consumption and heat generation during clamping, positioning, or holding cycles, making it ideal for presses and machine tools.
Flow Control (LU, LUE):​ For processes demanding consistency. This control maintains a nearly constant output flow rate independent of pressure variations (within operational limits). It is essential for applications like conveyor drives, mixers, or feed systems​ where a steady actuator speed is critical to process quality.
Power Control (LRG, LRD):​ The guardian of the prime mover. This control limits the product of pressure and flow (horsepower) to a preset maximum. It protects diesel engines or electric motors from stalling or overload, a non-negotiable feature in mobile equipment like excavators and loaders where engine power is a finite resource.
Industry-Proven Applications: Powering Critical Machinery

The Rexroth A8VO107 is the trusted hydraulic heart in sectors where performance is non-negotiable.

Mobile & Off-Highway Equipment:​ The dominant force in construction and agriculture. It delivers the intelligent, high-power flow required for the main hydraulic systems of excavators, wheel loaders, telescopic cranes, and drilling rigs, with power control protecting the diesel engine.
Industrial Manufacturing & Automation:​ A cornerstone of precision production. It drives plastic injection molding machines, provides consistent force for metal stamping presses, and powers high-cycle test benches, where its repeatable control ensures product quality and process reliability.
Forestry & Heavy Material Handling:​ Built for shock loads. It operates reliably in harvesters, forwarders, and port-side container handlers, where sudden load changes and particulate contamination are routine, demanding unwavering robustness.

Specifications

Selection Table

Q1: How does the "double pump" (DA) configuration work?

A1: The A8VO can be specified as a double pump (DA), where a second pump unit (often a gear pump) is flange-mounted to the main A8VO107. This creates a compact, dual-flow source from a single input shaft—perfect for powering separate circuits, such as a main implement circuit and a pilot/steering circuit, from one engine or motor.

Q2:Can the control parameters be adjusted in the field?

A2:Yes, for mechanical-hydraulic controls (like pressure or power control), adjustment screws with locknuts are provided for setting pressure limits, flow, or power curves. Adjustments should only be made by qualified personnel​ with the correct pressure gauges and system knowledge, as incorrect settings can lead to system damage or hazardous operation.
