1, Product Overview
· Product Name: Rexroth A10VSO series axial piston variable displacement pump
· Product type: Slant disc, variable displacement, axial piston pump
· Core function: Convert mechanical energy (driven by motors or engines) into hydraulic energy (flow and pressure), and its output flow can be infinitely changed according to system requirements during operation.
· Main features:
· High performance: The maximum working pressure can reach 280 bar (approximately 4000 psi), with even higher peak pressures.
· High efficiency: The volumetric efficiency and mechanical efficiency are very high, and the energy-saving effect is significant, especially in variable systems.
· Low noise: The optimized design results in lower operating noise.
· Multiple control forms: Provides extremely rich variable control methods to meet any complex system requirements.
· Long lifespan and high reliability: The sturdy design and high-quality materials ensure an extremely long service life.

2, Working principle
The core principle of A10VSO pump is the reciprocating motion of the inclined plate principle:
1. Power input: The drive shaft drives the cylinder block to rotate through splines.
2. Piston movement: Multiple plungers (usually 7 or 9) arranged along the axial direction in the cylinder body, with their head sliding shoes pressed against the inclined plate. Due to the angle between the inclined plate and the axis, when the cylinder body rotates, the plunger undergoes reciprocating motion within the cylinder bore.
3. Oil suction and pressure: When the plunger moves outward, the volume increases and oil is sucked in through the oil suction window of the distribution plate; When the plunger moves inward, the volume decreases and the oil is squeezed out through the pressure window of the distribution plate.
4. Variable: The angle of the inclined plate determines the stroke of the plunger. The larger the angle, the longer the stroke, and the greater the pump's displacement (flow rate per revolution); When the angle is 0, the displacement is 0. By changing the angle of the inclined plate, the output flow can be infinitely adjusted during pump operation without changing the motor speed

3,Main application areas
A10VSO pumps are widely used in various industrial fields due to their excellent performance:
· Plastic machinery: injection molding machines (which are its most classic application areas), extruders.
· Press machines: metal forming hydraulic press, bending machine, shearing machine.
· Machine tools: machining centers, grinders, and combination machine tools.
· Construction machinery: Although not the main product, it is also used for some industrial walking machinery.
· Testing equipment: fatigue test bench, material testing machine.
· Metallurgical equipment: steel rolling auxiliary equipment, steelmaking equipment.
· Marine engineering: deck machinery, servo system.

4, Selection precautions
1. Determine displacement: Calculate based on the required flow rate of the system and the speed of the drive motor.
2. Choose control mode: This is the most crucial step, which needs to be determined based on the system's operating conditions, energy-saving requirements, and control complexity.
·Simple pressure holding/clamping: Choose DR control.
·Require high efficiency and energy saving: choose LR load sensing control.
·Need to be integrated into the automation control system: proportional control of power selection.
3. Confirm installation dimensions: flange standards (such as ISO 3019/2, SAE C) and shaft extension forms (such as 1:10 taper splines, flat keys) must be matched with the motor.
4. Check the oil port and options: The size, direction, and sealing material (NBR or FKM) of the oil port must meet the system requirements.
5. Oil cleanliness: must be ensured! Contaminated oil is the primary cause of damage to plunger pumps.
