Product Overview
▔▔
The Rexroth A10VSO18 is a high-precision, swashplate-design axial piston variable displacement pump specifically engineered for open-circuit industrial hydraulic systems. Operating within the industry-standard Rexroth A10VSO Series 31 / Series 52 platforms, this size-18 displacement pump integrates advanced pressure, flow, and power control functions. It is tailored for demanding precision control applications that require high power density, continuous operational reliability, dynamic response, and strict energy efficiency.
Key Advantages
▔▔
- High-Precision Swashplate Architecture: Delivers precise, stepless control over displacement and flow output, optimizing energy usage and minimizing system heat generation.
- Versatile Control Modes: Fully compatible with standard Rexroth pressure controls (DR), pressure and flow controls (DRG / DFR / DFR1), and power controls (LR3 / LA1) for flexible hydraulic circuit integration.
- Low Noise & Compact Footprint: Specially contoured stroke mechanism and port design lower acoustic emission levels while preserving a compact form factor for tight installation spaces.
- Robust Load Capability: Heavy-duty bearings and optimized tribological pairs enable high nominal pressure performance and long service life under heavy cyclic duty.

Applications
▔▔
- Plastic Injection Molding Machinery: Drives the core-pulling, clamping, and proportional flow/pressure holding circuits, ensuring stable part dimensions and low energy consumption during extended dwell times.
- Metal Stamping Presses & Bending Machines: Serves as the primary variable displacement fluid source for secondary holding cylinders and auxiliary clamping circuits requiring rapid, dynamic pressure compensation.
- Hydraulic Test Benches & Automation Equipment: Provides stable, ultra-low pulsation hydraulic flow and pressure regulation for precise actuator positioning and dynamic load testing.
- CNC Machine Tools & Workholding Fixtures: Controls automatic tool changers, chucking mechanisms, and work-piece clamping tables where precise force maintenance and small physical footprints are essential.

FAQ
▔▔
Q1: What does "Open Circuit" mean for this pump?
A: In an open circuit system, the pump draws hydraulic fluid from a reservoir tank and pumps it through the system to do work (like moving a cylinder). Afterward, the fluid flows all the way back into the tank before being drawn in again.
Q2: Can the A10VSO18 pump run in both clockwise and counter-clockwise directions?
A: No, these pumps are usually manufactured with a specific direction of rotation (either Right-hand "R" or Left-hand "L"). You must check the model code on the nameplate to ensure it matches your motor's rotation direction, as running it backward can destroy the pump.
