Rexroth A10VSO18 Pump | A10VSO18DFR, A10VSO18DFR1 | Axial Piston Variable Pump

Rexroth A10VSO18 Series High-Pressure Axial Piston Variable Pumps

Product Overview: The Rexroth A10VSO18 Series is one of the most reliable “hearts” for global industrial hydraulic systems. As a definitive swashplate design variable displacement pump, it is engineered specifically for open-circuit applications, maintaining exceptional stability under high-frequency operation. This selection features two elite control configurations: A10VSO18DFR/31R-VKC62N00 (Pressure & Flow Control) and ALA10VSO18DFR1/31L-VSC12N00 (Load-sensing with remote pressure control). Renowned for superior self-priming and low-noise characteristics, the A10VSO18 is the premier choice for machine tools, injection molding machines, small presses, hydraulic power units (HPU), and automated production lines.

Key Technical Advantages:

• Precision DFR/DFR1 Controls: Features Load-Sensing (DFR) and pressure cut-off mechanisms that match flow exactly to system demand, significantly reducing energy consumption and heat buildup.

• Superior Power-to-Weight Ratio: Delivers a nominal pressure of 280 Bar (4000 PSI) within a compact envelope, with peak pressures reaching 350 Bar.

• Excellent Noise Reduction: Optimized swashplate and valve plate architecture ensure exceptionally low noise levels even during full-load operation.

• Longevity & Durability: Equipped with high-quality bearing groups and supports through-drive capability, allowing for easy mounting of additional gear or piston pumps.

• High Flexibility: Supports multiple installation standards (e.g., VKC62 and VSC12 shaft configurations) for rapid integration with various motors and transmissions.

• Target Applications: Industrial pumping stations, plastic processing machinery, metal forming equipment, and hydraulic clamping systems.
