Rexroth A10VSO & A10VO Series Variable Displacement Piston Pumps

Product Overview: The Rexroth A10V series is one of the most widely utilized variable displacement piston pumps globally. This lineup encompasses the A10VSO (Series 31) for industrial stationary applications and the A10VO (Series 52) for mobile machinery. Core models include the compact 18cc (A10VSO18), 28cc (A10VO28), and the mid-range 45cc (A10VO45). Utilizing a classic swashplate design, these pumps provide seamless, stepless flow regulation. Equipped with DR (Pressure Control), the pump automatically reduces displacement upon reaching the preset pressure, significantly lowering energy consumption and preventing system overheating. It is the premier choice for machine tool power units, hydraulic balers, small crane travel drives, and agricultural equipment.

Key Technical Advantages:

• Superior Control Flexibility: Featuring DR (Pressure Control) and VPC (with Pressure Cut-off), these pumps maintain preset system pressures with extreme precision and rapid response times.

• Low-Noise Engineering: Optimized 9-piston rotating groups drastically minimize pressure ripples during operation, making them ideal for indoor industrial environments with strict noise regulations.

• High Power-to-Weight Ratio: Built with high-strength cast iron, these pumps maintain an impressive 280 Bar rating within a compact frame, facilitating easy installation in tight spaces.

• Extended Service Life: Internal bearings and valve plates undergo specialized surface hardening, compatible with diverse mineral and eco-friendly hydraulic fluids, ensuring service intervals exceeding 8,000 hours.

• Standardized Mounting: SAE-compliant flanges and shaft specifications support versatile through-drive options, allowing for easy configuration of tandem or triple pump setups.
