Product Description
Rexroth A4VSO Series Heavy-Duty Axial Piston Variable Pump
Product Overview: The Rexroth A4VSO series is an axial piston variable pump engineered specifically for extreme heavy-duty industrial applications, such as large metal forming presses, forging equipment, marine hydraulics, and massive hydraulic power units. With its powerful 250cc and 500cc displacement specs, the A4VSO series delivers exceptional stability under continuous high pressures of up to 350 Bar. By integrating advanced HS/HS4 hydraulic servo control systems, it achieves ultra-high dynamic response and precision position control.
Key Technical Advantages:
HS/HS4 Precision Servo Control: Models like the A4VSO250HS4/30R-VPB25UB4 and A4VSO500HS/30R-PPH25N00 utilize high-performance servo control logic. This technology allows for millisecond-fast displacement modulation via pilot pressure, making it the ideal power source for automated heavy extrusion lines.
Rugged Construction & Longevity: Designed for 350 Bar rated pressure and 400 Bar peak cycles. It features reinforced swashplate bearings and massive pump housings to ensure minimal failure rates during 24/7 continuous high-load operations.
Quiet Operation Performance: Despite its immense displacement, the A4VSO series maintains competitive low-noise levels through optimized port plate designs and acoustically reinforced pump casings—ideal for indoor industrial environments.
Versatile Thru-Drive Capability: High-displacement models like the A4VSO500 support 100% thru-torque transfer, allowing for tandem mounting of secondary or tertiary pumps to build compact, multi-circuit heavy-duty power units.
Specific Models & Technical Parameters: This product line features core configurations: A4VSO250HS4/30R-VPB25UB4, A4VSO250HS/30R-PPB25N00, and A4VSO500HS/30R-PPH25N00. Key specifications: Displacements from 250 cm³/rev up to 500 cm³/rev; rated operating pressure of 350 Bar (35 MPa); peak pressure of 400 Bar; Clockwise (R) rotation; and standard ISO mounting flanges with various shaft options (e.g., VPB25 or PPH25).
