Rexroth A8VO: The Robust Hydraulic Core for Demanding Axial Drive Systems

In the realms of heavy construction, foundation engineering, and material handling, axial drive systems—powering everything from drilling rotors to conveyor drives—face relentless demands. These systems require a hydraulic pump that delivers not only immense power but also exceptional control and resilience under continuous high load. The Rexroth A8VO series axial piston variable pump is engineered to meet this challenge, serving as a reliable Axial Main Pump for premier equipment manufacturers like New Holland and Casagrande.

Engineered for Extreme-Duty Performance
The A8VO pump is synonymous with durability, backed by a one-year warranty. Its design is focused on superior resistance to extreme pressure shocks, abrasive contamination, and thermal stress. This makes it ideal for the punishing conditions of piling rigs, tunnel boring, and round-the-clock material processing. Its robust construction ensures reliable operation where it matters most, directly contributing to the uptime of critical machinery.

Versatile Power for a Multitude of Applications
The intelligence and strength of the A8VO hydraulic pump make it a cornerstone component across diverse sectors and leading OEMs.

Foundation & Drilling Rigs: In Casagrande piling rigs and Soilmec foundation equipment, the pump provides the high-torque, controlled power essential for drilling and casing operations. Its performance is critical for models like the XG450D and XG360D, ensuring consistent force in variable soil conditions.

Agriculture & Material Handling: For New Holland large harvesters and Sennebogen material handlers, the pump’s efficiency and durability support high-cycle tasks. It reliably powers systems in machines often serviced under part numbers like 6559073 and 385313.

Mining & Specialized Transport: The pump meets the demands of Terex mining trucks and TMLTechnik GmbH specialized trailers. Its ability to handle 400 bar pressure is crucial for these heavy-duty applications. Components such as 92201050 and Uds114r are integral to these systems.

Cross-Industry Reliability: The pump’s widespread use is confirmed by its presence in global parts networks under various codes, including 599305780 and 50760128, facilitating maintenance for equipment from ENMTP and other manufacturers.

Frequently Asked Questions (FAQ)

Q1: What makes the A8VO series particularly suitable as an axial main pump for drilling rigs?
A1: Its combination of high continuous pressure rating (400 bar), large displacement range, and precise flow control allows it to deliver the constant, high torque needed for rotary drives, even under the shock loads encountered when drilling through rock or hard strata.

Q2: How does the pump’s design protect it in harsh, dusty environments?
A2: The A8VO features a robust design with effective sealing systems to prevent contaminant ingress. Its hardened internal components are built to resist wear from abrasive particles common in mining, quarrying, and demolition sites.

Q3: Can this pump be used in both open and closed-circuit systems?
A3: The A8VO series is primarily designed for open-circuit applications. Its variable displacement and pressure control make it highly efficient for the load-sensing systems typically found in the mobile machinery of the brands listed.

Q4: We need a replacement pump for our equipment. How do we ensure compatibility?
A4: For a guaranteed fit, always reference your machine’s original part number. You can access detailed technical documentation and confirm compatibility by visiting www.baolilai-pump.com/contact_us/ to consult with our engineering team.
