The Rexroth A8VO: A High-Performance Heart for Doosan Excavators
The reliability and efficiency of a modern excavator hydraulic system are paramount, directly impacting power, control, and uptime. For demanding Doosan excavator models, the Rexroth A8VO series hydraulic piston pump serves as a robust and intelligent power source, engineered to meet the rigorous demands of cyclical digging and material handling. This variable displacement axial piston pump, renowned for its high efficiency and superior stability, is the ideal direct replacement or compatible solution for your Doosan machinery’s hydraulic system.
Technical Specifications and Robust Design
The A8VO series hydraulic pump is designed for high-pressure performance in open-circuit systems common to excavators. Below are its core technical parameters:
| Parameter | Value Range |
|---|---|
| Displacement (Max.) | 55 – 200 cm³/rev |
| Operating Pressure | 350 – 400 bar |
| Maximum Speed | 1950 – 3000 rpm |
Built with hardened components and precision engineering, the A8VO pump offers exceptional resistance to pressure shocks, extreme environmental conditions, and abrasive contamination. The “bent-axis design with two axial tapered piston rotary assemblies” contributes to its high volumetric efficiency and operational stability under fluctuating loads. It comes with a comprehensive one-year warranty, ensuring reliable performance and peace of mind.
Application Across Doosan’s Diverse Equipment Portfolio
The A8VO pump’s versatility makes it a key component across the Doosan (doosan.com) product range, which spans multiple demanding industries.
Construction & Earthmoving: As the primary hydraulic pump in Doosan excavators, it provides the high-torque, controlled power necessary for the S340-V model (part 401-00254B), the DX420, and other heavy-duty digging cycles.
Mining & Quarrying: In larger Doosan models like the DX520LC excavator, the pump’s ability to sustain high pressure (up to 400 bar) is critical for tough rock-breaking and continuous material handling operations.
Material Handling & Specialized Tasks: The pump’s precise flow control supports the smooth operation of auxiliary functions in various Doosan loaders and specialized equipment, ensuring efficiency in tasks from lifting to precise grading.
The pump’s widespread use is confirmed by its integration across numerous Doosan machine models, with components cross-referenced under codes like 400914-00247, K1000288B, K1003280B, 400914-00230, 401-00476A, and 401-00369.
Frequently Asked Questions (FAQ)
Q1: Is this A8VO pump a direct replacement for the original pump in my Doosan excavator?
A1: Yes. When the correct displacement model (e.g., A8VO80,A8VO140, A8VO200) and control configuration matching your machine’s original specifications (like K1000288B) are selected, it is engineered for 100% interchangeability with the original Rexroth A8VO series design.
Q2: How does the variable displacement feature benefit my excavator’s operation?
A2: Unlike fixed pumps, a variable displacement pump like the A8VO automatically adjusts its output flow to match the system’s real-time demand. This leads to significant energy savings, reduced heat generation, smoother machine control, and improved overall fuel efficiency.
Q3: What makes this pump suitable for harsh mining or demolition sites?
A3: The A8VO’s robust construction features advanced sealing systems to prevent dust and moisture ingress. Its hardened internal components are specifically designed to withstand the abrasive wear and severe pressure shocks common in these environments.
Q4: Where can I find the detailed technical specifications and installation drawings?
