Product Description

Product Description: A4VSO40 Series Axial Piston Variable Pump (Model: AA4VSO40LR2G/10R-PPB13N00 | Part No.: R910905023)

As a compact yet high-performance workhorse in industrial hydraulic systems, the A4VSO40 Series Axial Piston Variable Pump stands out for its precision control, space-saving design, and reliable operation across light-to-medium load scenarios. The flagship model AA4VSO40LR2G/10R-PPB13N00 (Part No.: R910905023) embodies the series’ core advantages, while its diverse variants—including A4VSO40DR, A4VSO40DRG, and AA4VSO40LR2—cater to customized hydraulic system demands. Below is a comprehensive breakdown of its core value, model decoding, performance strengths, application scenarios, and series compatibility.

I. Core Positioning: Compact Power Core for Precision Hydraulic Systems

The A4VSO40 Series belongs to the iconic A4VSO product family, specialized as an axial piston variable displacement pump for open hydraulic circuits. Designed with a compact footprint, it serves as the "precision energy hub" for small-to-medium industrial equipment, efficiently converting mechanical energy into stable hydraulic pressure to drive actuators with exceptional accuracy. Its core positioning focuses on "high performance in limited space"—balancing power, efficiency, and maneuverability to meet the needs of equipment requiring precise flow control without compromising on durability.

The model AA4VSO40LR2G/10R-PPB13N00, paired with the exclusive part number R910905023, is engineered for seamless integration and rapid replacement. It minimizes downtime for maintenance and equipment upgrades, making it a cost-effective choice for industrial operators and equipment manufacturers.

II. Full Model Interpretation: Decoding Technical Specifications

Every segment of the A4VSO40 Series model code conveys precise technical information, ensuring compatibility with specific system requirements. Here’s a detailed breakdown of the target model:

Code Segment	Core Meaning
AA4VSO	Product Series Identifier: Premium upgraded variant of the classic A4VSO line, featuring enhanced structural integrity, advanced control technology, and improved wear resistance.
40	Displacement Specification: Nominal displacement of 40 cm³/rev, optimized for compact hydraulic systems requiring efficient flow output without excessive energy consumption.
LR2G	Control & Structural Code: "LR" indicates linear-response swashplate control for smooth, precise flow regulation; "2" denotes the second-generation design with reduced internal friction; "G" signifies a reinforced gear mechanism for enhanced torque transmission and stability.
/10R	Pressure Rating & Rotation Direction: "10" refers to a maximum rated pressure of 10 MPa (1450 psi), tailored for light-to-medium pressure working conditions; "R" denotes clockwise rotation (viewed from the shaft end), aligning with standard industrial drive configurations.
-PPB13N00	Control Valve & Interface Configuration: "PPB" stands for a proportional pressure control valve with built-in feedback, enabling electronic or manual precision adjustment of system pressure; "13N00" denotes standard hydraulic interface size and neutral position settings, ensuring compatibility with most industrial control systems and easy integration.

III. Core Performance Advantages: Engineered for Precision & Reliability

1. Compact Design & Space Efficiency

With a streamlined, space-saving structure, the pump fits seamlessly into tight equipment layouts—ideal for small industrial machinery, mobile hydraulic systems, and custom hydraulic stations where installation space is limited. Despite its compact size, it delivers consistent flow output and pressure stability, outperforming conventional pumps in power-to-size ratio.

2. Precision Variable Control & Energy Savings

Equipped with the PPB13N00 proportional control valve, the pump supports stepless flow regulation (0-100%) that dynamically adapts to the equipment’s real-time load demand. This eliminates energy waste from constant-flow operation, reducing operational costs. The control system’s response time of less than 35ms ensures rapid adaptation to load fluctuations, making it perfect for applications requiring precise speed and force control (e.g., small hydraulic presses, automated assembly lines).

3. Durable Construction & Low Maintenance

Crafted with high-strength alloy materials for key components (piston, cylinder block, valve plate), the pump exhibits excellent wear resistance and corrosion protection. Its modular design allows for easy disassembly and component replacement, with key parts interchangeable across the A4VSO40 Series. The enhanced sealing structure (compliant with IP64 standards) prevents leakage and dust ingress, while the integrated thermal management system avoids overheating. Under normal operating conditions, the mean time between failures (MTBF) exceeds 8,000 hours, ensuring long-term reliability and minimal maintenance costs.

4. Wide Adaptability & Seamless Integration

Compatible with a range of hydraulic oils (mineral oil, synthetic oil, biodegradable oil) and operating temperatures (-20°C to 80°C), the pump performs reliably in diverse industrial environments (high humidity, dust, mild vibration). Its mounting flange and shaft end design comply with ISO 3019/2 standards, enabling direct replacement of legacy pumps (e.g., A4VSO40DR, A4VSO40FR) without modifying the original equipment structure.

IV. Application Scenarios: Tailored for Light-to-Medium Load Industries

The AA4VSO40LR2G/10R-PPB13N00 (Part No.: R910905023) and its A4VSO40 Series variants are widely utilized in precision hydraulic systems across industries:

Industrial Automation: Automated assembly lines, small hydraulic presses, robotic arms, and precision machining equipment.
Mobile Hydraulics: Small excavators, mini loaders, agricultural machinery (e.g., compact harvesters), and utility vehicles.
Light Manufacturing: Packaging machinery, printing presses, textile equipment, and food processing machinery.
Custom Hydraulic Systems: Compact hydraulic stations, laboratory test equipment, and specialized industrial tools.
Automotive & Aerospace: Hydraulic control systems for vehicle assembly lines and aircraft maintenance equipment.

V. Series Compatibility & Related Variants

The A4VSO40 Series offers diverse variants to meet customized control and performance needs, with core components interchangeable for unified maintenance:

A4VSO40DR: Direct-acting control variant, featuring a simplified control mechanism for cost-sensitive, basic hydraulic systems (e.g., small lifts, manual hydraulic tools).
A4VSO40DRG: Direct-acting control variant with reinforced gear (G) for enhanced torque and stability, suitable for light-load mobile equipment.
AA4VSO40LR2: Linear-response control variant (without the G gear reinforcement), ideal for precision stationary systems like automated assembly lines.
A4VSO40DFR/FR: Dual-flow and single-flow control variants, optimized for systems requiring adjustable flow rates for multiple actuators.
A4VSO40E02/E01: Electronic control variants with advanced digital interfaces, enabling integration with PLC systems for smart hydraulic control (ideal for Industry 4.0 applications).

All variants meet international quality certifications (ISO 9001, CE) and adhere to strict industrial standards, ensuring consistent performance and compatibility across the series.
