The flagship model A11VLO130DR/10L-NZD12N00 (Part No.: R902007906) embodies the series’ core advantages, while variants like A11VLO130DRS and A11VLO130 cater to diverse hydraulic system requirements. Designed for high-pressure, continuous-load scenarios, this pump delivers reliable power for heavy machinery, making it a trusted choice for industrial operators worldwide. Below is a comprehensive breakdown of its core value, model decoding, performance strengths, application scenarios, and series compatibility.
-
The A11VLO130 Series belongs to the renowned A11VLO product family, specialized as an axial piston variable displacement pump for closed and open hydraulic circuits (with flexible adaptation to both setups). Its core positioning focuses on "heavy-duty industrial applications requiring stable high pressure and precise flow control"—serving as the "energy backbone" for equipment that demands consistent performance under extreme loads, frequent start-stops, and harsh environmental conditions.
-
At the heart of its design is the integrated DR regulator—a precision control module that enables dynamic pressure and flow adjustment, ensuring the pump adapts seamlessly to real-time load changes. The model A11VLO130DR/10L-NZD12N00, paired with the exclusive part number R902007906, is engineered for direct replacement and rapid integration, minimizing equipment downtime and maintenance costs for industries relying on continuous operation.
-
Every segment of the A11VLO130 Series model code conveys precise technical information, ensuring compatibility with specific system requirements. Here’s a detailed breakdown of the target model:
-
-
Equipped with a factory-calibrated DR regulator, the pump supports automatic pressure-compensated flow control—adjusting output flow from 0 to 100% based on real-time system demands. This eliminates energy waste from constant-flow operation, reducing operational costs while preventing system overload. The DR regulator’s response time of less than 45ms ensures rapid adaptation to sudden load changes, making it ideal for applications requiring stable force and speed control (e.g., mining equipment, construction machinery).
-
Built with a reinforced cylinder block, high-strength alloy pistons, and a hardened valve plate, the pump withstands long-term high-pressure operation (maximum system pressure up to 35 MPa for intermittent use). Its volumetric efficiency exceeds 94%, minimizing internal leakage and ensuring consistent flow output even under continuous heavy loads. The optimized oil distribution design reduces pressure pulsation, enhancing overall system stability and extending the lifespan of downstream components.
-
The pump features a modular, heavy-duty design—key components (piston, swashplate, DR regulator) are crafted from wear-resistant materials (e.g., chrome-plated steel, ceramic coatings) to resist corrosion, abrasion, and extreme temperatures. The sealed housing (IP65-rated) protects internal parts from dust, moisture, and contaminants, making it suitable for harsh industrial environments (mines, construction sites, forging plants). Under normal operating conditions, the mean time between failures (MTBF) exceeds 7,800 hours, ensuring minimal maintenance and downtime.
-
Compatible with a range of hydraulic oils (mineral oil, synthetic oil, fire-resistant hydraulic fluid) and operating temperatures (-25°C to 90°C), the pump adapts to diverse industrial scenarios. Its mounting flange and shaft end design comply with ISO 3019/2 standards, enabling direct replacement of legacy A11VLO130 pumps (e.g., A11VLO130DRS, A11VLO130) without modifying the original equipment structure. The DR regulator is also easily adjustable and replaceable, simplifying on-site maintenance.
-
The A11VLO130DR/10L-NZD12N00 (Part No.: R902007906) and its A11VLO130 Series variants are widely utilized in high-demand hydraulic systems across industries:
Construction & Mining: Hydraulic excavators, bulldozers, crushers, drilling rigs, and conveyor systems.
Manufacturing & Forging: Hydraulic presses, forging machines, rolling mills, and die-casting equipment.
Agricultural & Forestry: Large-scale harvesters, tractors, and forestry machinery (e.g., log loaders).
Marine & Offshore: Ship deck machinery, offshore platform hydraulic systems, and port cranes.
Industrial Automation: Heavy-duty automated production lines, custom high-pressure hydraulic stations, and material handling equipment.
-
The A11VLO130 Series offers flexible variants to meet specialized control and performance needs, with core components interchangeable for unified maintenance:
A11VLO130: Basic variant without the DR regulator, designed for cost-sensitive applications requiring manual flow control (e.g., simple hydraulic systems).
A11VLO130DR: The target model’s core variant, featuring the DR pressure-compensated regulator for precision load matching (ideal for most heavy-duty stationary and mobile equipment).
A11VLO130DRS: Enhanced variant with a servo-controlled DR regulator (S), supporting electronic proportional control for Industry 4.0-integrated systems (e.g., smart manufacturing lines).
-
All variants meet international quality certifications (ISO 9001, CE) and adhere to strict industrial standards, ensuring consistent performance and compatibility across the series.
