Each unit undergoes stringent endurance testing to ensure long life under heavy hydraulic loads. BAOLILAI’s one-year warranty underscores confidence in durability and reliability across extreme operating environments. Structural Advantages and Engineering Highlights The AA20VLO series incorporates advanced metallurgy and precision machining for high pressure tolerance (up to 400 bar). The pump casing is built from high-grade alloy steel with surface hardening to withstand shock loads and resist fatigue cracking. Key design advantages include: Explosion-resistant construction suitable for hazardous zones and mining sites. Temperature and corrosion resistance for offshore, desert, or cold-climate operations. High torque output and smooth control response for applications needing precise flow regulation. Energy efficiency through optimized swashplate geometry, reducing energy losses under part-load conditions. Application Across Global Machinery Platforms The Rexroth AA20VLO axial variable piston pump is widely integrated into the hydraulic systems of world-renowned machinery brands: Construction Equipment: Utilized in the Caterpillar 336 excavator and Volvo EC950E crawler excavator ( www.volvoce.com ), delivering consistent swing and travel circuit pressure. Agricultural Machinery: Powers the hydraulic drive on John Deere 8R Series tractors ( www.deere.com ) and CLAAS LEXION combines ( www.claas.com ), ensuring stable steering and lift control. Mining Equipment: Deployed in Komatsu HD785 dump trucks ( www.komatsu.com ) and Liebherr R9800 mining shovels ( www.liebherr.com ) where high torque and heat resistance are critical. Engineering and Road Machinery: Applied in Hitachi ZX470LCH excavators and Doosan DL550 wheel loaders , providing stable hydraulic power for steering and lifting circuits. Each of these systems relies on precise pressure modulation and flow control, areas where the AA20VLO series excels due to its quick response servo control and wide displacement range. Reliability in Harsh Environments The AA20VLO series is engineered for resilience under extreme conditions. With explosion-proof sealing, reinforced bearings, and corrosion-resistant coatings, the pump operates reliably in mining dust, marine salt, and desert heat. BAOLILAI’s production process ensures dimensional consistency, low internal leakage, and quiet operation even under full load at 3200 rpm. Regular maintenance and the use of ISO 4406-standard hydraulic oil filtration can further extend the service life of these pumps beyond 10,000 operating hours. Integration Recommendations Fluid Cleanliness: Maintain contamination levels below ISO 18/15/13 to preserve piston surface integrity. Cooling System: Employ oil coolers for sustained high-power applications to control viscosity and temperature. System Design: Match pump displacement to actuator speed demands, selecting between AA20VLO190, 260, or 280 for optimal flow. Mounting: Ensure proper alignment with the prime mover shaft to avoid bearing load imbalance. FAQ Q1: What is the main difference between the AA20VLO190, AA20VLO260, and AA20VLO280 pumps? A1: The difference lies in displacement and flow capacity. The AA20VLO280 pump provides higher flow at the same rpm, making it suitable for large excavators or mining shovels. Q2: Can the AA20VLO pump work in a closed-loop hydrostatic system? A2: Yes. With proper charge pumps and pressure relief valves, it integrates efficiently in closed-loop traction or swing drives. Q3: Is the pump explosion-proof? A3: Yes. BAOLILAI offers explosion-resistant housings and seals for environments like underground mining and offshore drilling. Q4: How long is the product warranty? A4: Each AA20VLO series pump includes a one-year warranty covering manufacturing defects and performance consistency. Q5: Where can I access technical drawings and performance curves? A5: Visit www.baolilai-pump.com or contact our technical department at www.baolilai-pump.com/contact_us/ for complete specifications. Conclusion With proven design efficiency, strong pressure capability (250–400 bar), and adaptability across industries, the Rexroth AA20VLO axial variable piston pump series—covering the AA20VLO190 , AA20VLO260 , and AA20VLO280 models—represents an ideal solution for modern hydraulic systems. From construction to agriculture, these pumps deliver reliability, safety, and performance in the toughest global work environments—backed by BAOLILAI’s one-year warranty and full after-sales technical support.
