description

The A8VO200 heavy-duty double variable pump adopts an industrial super-reinforced integral casting structure and dual swash plate independent variable control system, realizing synchronous or independent variable adjustment of double oil circuits. Optimized strictly for heavy-load impact, high-temperature continuous operation and complex variable load working conditions of large machinery, the pump achieves a rated working pressure of 315bar and a peak pressure up to 350bar, with far stronger pressure resistance and impact resistance than conventional medium and small displacement pumps. The core components adopt thickened high-strength wear-resistant alloy cylinder block, oversized precision piston assembly and imported nano-lapped valve plate, matched with gap self-compensation and anti-wear lubrication optimization technology, ensuring volumetric efficiency ≥97% under full-load heavy-duty operation and long-term non-attenuation performance. Equipped with a dual independent load-sensing variable mechanism, it can dynamically respond to the load changes of double hydraulic circuits, realizing accurate power distribution and stepless stable speed regulation, effectively avoiding power waste and action jitter during compound operation.

advantages

  • 200ml/r Ultra-Large Single-Side Displacement, Full Heavy-Load Power Surplus: The ultra-large 200ml/r single-side displacement design fills the gap of high-power hydraulic pumps for heavy machinery. Compared with medium and small displacement pumps, it has explosive flow and pressure reserve, completely solving the power shortage and construction efficiency bottleneck of large equipment in rock breaking, deep excavation and climbing working conditions.
  • Dual Independent Variable Control, Precise Power Distribution: Dual swash plate independent load-sensing variable system realizes separate regulation of double oil circuits. It intelligently distributes power according to different load demands of walking and working devices, avoiding power waste and ensuring smooth and coordinated compound actions of equipment.
  • Forced Circulation Heat Dissipation, Zero High-Temperature Attenuation: Equipped with exclusive large-flow forced circulation heat dissipation structure for heavy loads, which actively takes away internal heat generated by full-load operation. It effectively avoids high-temperature speed reduction, power attenuation and oil aging failures during long-hour continuous construction, ensuring stable power output all day long.
  • Ultra-High Full-Load Efficiency, Energy-Saving & Efficient: Precision alloy friction pair matching and low-loss large-flow oil circuit design ensure ultra-high full-load operating efficiency. While ensuring strong power, it reduces invalid power loss, achieving better energy-saving performance than ordinary large-displacement pumps under long-term heavy-load operation.
  • Integral Heavy-Duty Structure, Low Maintenance Cost: The ultra-rigid integral casting pump body is resistant to vibration, deformation and fatigue damage under severe working conditions. Standard OEM universal installation realizes plug-and-play replacement, shortening equipment overhaul cycle and reducing long-term maintenance and operating costs of heavy machinery.

FAQ

  • Q1: What equipment and working conditions is the A8VO200 suitable for?
  • A: The A8VO200 large-displacement heavy-duty double variable pump is specially used for 20–36 ton large construction machinery, including large excavators, rotary drilling rigs and heavy crawler equipment. It is applicable to severe working conditions such as rock breaking, deep excavation, long-term full-load operation and high-frequency compound construction.
  • Q2: What is the difference between A8VO200 and A4VG/A10VSO series pumps?
  • A: A4VG is medium and small displacement closed-circuit pump for light and medium machinery walking; A10VSO is open-circuit variable pump for industrial and light machinery; A8VO200 is a super-large displacement dual closed-circuit heavy-duty pump, exclusively for full-load high-power operation of large heavy machinery, with completely different power level and application positioning.
  • Q3: What is the advantage of dual independent variable structure?
  • A: The dual independent variable system can adjust the flow and pressure of the two hydraulic circuits separately, realizing intelligent power distribution. It ensures independent and stable operation of walking and working circuits, avoiding mutual interference and greatly improving equipment compound operation efficiency and stability.
  • Q4: When does the heavy equipment need to replace the A8VO200 pump?
  • A: If large equipment has insufficient rock-breaking power, obvious high-temperature power drop after long-hour operation, unstable compound action, slow response and increased fuel consumption, the original pump has aging performance and insufficient heavy-load capacity. Replacing with A8VO200 can restore full heavy-load power and high-efficiency operation.
  • Q5: What are the core maintenance points for A8VO200?
  • A: Use heavy-duty high-pressure anti-wear hydraulic oil for large machinery, strictly replace high-precision filter elements regularly to avoid particle wear; avoid long-term extreme overload operation; regularly check the heat dissipation system and dual-circuit variable valve group to prevent high-temperature aging and internal leakage, ensuring long-term stable full-load output.
