Product Specifications

Key Features & Highlights

Elevating your machinery's capabilities requires components that go beyond basic functionality. The A10VNO series is engineered with a strict focus on structural integrity and operational finesse, ensuring that every rotation translates into tangible productivity gains for your heavy-duty equipment.

• Unrestricted Through-Drive Capability: Features a 100% through-drive design, allowing the seamless mounting of secondary gear pumps or identical axial piston units. This drastically reduces the installation footprint within tight engine compartments and simplifies multi-circuit mechanical configurations.

• Rapid Response Mechanisms: The internal control architecture is optimized for extremely short control times. This ensures the pump reacts instantly to pressure or flow commands, preventing system lag and enhancing overall machine agility during complex maneuvers.

• Heavy-Duty Bearing Assembly: Equipped with high-capacity bearings designed to absorb substantial axial and radial loads directly at the drive shaft. This eliminates the need for external support structures, simplifying the overall drivetrain design and reducing assembly time.

• Acoustic Optimization: The internal port plate and piston timing are engineered to minimize fluid pulsation. The result is a remarkably quiet operation that complies with stringent occupational noise regulations, creating a safer and more comfortable environment for operators.

• Versatile Control Spectrum: Fully compatible with a wide array of control valves, including DR, DFR, DRG, DRS, and advanced electro-hydraulic options (ED71, EP1D, etc.). This provides the exact modulation required for diverse application profiles without requiring a complete system redesign.

Frequently Asked Questions

To assist your engineering and procurement teams in making informed decisions, we have compiled detailed answers to the most common technical inquiries regarding our variable displacement pump series.

• Q: How does the through-drive capability benefit multi-circuit hydraulic systems?
  A: The 100% through-drive allows you to mount an additional pump directly to the rear of the primary unit. This creates a tandem configuration driven by a single power take-off (PTO), saving critical space and reducing the complexity and weight of the mechanical drive train.

• Q: Can this pump operate efficiently with environmentally friendly or synthetic hydraulic fluids?
  A: Yes, the robust internal metallurgy and advanced seal configurations are highly compatible with a wide range of hydraulic fluids, including standard mineral oils and many synthetic or biodegradable alternatives, provided they meet the required viscosity and cleanliness standards.

• Q: What is the recommended fluid cleanliness level to ensure the maximum lifespan of the internal bearings?
  A: To maintain the integrity of the precision-machined swashplate and heavy-duty bearings, we recommend maintaining a fluid cleanliness level of at least 20/18/15 according to ISO 4406. Proper filtration is critical for maximizing the operational lifecycle and preventing premature wear.

• Q: How does the DFR (pressure and flow control) valve optimize energy consumption in mobile machinery?
  A: The DFR control actively adjusts the pump's displacement to match the exact flow and pressure demanded by the actuators. By only generating the hydraulic power that is currently needed, it eliminates the energy waste associated with dumping excess fluid over a relief valve, significantly reducing fuel consumption and heat generation.

• Q: What are the specific advantages of using this series for engine cooling fan drives?
  A: In fan drive applications, the pump's rapid response time and stepless variable displacement allow the cooling fan speed to be precisely modulated based on the engine's real-time thermal load. This precise control reduces parasitic engine losses, lowers noise emissions, and prevents the engine from overcooling.
