Rexroth A2F Series Hydraulic Pump | A2F016 A2F023 Axial Piston Pump Replacement

Genlu Hydraulic proudly introduces our A2F Series (covering 016, 023, 032 displacements) high-performance axial piston pumps. This series is engineered as a seamless, high-value replacement for the classic Rexroth A2F series of fixed-displacement axial piston pumps. Designed for applications requiring high output power, extreme shock-load resilience, and robust performance in both open and closed-loop hydraulic circuits, the A2F series is an industry staple for industrial drives and mobile machinery. Genlu guarantees 100% Drop-in Interchangeability in ISO mounting flanges, shaft profiles, and port geometries compared to original Rexroth units. Each A2F pump is validated through 100% simulation testing to ensure optimal volumetric efficiency at rated pressures and speeds.

Key Technical Advantages:

• Classic Bent-Axis Dynamics: The signature 40° bent-axis design delivers superior mechanical efficiency and power density. Optimized kinematics minimize friction losses, even during high-pressure operation.

• High-Pressure Distribution System: Valve plates and cylinder blocks undergo nanoscale grinding and specialized heat treatment, providing exceptional cavitation resistance and long-term stability under frequent directional changes.

• Heavy-Duty Bearing Support: Equipped with reinforced roller bearings, the main shaft handles significant radial and axial loads, ensuring minimal vibration and extended operational life even when directly driving heavy loads.

• Superior Sealing Integrity: Featuring high-pressure Viton shaft seals with optimized lip geometry, our pumps effectively prevent oil leakage, ensuring reliability in demanding industrial settings and reducing maintenance intervals.

Application Areas:

• Construction Machinery: Concrete mixer drum drives, crawler crane travel motors, and auxiliary power for compact excavators.

• Industrial Manufacturing: Filter press power units, injection molding auxiliary circuits, and metal forging machinery.

• Marine & Specialized Drives: Marine deck lifting equipment, subsea exploration drilling, and heavy-duty auxiliary hydraulic drives.

Expert Maintenance Tips:

• System Flushing: A2F pumps are sensitive to fluid contamination. Perform a thorough system flush before commissioning and ensure filtration to at least 10µm to prevent wear.

• Case Drain Management: When used as a motor, ensure the case drain port is connected directly to the reservoir. High case backpressure is the primary cause of shaft seal blowout—keep it minimized.

• Monitor for Fluid Emulsification: If the A2F is deployed in outdoor or humid environments, perform periodic fluid sampling. Emulsified oil (water-in-oil) will rapidly corrode the piston group and lead to premature failure.
