Rexroth AZP Series Double Gear Pump | AZPGG-11-038/038 | 0510768011 | AZPF AZPN

The Rexroth AZP Series from LIC Hydraulic represents the pinnacle of External Gear Pump technology. Categorized into frame sizes AZPF, AZPN, and AZPG, these pumps are the preferred choice for mobile and industrial applications worldwide. The model AZPGG-11-038/038 (Part No. 0510768011) is a tandem (double) gear pump designed to power two independent hydraulic circuits from a single engine drive. We provide 100% drop-in replacements, matching original Bosch Rexroth specifications for mounting flanges, shaft splines, and volumetric efficiency.

Technical Highlights

• Part Number: 0510768011 (AZPGG-11-038/038).

• Displacements: $38\text{ cc}$ (Front) + $38\text{ cc}$ (Rear).

• Max Pressure: Continuous duty up to $250\text{ bar}$ ($3625\text{ psi}$), Intermittent up to $280\text{ bar}$.

• Material: High-strength aluminum alloy body with hardened steel gear sets.

Core Advantages

• Axial Gap Compensation: Featuring floating bushings that automatically adjust to internal pressure, our pumps maintain peak efficiency throughout the entire service life, even under varying temperature cycles.

• High-Performance Drive Shafts: Engineered to withstand high radial and axial loads, the AZPG series is ideal for direct coupling to engine PTOs or belt-drive configurations.

• Silent Operation: The precision-engineered gear teeth profile reduces flow ripple and mechanical vibration, meeting the strictest noise emission standards for modern industrial workshops.

• Seal Integrity: Equipped with premium Viton/NBR shaft seals that handle high case pressures, preventing leaks and ensuring long-term reliability in dusty or humid environments.

Expert Maintenance Tips

• Shaft Alignment: When installing the 0510768011, ensure the pump shaft is perfectly aligned with the drive motor. Misalignment is the #1 cause of bearing failure and shaft seal leaks.

• Filtration Standard: Maintain hydraulic oil cleanliness at ISO 19/17/14 or better. Gear pumps are robust, but particle contamination will score the side plates and reduce discharge pressure over time.

• Air Prevention: Check the suction line for any pinhole leaks. Air ingress (aeration) will cause high-pitched whining and rapid cavitation damage to the aluminum housing.
