Parker D05AA2A Hydraulic Gear Pump 0.9 Gpm Sae Aa

Product Description

The PARKER D05AA2A is a hydraulic gear pump designed for use in mobile and industrial hydraulic systems. It delivers 0.9 GPM at 2,500 RPM and 0.89 GPM at 1,800 RPM, with a maximum working pressure of 2,500 psi. The pump features an aluminum housing, a 0.5 inch shaft diameter, and an SAE AA mount configuration. With a displacement of 0.114 cubic inches per revolution, it suits low-to-medium flow applications where compact size and consistent output matter. Licensed hydraulic system technicians and industrial mechanics are the primary installers of this unit.

The D05AA2A fits mobile equipment, agricultural machinery, light industrial equipment, and stationary power units that require a compact gear pump with SAE AA mounting. The 7/8-14 UNF-2B SAE inlet port size aligns with standard SAE hydraulic fittings commonly found in these systems. At 2,500 psi maximum working pressure, the pump handles demanding duty cycles encountered in typical mobile hydraulic circuits. Flow output scales predictably across the operating range, reaching 1.78 GPM at 3,600 RPM for higher-speed drive applications.

Key Features

• 0.9 GPM flow rate at 2,500 RPM with 2,500 psi maximum working pressure
• SAE AA mount for drop-in compatibility with standard hydraulic pump mounting flanges
• 0.114 cubic inches per revolution displacement for consistent, predictable flow output
• Aluminum housing keeps weight low at 2.3 pounds
• Operating temperature range from -40 degrees F to 185 degrees F suits outdoor and mobile environments
• 7/8-14 UNF-2B SAE port thread for direct connection to standard SAE hydraulic lines

Compatibility

Designed as an OEM-style replacement or direct-fit gear pump for hydraulic systems specifying an SAE AA mount, 0.5 inch shaft diameter, and 7/8-14 UNF-2B SAE port connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with SAE hydraulic standards. Depressurize and isolate the hydraulic circuit completely before removing the existing pump or making any connections. Verify shaft alignment and torque all fittings to the system manufacturer specifications using calibrated tools. Inspect all seals and port connections for leaks during initial system pressurization before returning the equipment to service.
