Parker D09AA2A Hydraulic Gear Pump 1.6 Gpm Sae Aa

Product Description

The PARKER D09AA2A is a hydraulic gear pump designed for use in mobile and industrial hydraulic systems. It delivers 1.6 GPM at 2,500 RPM and 1.64 GPM at 1,800 RPM, scaling to 3.27 GPM at 3,600 RPM, with a maximum working pressure of 2,500 psi. The aluminum housing keeps weight low at 2 pounds while maintaining durability under continuous service. The pump mounts on an SAE AA flange and accepts a 0.5-inch shaft. Port connections use 7/8-14 UNF-2B SAE thread on the inlet. Licensed HVAC and fluid-power technicians, mobile equipment mechanics, and industrial maintenance professionals are the typical installers.

The D09AA2A is suited for residential and light commercial hydraulic applications including log splitters, small dump trailers, agricultural equipment, and industrial machine tools requiring a compact, fixed-displacement gear pump. The SAE AA mount and standard SAE port sizing make it a direct fit for common hydraulic power unit configurations. The pump operates across a wide temperature range, from -40 degrees F to 185 degrees F, making it viable in both cold-climate outdoor equipment and indoor industrial machinery.

• Wide operating temperature range: -40 degrees F to 185 degrees F
• Fixed displacement of 0.21 cubic inches per revolution

Compatibility

Designed as an OEM-style replacement or direct-fit pump for hydraulic systems using SAE AA mount interfaces and 7/8-14 UNF-2B SAE port connections with a 0.5-inch input shaft.

Installation Notes

Installation should be performed by a qualified hydraulic systems technician or fluid-power mechanic. Depressurize and isolate the hydraulic circuit completely before disconnecting any lines or removing the existing pump. Verify shaft alignment and ensure the drive coupling is fully seated before torquing the mount fasteners. Follow all applicable equipment manufacturer guidelines and local safety codes when working with high-pressure hydraulic circuits.
