Parker D11AA2A Hydraulic Gear Pump 2 Gpm Sae Aa Mount

Product Description

The PARKER D11AA2A is a hydraulic gear pump designed for use in mobile and industrial hydraulic systems where consistent, reliable fluid delivery is required. It delivers 2.04 GPM at 1,800 RPM and 4.08 GPM at 3,600 RPM, with a maximum working pressure of 2,500 psi. The pump features a 1/2-inch shaft diameter, an SAE AA mount configuration, and a 7/8-14 UNF-2B SAE port connection. The aluminum housing keeps weight low at 2.1 pounds. This unit is typically installed by hydraulic system technicians and equipment mechanics working on power units, utility vehicles, and auxiliary drive applications.

The D11AA2A is suited for residential and light commercial hydraulic power unit builds as well as OEM equipment installations requiring a compact, low-displacement gear pump. Its SAE AA mount and standard SAE port sizing make it compatible with a wide range of common hydraulic manifolds and pump mounts. The rated maximum speed of 2,500 RPM and displacement of 0.262 cubic inches per revolution position this pump for low-flow, moderate-pressure circuits. It operates across a broad temperature range, from -40 degrees F to 185 degrees F, making it practical for outdoor and all-season equipment.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and de-energize the hydraulic system completely before removing or installing the pump. Verify shaft alignment with the drive source before final mounting to prevent premature wear. Torque all port fittings and mounting hardware to the hydraulic system manufacturer specifications and follow applicable hydraulic system safety codes for your jurisdiction.
