It delivers 4.99 GPM at 1,800 RPM and 9.99 GPM at 3,600 RPM, with a rated output of approximately 5 GPM at 2,000 RPM. Maximum working pressure is 2,000 psi. The pump uses an SAE AA mount configuration and accepts a 1\/2 inch shaft. Inlet and port connections are 7\/8-14 UNF-2B SAE. The aluminum housing keeps weight low at 3 pounds, making it suitable for compact hydraulic circuit installations. Licensed hydraulic system technicians and fluid power specialists are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe D27AA2A is suited for light-duty hydraulic systems on compact equipment, small industrial machinery, and mobile platforms requiring a reliable fixed-displacement gear pump. Its SAE AA mounting pattern fits standard auxiliary pump pads on small engines and PTOs. The operating temperature range of -40 degrees F to 185 degrees F supports both cold-start and continuous-duty applications. At 0.641 cubic inches per revolution displacement, it is sized for systems that prioritize flow efficiency in a small envelope.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDelivers 4.99 GPM at 1,800 RPM and 9.99 GPM at 3,600 RPM for flexible speed-range operation\u003c\/li\u003e\n  \u003cli\u003e2,000 psi maximum working pressure for light to medium hydraulic circuit demands\u003c\/li\u003e\n  \u003cli\u003eSAE AA mount with 7\/8-14 UNF-2B SAE port threading for direct OEM-style installation\u003c\/li\u003e\n  \u003cli\u003e0.641 cubic inches per revolution fixed displacement for predictable flow output\u003c\/li\u003e\n  \u003cli\u003eAluminum housing reduces overall system weight at 3 pounds installed\u003c\/li\u003e\n  \u003cli\u003eWide temperature range from -40 degrees F to 185 degrees F supports year-round operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit gear pump for hydraulic systems requiring an SAE AA mount, 1\/2 inch shaft diameter, and 7\/8-14 UNF-2B SAE port connections at up to 2,000 psi working pressure.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified fluid power technician or hydraulic systems specialist. Depressurize and lock out the hydraulic system fully before removing or installing the pump. Ensure shaft alignment with the drive coupling before final mounting to avoid premature bearing wear. Follow applicable fluid power standards and equipment manufacturer guidelines for torque and plumbing practices.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 4.99 GPM at 1,800 RPM; 9.99 GPM at 3,600 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 2,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplacement\u003c\/strong\u003e: 0.641 cubic inches per revolution\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: SAE AA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Port Size\u003c\/strong\u003e: 7\/8-14 UNF-2B SAE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: SAE UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 185 degrees F (85 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F (-40 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D27AA2A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539479593266,"sku":"D27AA2A","price":530.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16823f487360a64ab2512124a77f071f.jpg?v=1785841189","url":"https:\/\/voomisupply.com\/products\/parker-d27aa2a-hydraulic-gear-pump-5-gpm-sae-aa-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
