Description & Features

The Danfoss / Eaton Series 26 Gear Pump offers exceptional reliability and performance for heavy-duty applications. With a displacement of 0.66 cu in/rev and a 2-Bolt SAE A Mounting Flange this single hydraulic gear pump is designed for use in tractors machine tools and steering circuits.

Innovative 9-tooth SAE A splined shaft ensures optimal torque transmission while the SAE-16 side inlet and SAE-10 side outlet ports provide efficient fluid management. Constructed for clockwise rotation the pump supports a rated flow of 5.1 GPM at 3600 RPM.

Advanced wear plate technology allows for easy pump rotation changes. The bearing lubrication system which utilizes inlet oil enhances volumetric efficiency. Additionally the 13-tooth gears minimize flow ripple contributing to reduced noise and vibration.

Suitable for use in various equipment such as compactors sweepers and rotary mowers this pump operates within a temperature range of -20deg;F to 220deg;F. It offers a maximum continuous operating pressure of 3000 PSI and features an easily reversible design for flexible application needs.

Product Questions & Answers (2)

Question by: Frank M on Jun 1, 2025, 5:40 PM
Will this gear pump work on my tractor's hydraulic system, or is it more for industrial equipment?
Answer by: Customer Support on Jun 3, 2025, 6:42 AM
This Series 26 gear pump is suitable for tractors and harvesters, along with machine tools and steering circuits. It's also used in compactors, sweepers, rotary mowers, lift trucks, and auxiliary work circuits.
Question by: Denise C on Nov 3, 2025, 2:01 PM
got a setup that needs a clockwise pump, 2-bolt SAE A mount, and a 9-tooth SAE A spline. Is this one that exact combo?
Answer by: Customer Support on Nov 5, 2025, 8:45 AM
The key callouts on this pump are CW rotation, a 2-bolt SAE A mounting flange, and a 9-tooth SAE A splined shaft. Porting is side inlet SAE-16 and side outlet SAE-10, so it matches that layout as well.
