Description & Features

Designed for precision in demanding applications the Danfoss / Eaton Series 26 Gear Pump is optimal for tractors harvesters machine tools and more. Featuring a 2-Bolt SAE A mounting flange and a 3/4 St.Keyed x 1-1/4 long shaft this pump supports a displacement of 0.84 cu in/rev.

With SAE-16 side inlet and SAE-10 side outlet ports the pump ensures efficient fluid handling while operating at a pressure rating of 3000 psi. It includes 13-tooth gears to minimize flow ripple and reduce noise and vibration.

The field reversible pump direction and bearing lubrication system that uses inlet oil instead of high pressure oil significantly enhances mechanical efficiency. This model exhibits a speed rating of 3600 RPM and supports a wide temperature range from -20deg;F to 220deg;F.

Product Questions & Answers (3)

Question by: Dale W on Mar 6, 2026, 10:28 AM
pump says CW rotation on it -- can that be changed out if i end up needing it to spin the other way?
Answer by: Customer Support on Mar 8, 2026, 6:59 AM
Rotation on this pump can be reversed without needing any additional parts. You open it up, swap the drive gear and idler gear, reposition the plug, and put it back together. The wear plate design was built specifically to make that process straightforward. So if your setup ends up calling for counterclockwise rotation down the line, you're not looking at buying a different pump to make it work.
Question by: Eddie R on Dec 13, 2025, 9:55 AM
Will this gear pump work okay on my tractor's hydraulic system? I need something reliable.
Answer by: Customer Support on Dec 15, 2025, 7:13 AM
This Series 26 gear pump is designed for demanding applications like tractors and harvesters, so it should be a good fit.
Question by: Howard W on Dec 12, 2025, 5:26 PM
got a setup that calls for a 2-bolt SAE A mount and a 3/4 keyed shaft, 1-1/4 long. is that what this pump is?
Answer by: Customer Support on Dec 13, 2025, 7:33 PM
Fit-wise it matches those mounting and shaft details. It uses a 2-bolt SAE A mounting flange and a 3/4 straight keyed shaft that is 1-1/4 inches long, with SAE-16 side inlet and SAE-10 side outlet ports.
