Description & Features

The Danfoss / Eaton Series 26 Gear Pump is engineered for demanding industrial applications such as tractors harvesters machine tools and compactors. This single hydraulic gear pump boasts a displacement of 0.66 cu in/rev and features a 2-Bolt SAE A mounting flange.

With a 3/4 St.Keyed x 2 inches long shaft the pump ensures reliable performance with SAE-16 side inlet and SAE-10 side outlet ports optimized for pressures up to 3000 PSI. Operating at a rated speed of up to 3600 RPM this gear pump supports CW rotation and incorporates 13-tooth gears for minimized flow ripple thereby reducing noise and vibration.

Field-reversible pump direction adds flexibility with reconfiguration achievable without additional parts. The innovative bearing lubrication system improves volumetric efficiency by using inlet oil instead of high-pressure oil. A convenient wear plate design facilitates easy rotation change making this pump adaptable for various operational needs.

Product Questions & Answers (3)

Question by: Earl R on Feb 27, 2026, 7:17 AM
pump says CW rotation, can that be switched around if I end up needing it to run the other way?
Answer by: Customer Support on Mar 1, 2026, 7:31 AM
Reversing the rotation is possible without sourcing any extra parts. You open the pump, swap the drive gear and idler gear, reposition the plug, and reassemble. The wear plate design is set up specifically to make that kind of change straightforward. Keep in mind the inlet and outlet ports will also shift when you reverse direction, so plan your hydraulic connections accordingly before you commit to a configuration.
Question by: Phil C on Oct 24, 2025, 11:56 AM
got a tractor setup that needs a clockwise pump, is this one CW and can it be swapped later if i end up needing the other direction?
Answer by: Customer Support on Oct 26, 2025, 6:26 AM
Clockwise rotation is how it ships, and the direction can be reversed in the field by reconfiguring internal parts. The process is to open the pump, swap the drive and idler gears, reposition the plug, then reassemble, and it does not require extra parts.
Question by: Merle M on Jan 14, 2026, 4:05 PM
What kind of machines would this pump be good for? I'm looking at fixing up an old tractor.
Answer by: Customer Support on Jan 16, 2026, 9:37 AM
This gear pump is engineered for industrial applications, including tractors, harvesters, machine tools, and compactors. It's also suitable for steering circuits, sweepers, mowers, lift trucks, fan drive systems, and auxiliary work circuits.
