Description & Features

The Danfoss / Eaton Series 26 Gear Pump is designed for a variety of machinery including tractors, harvesters, machine tools, and more. Featuring a 0.50 cu in/rev displacement and a 2-Bolt SAE A mounting flange, this pump ensures efficient, reliable performance in demanding environments.

Minimized noise and vibration are achieved through 13-tooth gears, making it an ideal choice for applications where reduced acoustic output is essential. The 3/4 St.Keyed x 1-1/4 long Shaft and SAE-16 Side Inlet, SAE-10 Side Outlet Ports facilitate smooth integration into hydraulic systems.

Built for durability, the pump's improved mechanical efficiency is bolstered by a bearing lubrication system that uses inlet oil. This pump operates efficiently within a wide temperature range, from -20deg;F to 220deg;F. Rated for a maximum speed of 3600 RPM, it supports continuous duty under stringent conditions.

Rotation is easily reversed by reconfiguring internal parts without the need for extra components, adding to its versatility. This pump can handle a pressure rating up to 3000 psi, making it suitable for various heavy-duty applications.

Product Questions & Answers (2)

Question by: Ross R on Sep 29, 2025, 3:46 PM
got a little tractor with a steering circuit, would this pump make sense for that kind of job
Answer by: Customer Support on Oct 1, 2025, 6:24 AM
For steering circuits and other auxiliary work circuits, this Series 26 single gear pump is a common fit. It is a 0.50 cu in/rev pump rated at 3.9 GPM and it comes set up for clockwise rotation, which lines up well with a lot of tractor and harvester hydraulic setups.
Question by: Shane H on Oct 26, 2025, 6:28 PM
got a setup that spins clockwise. is this pump already set up for CW rotation or do i have to swap anything around?
Answer by: Customer Support on Oct 28, 2025, 6:57 AM
From the factory this one is set up for CW rotation. If you ever need to change direction later, the Series 26 is field reversible by opening the pump, swapping the drive and idler gears, moving the plug, and reassembling. No extra parts are required.
