Eaton Gear Motors

Eaton S26 aluminum Gear Motors will decrease noise emissions / pressure ripples from your hydraulic system. Applications include lift trucks, fan drive systems, turf care, agriculture tractors and harvesters, vibratory machines and industrial.

Product Description


Quiet Operation

The 13-tooth gears, versus 10 teeth in previous pumps, minimizes the flow ripple. This reduces noise as well as vibration.

The improved trap reliefs not only increase power, they also help keep oil flowing smoothly to reduce noise.

Improved Efficiency

Improved bearing lubrication system uses inlet oil instead of high pressure oil, improving volumetric efficiency for more power output.

The highly polished shaft and gears improve mechanical efficiency and reduce wear on these components, adding to the service life and reliability of the pump.

The optimized trapped oil relief areas help reduce pressure ripple for quieter operation. This also decreases the input power requirements.

Field Reversible

The innovative new wear plate permits simple field reversibility of the pump direction. Simply open the pump, switch the drive gear and idler gear, re-position the plug and reassemble. No extra parts are needed.


The Series 26 Gear Pump has been designed to retrofit equipment using the B1 and B2 Gear Pumps. Extra shafts, porting, and mounting configurations, as well as 13 available displacements, give you the choices you need for an easy conversion to this superior pump.
