Features Pressures to 35 PSI and flow to 24.1 GPM Quiet Operation The 13-tooth gears, versus 1 teeth in previous pumps, minimizes the flow ripple. This reduces noise as well as vibration.

3 Features Pressures to 35 PSI and flow to 24.1 GPM Quiet Operation The 13-tooth gears, versus 1 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, reposition the plug and reassemble. No extra parts are needed. Interchangeability 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.

Ordering Information Catalog Assemblies Cross Reference Standard catalog assemblies are built from high production parts and are the most economical pump assemblies available in this series. The standard assembly order number is a preassigned part number and may be used to order the specific standard assembly (see pages 1 13). The far right column lists the B1 or B2 pump replaced by the Series 26 pump. 4 EATON Gear Pumps and Motors E-PUGE-MC1-E January 27

16 Model Code - Single Series 26 Gear Pumps can be ordered by using the following Model Code. A twenty-four digit coding system has been designed to identify the features presently available on single gear pumps. The characters and their relative positions within the code identify specific features. Use the Model Code Matrix as an aid when assembling the model code for the pump with the features you desire.

17 Model Code - Multiple Series 26 Gear Pumps can be ordered by using the following Model Code. A thirty-two digit coding system has been designed to identify the features presently available on Multiple gear pumps. The characters and their relative positions within the code identify specific features. Use the Model Code Matrix as an aid when assembling the model code for the pump with the features you desire. It may be helpful to photocopy the matrix and write the numbers and letters into to the boxes as you select features. All thirty-two digits of the code must be submitted when ordering.
