Quiet Operation• The 13-tooth gears, versus 10 teeth in previous pumps,

minimizes the flow ripple. This reduces noise as well asvibration.

• The improved trap reliefs not only increase power, they alsohelp 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 morepower output.

• The highly polished shaft and gears improve mechanicalefficiency and reduce wear on these components, adding tothe service life and reliability of the pump.

• The optimized trapped oil relief areas help reduce pressureripple for quieter operation. This also decreases the inputpower 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 andreassemble. 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 availabledisplacements, give you the choices you need for an easyconversion to this superior pump.

Ordering InformationCatalog Assemblies Cross ReferenceStandard catalog assemblies are built from high productionparts and are the most economical pump assemblies availablein this series. The standard assembly order number is a

preassigned part number and may be used to order the specificstandard assembly (see pages 10–13). The far right columnlists the B1 or B2 pump replaced by the Series 26 pump.
