Series 26 PumpFeatures
Quiet Operation
• The 13-tooth gears, versus10 teeth in previouspumps, minimizes the flowripple. This reduces noiseas well as vibration.
• The improved trap reliefsnot only increase power,they also help keep oilflowing smoothly to reducenoise.
Improved Efficiency
• Improved bearing lubrica-tion system uses inlet oilinstead of high pressureoil, improving volumetricefficiency for more poweroutput.
• The highly polished shaftand gears improvemechanical efficiency andreduce wear on thesecomponents, adding to theservice life and reliability ofthe pump.
• The optimized trapped oilrelief areas help reducepressure ripple for quieteroperation. This alsodecreases the input powerrequirements.
Field Reversible
• The innovative new wearplate permits simple fieldreversibility of the pumpdirection. Simply open thepump, switch the drivegear and idler gear, reposi-tion the plug and reassem-ble. No extra parts areneeded.
Interchangeability
• The Series 26 Gear Pumphas been designed toretrofit equipment usingthe B1 and B2 GearPumps. Extra shafts, port-ing, and mounting configu-rations, as well as 13 avail-able displacements, giveyou the choices you needfor an easy conversion tothis superior pump.

Catalog Assemblies CrossReference
Standard catalog assemblies arebuilt from high production partsand are the most economicalpump assemblies available in thisseries. The standard assembly
order number is a preassignedpart number and may be used toorder the specific standardassembly (see pages 10–13). Thefar right column lists the B1 or B2pump replaced by the Series 26pump.

A twenty-four digit codingsystem has been designedto identify the featurespresently available on singlegear pumps. The charactersand their relative positions
within the code identify spe-cific features.
Use the Model Code Matrixas an aid when assemblingthe model code for thepump with the features youdesire. It may be helpful tophotocopy the matrix and
write the numbers and let-ters into the boxes as youselect features.
All twenty-four digits of thecode must be submittedwhen ordering.

The excess flow (EF)is avail-able for auxiliary circuits.Theresponse time was select-edto insure that the operatorwill not sense a delay orsteering “kick”during tran-sient conditions.

A twenty-four digit codingsystem has been designedto identify the featurespresently available on singlegear pumps. The charactersand their relative positions
within the code identify spe-cific features.
Use the Model Code Matrixas an aid when assemblingthe model code for thepump with the features youdesire. It may be helpful tophotocopy the matrix and
write the numbers and let-ters into the boxes as youselect features.
All twenty-four digits of thecode must be submittedwhen ordering.

L2 gear pumps can beordered by using the follow-ing Model Code.
A twenty-three digit codingsystem has been designed toidentify all of the features avail-able on L2 single gear pumps.The characters and their rela-tive positions within the codeidentify specific features.
Use the Model Code Matrixas an aid when assemblingthe model code for thepump with the features youdesire. It may be helpful tophotocopy the matrix andwrite the numbers and let-ters into the boxes as youselect features.
All twenty-three digits of thecode must be submittedwhen ordering. The sevenzeros at the end of themodel code are for factoryuse, be sure to includethem when ordering.
