Pressures to 3500 PSI and flow to 24.1 GPM
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 wea 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.

\*Multiple pump input torque limitations:
The total torque for multiple pump displacements and pressure combinations cannot exceed the maximum input torque rating of the shaft. The proper formula is pressure times displacement divided by 6.28.

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. It may be helpful to photocopy the matrix and write the numbers and letters into the boxes as you select features.
All twenty-four digits of the code must be submitted when ordering.

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 the boxes as you select features.
All thirty-two digits of the code must be submitted when ordering.

Series 26 pump Load sensing priority valve
The Load Sensing Priority Valve is used with the open loop load sense systems that are typically used in steering and braking circuits. The load sense gear pump provides metered priority flow (CF) on demand.
The excess flow (EF) is available for auxiliary circuits. The response time was selected to insure that the operator will not sense a delay or steering "kick" during transient conditions.

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. It may be helpful to photocopy the matrix and write the numbers and letters into the boxes as you select features.
All twenty-four digits of the code must be submitted when ordering.

Ordering information Standard catalog assemblies
Standard Catalog Assemblies are built from high quality production parts and are the most economical pumps available in this series. Dimensions and order numbers for Standard Catalog Assemblies are given on pages 29-30.
Optional configurations
Besides the Standard Catalog Assemblies, the L2 Series has several optional features. Flow divider and tandem backplates are available. Multiple gear pumps can also be built. If a variation from the Standard Catalog Assemblies is required, use the model codes on pages 35-36.

Series L2 Pump Model code - single
L2 gear pumps can be ordered by using the following Model Code.
A twenty-three digit coding system has been designed to identify all of the features available on L2 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. It may be helpful to photocopy the matrix and write the numbers and letters into the boxes as you select features.
All twenty-three digits of the code must be submitted when ordering. The seven zeros at the end of the model code are for factory use, be sure to include them when ordering.
