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
10 through 18.
Continuous - pump may be run continuously at these ratings.
The performance data show in the graphs are representative of this series. Tests were performed
per SAE specifications using mineral oil with a viscosity of 133 SUS at 49° C [120° F]
