Geometric efficiency pumps
In the catalog geometric efficiency hydraulic pump unit is given in cm3 / rev.
In practice, however, is often required pump capacity in liters per minute.
This indication is directly dependent on the speed of the pump.
Yield geometric liters per minute can easily be calculated:

The number of rotations x efficiency geometric

1000

Pump speed must be administered as a unit rev / min, and the geometric efficiency as cm3 / rev to get the result in
unit liters / min.
When checking the speed ratio must take into consideration the number of engine revolutions.
