EXCERPT:
Pump Efficiency Check
NOTE: The steering pump must be checked on a bench that simulates the machine's complete steering hydraulic system. The charge pump and differential lube pump can be checked on the machine or a standard bench.
For any pump test, the pump flow measured in liter/min (U.S. gpm) at 690 kPa (100 psi) is larger than the pump flow at 6900 kPa (1000 psi) at the same speed.
The difference between the pump flow of two operating pressures is the flow loss.
Method of finding flow loss:
