Table 4
Corrected flow     =     Measured flow x 1800 rpm    
Measured rpm Note: Specifications for output flow rates are based on a power shift pressure at the pump of 2400 50 kPa (350 7 psi). The output flow rate changes approximately 7 L/min (1.8 US gpm) for each 100 kPa (14 psi) of power shift pressure in the lower range of the constant horsepower control. The output flow rate changes approximately 3 L/min (0.8 US gpm) for each 100 kPa (14 psi) of power shift pressure in the higher range of the constant horsepower control.Note: Flow measurements must be done only during pressure rise.
