Adjust the pump output flow if the flow test results are not within specification. Refer to Illustration 1 for more information on pump output flow adjustments.ReferenceRefer to Testing and Adjusting, "Main Pump (Flow) - Test (Constant Horsepower Flow Control)" for pump flow specifications.Adjustment of Pump Output Flow (Constant Horsepower Control)

Pump regulator (drive pump) (1) Pump regulator (drive pump) (2) Pump regulator (idler pump) (3) Locknut (4) Adjustment screw (first stage of constant horsepower control) (5) Locknut (6) Adjustment screw (second stage of constant horsepower control)Adjust the flow of the drive pump for the first stage of the constant horsepower control. The idler pump must be at no-load condition.
Loosen locknut (3) .
Turn adjustment screw (4) in order to adjust the output flow of the pump. Turning adjustment screw (4) clockwise will increase the output flow of the pump. Turning adjustment screw (4) counterclockwise will decrease the output flow of the pump. A 1/4 turn of adjustment screw (4) will change the output flow of the pump at the following pressure.
Output flow of the pump will change approximately 13.5 L/min (3.6 US gpm) if the output flow is adjusted in the pressure range of 11800 kPa (1700 psi) to 19600 kPa (2850 psi).
