Pump regulator (drive pump)
Typical example
(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).
