Harrier® Series Controllers

Graco AC and DC electrically powered Harrier controllers offer basic off/on time control with the Harrier EZ and enhanced smart control capabilities with Harrier+ controller. Harrier+ remotely manages chemical injection pumps and has tank level monitoring via SCADA or through cellular connectivity.

Injection Rate Control Options

Three rate control types: Time, Cycle and Flow

Time Control Summary

In Time mode, you can choose the On time and Off time. Adjusting the On and Off times allows the user to control both dosing of chemical along with the frequency at which the pump runs. Time mode is advantageous when direct control of the pump's run time is required.

Cycle Control Summary

In Cycle mode, you can choose the number of cycles per minute. The maximum rate is 60 cycles per minute and will result in a constant running condition.
Cycle mode is advantageous when the highest possible level of chemical rate injection is required.
