PUMPS

The John Blue pump setting wrench is used to adjust the pump's output by rotating the setting hub. This allows for precise control of the flow rate, particularly useful when calibrating the pump for specific applications like liquid fertilizer application. The wrench facilitates the adjustment of the setting pointer, which corresponds to a specific pump output.
