GRACO 25T650 – G-JR Solar DC Operated Chemical Pump Including the Harrier EZ-JR Controller, 1/4″,

GRACO 25T650 – G-JR Solar DC Operated Chemical Pump Including the Harrier EZ-JR Controller, 1/4″, 2000 PSI

12 VDC G-JR Solar DC Operated Chemical Injection Pump designed for reliable chemical dosing in remote locations. This complete system includes the Harrier EZ-JR controller and temperature probe for automated chemical injection applications where AC power is not available.

Built with same quality standards as other Graco chemical injection pumps, the G-JR is simple to operate, easy to service and offers the lowest up front cost. Offered in DC solar or AC electric, the pumps come standard with the Harrier EZ-JR controller which offers a similar set of features as the current Harrier EZ controller.
