Harrier EZ-JR ships standard on Graco's G-JR wellhead chemical injection pump specifically because "one plunger size, one seal material takes the guesswork out of speccing a pump" — a vendor-stated design choice to reduce field-configuration error at remote wellhead sites.
A remote wellhead controller has to survive -40°F winters on battery or solar power with no line power nearby — Graco's Harrier EZ-B is rated down to -40°F and ships as a solar/DC unit specifically for that duty, while the Harrier+ line adds cellular/SCADA remote monitoring for sites where a technician can't drive out every time a chemical tank runs dry.
