Real Specifications
| G-JR positioning | Best-value entry-level pump, AC/DC electrically operated, standard Harrier EZ-JR controller, galvanized steel wetted prime valve | graco-chemical-injection.md |
| Python duty rating | Runs on regulated natural gas or compressed air, CE and ATEX approved, extreme-duty plungers/seals/timing valves | graco-chemical-injection.md |
| Fluid Modules seal options | FFKM, FKM-ETP, HNBR seal materials for aggressive/corrosive chemical compatibility; plunger materials stainless steel or ceramic | graco-chemical-injection.md |
| Fluid packing life | Adjustable fluid packing rated to last up to 25 times longer than non-adjustable seals | graco-chemical-injection.md |
Graco's ND fluid-module option builds in a dedicated leak pathway so a diaphragm/seal failure vents safely rather than letting chemical migrate into the drive section or onto the ground — a direct design response to a common chemical-injection-pump failure mode at a wellhead.
Python and G-JR aren't interchangeable by price point — Python exists because a wellhead in a classified hazardous location can't legally run on a standard AC/DC drive, and that's a code requirement, not an upsell.
