Chemical Injection Pump — Hydrocarbons/Fuels/Oils
Named chemicals
What LibertyCES's vendor documentation shows
The family the whole Graco chemical-injection line exists for — methanol injection at gas wellheads to prevent hydrate formation, plus corrosion and solids inhibitors into hydrocarbon streams. The FFKM / FKM-ETP / HNBR seal ladder is the real compatibility axis and the reason Wolverine is quoted to spec when G-JR/Python's fixed configurations do not fit. Python's natural-gas-motive design is genuinely distinctive: the host stream powers the pump, so no electricity is needed in a classified area. Real cross-reference flagged: Graco maintains an 'ONG Chemical Compatibility Guide' and 'Python Pump Configurator' as separate tools, not yet captured.
Materials documented for this service

FAQ
Is Chemical Injection Pump compatible with Hydrocarbons/Fuels/Oils?
The family the whole Graco chemical-injection line exists for — methanol injection at gas wellheads to prevent hydrate formation, plus corrosion and solids inhibitors into hydrocarbon streams. The FFKM / FKM-ETP / HNBR seal ladder is the real compatibility axis and the reason Wolverine is quoted to spec when G-JR/Python's fixed configurations do not fit. Python's natural-gas-motive design is genuinely distinctive: the host stream powers the pump, so no electricity is needed in a classified area. Real cross-reference flagged: Graco maintains an 'ONG Chemical Compatibility Guide' and 'Python Pump Configurator' as separate tools, not yet captured. This is strong evidence.
