Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Sigma/1-3 Basic capacity | Sigma/1 Basic 17-144 l/h at 12-4 bar; Sigma/3 Basic 146-1,030 l/h at 12-4 bar, ATEX-capable | ProMinent — Metering Pumps, Chemical Transfer Pumps, Tanks, DULCODOS Systems |
| Harrier EZ-JR controller | Standard temperature-based dosing controller, 16A, -40°F to 131°F operating range | Graco — Chemical Injection |
| Harrier+ controllers | Cellular/Modbus remote monitoring, tank level monitoring, patent-pending adaptive flow control technology | Graco — Chemical Injection |
| Multipoint injection capability | Harrier+ MPI / KRAKN MPI dose chemicals to up to 8 injection points from a single pump and controller | Graco — Chemical Injection |
Graco's Harrier+ controllers include smart leak detection and flow verification specifically because an undetected chemical injection leak at a remote wellhead can run for days before anyone notices without cellular alerting.
A wellhead chemical injection pump that fails silently costs money in corrosion and downhole damage long before anyone drives out to check it — Harrier+'s leak-alarm and remote flow-verification features exist because remote unmanned sites are exactly where a silent failure is most expensive.
