Notable enums
The 18 enums classify pump operation:
- Operating mode — local / remote / manual / automatic
- State — running, stopped, faulted, maintenance
- Hydraulic conditions — cavitation, dry-running, suction starvation
- Alarm severity — informational, warning, alarm
Notable types
The single DTO covers pump-curve / operating-point summary — the performance metadata a pump server reports.
