Problem: manual pump and valve operation limits the system
Common starting points:
- Pump start/stop is manual → labor, inconsistent run times
- Too many manual valves → hard to enforce zoning when water is limited
- No schedules or records → weak traceability for commercial operations
- Pipes are in the ground, but control logic never caught up
Retrofit focuses on control and zoning, not replacing the whole hydraulic network.
Solution: add controller, pump control, valve automation, and scheduling
A practical retrofit stack:
| Layer | What you add |
|---|---|
| Smart controller | Schedules, interlocks, zone sequencing |
| Pump control | Safe start/stop, pressure/flow awareness where specified |
| Valve automation | Zone-by-zone irrigation instead of ad-hoc manual switching |
| Records / remote | Optional remote access or wireless expansion later |
Design usually follows: existing water source → available flow → time window → zones → automation.
Before / after (diagram placeholder)
Before: manual pump operation, manual valves, limited scheduling.
After: controller-led zoning, automated valves, structured irrigation windows—same main pipes in most projects.
Product combination (typical retrofit BOM)
| Item | Purpose |
|---|---|
| Controller cabinet / panel | Core scheduling, I/O, and project logic |
| Pump control | Relays, starters, or signals matched to the existing pump setup |
| Valve control | Solenoid or actuator drivers per zone |
| Sensors (optional) | Flow, pressure, tank level—where the specification requires feedback |
| Wireless expansion (optional) | e.g. LoRa valve nodes when field wiring is costly |
Partner value: easier retrofit projects for local service providers
- Keep existing pipelines → less civil work, clearer upgrade scope
- Staged upgrades → pump first, then zones, then remote—matched to budget and season
- Repeatable packages for distributors selling into contractor networks
- OEM / batch paths when partners want a standard controller + I/O kit for their market
Upgrade levels (short reference)
- Timed pump control — reduce manual switching
- Multi-zone sequencing — match limited flow to farm layout
- Remote / wireless — LoRa or gateway paths where wiring is painful
- Fertigation / sensors — when the project moves beyond basic irrigation
Exact staging depends on the existing pump, electrical, and valve locations.
