Product Description
The IDROMAT combines a flow and pressure sensor with an intelligent electronic controller to automatically start and stop a water pump whenever a tap opens or closes. It maintains constant pressure while delivering the demanded flow — replacing separate pressure switches, check valves, and dry-run protection devices with a single compact unit.
How does the dry-running protection safeguard the pump?
When the IDROMAT detects water shortage, it immediately stops the pump to prevent damage. The automatic reset function then attempts up to 10 restarts over 24 hours. If water returns, normal operation resumes automatically. If not, the FAILURE LED illuminates and a manual RESET is required — protecting the pump while avoiding unnecessary service calls for transient shortages.
Which IDROMAT model fits which pump size?
| Model | Max Current | Restart Pressure | Best For |
|---|---|---|---|
| IDROMAT 3 | 8 A (16 A start) | — | Small domestic pumps |
| IDROMAT 4 | 16 A (30 A start) | — | Medium domestic pumps |
| IDROMAT 5 | 16(8) A / 1.5 kW | 1.2–3.0 bar (fixed) | Domestic with specific restart needs |
| IDROMAT 5e | 16(8) A / 1.5 kW | 1.5–2.5 bar (adjustable) | Applications needing tuning flexibility |
| IDROMAT 6 | 30(16) A / 2.2 kW | 1.5 or 3.0 bar | Larger pumps, higher flow (12 m³/h) |
Built-In Protections
- Dry-running protection with automatic reset
- Anti-jamming — brief pump run (~5 s) if idle for 24 hours
- Closed-port protection — prevents operation against blocked discharge
- Anti-water hammer — integrated check valve with non-return damping
Installation Requirements
- Mount horizontally on a vertical pipe, arrows pointing upward
- Inlet connects directly to pump outlet; device outlet goes to the distribution network
- Do not add a second check valve on the IDROMAT outlet
- For submersible pump installations, add an auxiliary 20 L membrane tank
