Description
Overview
This flow control switch automatically starts the pump when pressure decreases (for example, when a tap is opened) and stops it when there’s no flow or a water shortage (for example, when a tap is closed). It’s suitable for both drinking water and non-potable water piping systems.
Performance range
- Flow: 0 to 15 m³/h
- Starting pressure: 1.2 bar
- Maximum pressure: 10 bar
- Cut-in pressure adjustable between 1.2 and 1.5 bar
Operating limits
- Pipe water temperature: 0–60°C (not frozen)
- Ambient temperature: 0–45°C
Important installation note
- Use a separate non-return valve with this device — one is not built in
