An automatic device with a self-priming pump for using rainwater in applications where potable water is not required. It is suitable for watering the garden, flushing toilets, laundry, and more. In case of a shortage of rainwater, the device switches to a secondary source.

The device is suitable for family homes and small commercial properties. Its compact design allows for easy and immediate connection and commissioning. The operation via a touch LCD display is simple and intuitive. Additionally, the device features automatic protective functions such as level monitoring and dry running protection, continuous pressure indication in the device, and memory of the last 10 faults.

A base frame with dampers reduces vibrations caused by the pump, ensuring quiet operation. An 11-litre pre-tank with a float valve and overflow sensor is installed with the pump.

We recommend connecting it with a sludge pump, which is placed in the rainwater tank.
