The device is used for supplying water in and around the house. After commissioning, the de- vice switches the pump on and off, depending on the pressure. The pump draws water via the suc- tion line and conveys it to the storage vessel. When the storage vessel is full, the pump switch- es off again. If water is drawn off, the pump switches on again automatically and conveys wa- ter to the tapping point. The storage vessel is then filled again.

2.4 INOX (stainless steel)

Pumps with the designation "INOX" are made of stainless steel. This does not affect their design or function.

2.5 Safety and protective devices
