The barrel pump BP 1 Barrel is the perfect replacement for a watering can. With the barrel pump watering is a piece of cake and carrying heavy watering cans is a thing of the past. It is not just your back that is protected. But your purse also gets off lightly with this watering pump. Expensive drinking water is saved thanks to free, nutrient-rich rain water from the water butt. The innovative barrel mounting clamp provides optimal stability and guarantees effective garden watering that pays off. In addition, there is an integrated on/off switch on the barrel mounting clamp with which the pump can be switched on and off again comfortably and in a time- and energy-saving manner.
