Battery barrel pump

Convenient and eco-friendly watering: Use collected rainwater from a water butt, pond, or IBC container with the flexible battery barrel pump – without needing a tap, power outlet or watering can.


No need for a water connection

The cordless barrel pump is self-sufficient: The device does not need a separate water connection, but instead uses rainwater collected in a water barrel water butt or IBC container. This means that you can water your flowers and vegetable beds in allotments, for example, without needing a water connection.

No need for a power supply

Powerful battery instead of a cable: The barrel pump is battery-operated and does not need a power supply. This enables much more flexibility: On corded products, the area of use is limited by the cable length. By contrast, the barrel pump allows cordless watering even in places where there is no power supply.

More efficient, more ergonomic, simpler: Compared to a watering can, the rain barrel pump offers significantly more convenience. The switch is level with the edge of the barrel, so there is no need for the user to bend down. Carrying heavy watering cans is also a thing of the past as the water is taken directly from the barrel and can be used for watering via the garden hose and garden sprayers.

Watering with the battery barrel pump


The barrel pump also fits through narrow openings such as those in an IBC container. This saves time and water as the rainwater collected can be easily reused.
