Product description "The GARDENA Barrel Pump on battery 2000/2 18V P4A is light, robust and durable – and works even when there is no power supply. The length of the aluminum telescopic pipe can be adjusted to the height of the rain barrel. The pump's delivery capacity is 2,000 litres per hour and the maximum pressure is 2.0 bar. In combination with a GARDENA nozzle, spray gun or sprinkler, shrubs, flowers and lawn are optimally supplied with water. The flow rate can be adjusted as needed thanks to the control valve – drip irrigation is also possible. The duration of watering can be preset by a timer (5, 10 or 15 minutes) and then switches off automatically. If the rain barrel is already empty before that, a dry running protection ensures that the pump is not damaged. An easy-to-clean pre-filter keeps dirt out. Of course, the garden pump can not only be used in rainwater barrels, but also for other pumping tasks. The barrel pump 2000/2 is supplied as a ready-to-use set with a charger and an 18V POWER FOR ALL battery with a running time between 18 and 65 minutes, depending on the selected ... mode. The POWER FOR ALL ALLIANCE is one of the largest cross-brand battery alliances of leading manufacturers worldwide. The battery can be used for numerous other devices in the home and garden – so you can save money and still remain flexible."
