The Battery Rainwater Tank Pump 2400ComfAuto 18V P4A solo gives you control of your irrigation system, even when you’re not there, thanks to stepless power adjustment and automatic pump timer functionalityAutomatic operationWhen watering manually, the auto on/off feature starts and stops the pump when the nozzle is opened or closed, saving battery runtime and meaning the pump will operate for longer on a single charge compared to continuous operation.Scheduled irrigation controlWhen you’re not at home your plants can be at the mercy of the elements but with the irrigation control function you can protect your garden from drought and ensure everything is watered at regular intervals: Dial in your watering schedule and set the irrigation controls, for peace of mind when you can’t be in the garden.Stepless power adjustmentThe stepless power adjustment feature gives you control over the maximum flow rate of 2,400 l/h. Find a balance between power and runtime and you can dial in pressure levels that work for your garden. Long battery runtimes are between 25 - 76 minutes at 2.5 Ah and 40 - 122 minutes at 4 Ah. Automatic switch offThe Battery Rainwater Tank Pump can run unattended once started, using the 5-, 10- or 15-minute timer functions and automatic switch off. Thanks to this, the pump helps avoid unnecessary battery and water use and you don’t need to wait around or remember to go back and turn it off again.Steady Pressure technologyThe built-in Steady Pressure technology means you won’t experience any drop off in performance as the battery runs down and its voltage decreases. And there won’t be any drop off after the initial starting phase. In fact, you get a constant performance level of over 90% throughout the pump runtime, with a maximum flow rate of 2,400 l/h and a maximum pressure of 2.1 bar.
