There is described a pumping device (1) for pumping liquids, in particular water, which comprises a pump (30) connectable to a pumping tube (15) which can be immersed in a liquid tank (17) to remove liquid therefrom, and a delivery tube (16) connectable to one or more irrigation devices (18), at least one rechargeable battery (10) for supplying power to the pump (30) and at least one solar panel (3) for charging said rechargeable battery (10). A manual controller (8) is interposed between the rechargeable battery (10) and the pump (30) for manually adjusting the liquid volume to be delivered and the liquid dispensing frequency. The manual controller comprises two rotary knobs (6) and (7) for adjusting the liquid volume delivered by the pump (30) and the actuation frequency of the pump (30), respectively. (Fig. 1) |
