A loop pump (1) for pumping liquid, i.e. a pump comprising a pipe (3) or the like embodied in a number of turns/loops, said pipe being rotated by a drive source to introduce alternately air and liquid into an inlet (4) and pumping the liquid to a drawing place by way of a conduit (6) or the like rotatably connected with the pipe. The drive source consists of a means, e.g. a propeller (8), absorbing the flow energy of the liquid. A floating body (10) gives the pump the desired floatability on the liquid and the pump comprises means (11) for anchoring it relative to the surroundings of the flowing liquid. |
