PCT No. PCT/SE86/00479 Sec. 371 Date Jun. 15, 1987 Sec. 102(e) Date Jun. 15, 1987 PCT Filed Oct. 16, 1986 PCT Pub. No. WO87/02425 PCT Pub. Date Apr. 23, 1987.A loop pump (1) for pumping liquid, i.e. a pump comprising a pipe (3) or the like embodied in a plurality of turns/loops. The pipe is rotated by a drive source to introduce alternately air and liquid into an inlet (4) and to pump the liquid to a drawing place by way of a conduit (6) or the like rotatably connected with the pipe. The drive source, which may be a propeller (8), absorbs the flow energy of the liquid. A floating body (10) gives the pump the desired floatability on the liquid and the pump includes an anchor (11) for anchoring it relative to the surroundings of the flowing liquid.
