  1. [ŐOIOj in fact, it is also an advantage of the present invention that it is made possible to eliminate floating matter 'without- the pump, being on a base foot. One can achieve this elimination even if the pump is provided with mounting mentis on a tripod. [1)0515 EP 1 739 3 i 1 describes devices located in the pit which serve to gttide the liquid to be pumped in order to prevent the creation of vor! ices on the surface of the body of water. These devices tes ties! form part of the pump unit as such. One seeks to reduce the speed of the water, whereas according hi the present invention it is increased by the relatively small second portion in order to hotter carry along the floating matter. The pump unit according to the invention is of it type as is described in this prior document, which has tto base foot and no supply zone delimited by wails parallel to the ax is of the unit. 10012 J in the attached drawings, given purely by way of example: figure 1 is a sectional view of a pumpunit according to the invention, whereas f igure 2 is a partial plan view from below. {00X3j The pump unit shown in Figure 1 comprises a shaft I that defines the vertieai axis of the tutit, the shah 1 farms the rotor of an electric motor, the stator of which is identified by 2. An impeller 3 is wedged on the bottom portion of the shaft 1, An aspiration bolton! 5 is irxed by screws 4 beneath the impeller. The bottom 5 has a vertical annular external wall 6 and a vertical annular internal wall 7. The internal wall is closer to the shaft 1 In the horizontal direction, the wall 6 being further away. The wall 7 delimits an aspiration gift. The external wail 6 del inti is an aspiration zone 10. A first portion 1Í of the lower free edge 12 of the external wall 6 is at a lower level than the lower free edge 13 of the internal wall 7. However, the lower free edge 14 of a second portion 15 of the external wall 6 is at a level higher than the lower edge 1.3 of the internal wall 7. The second portion 15 is inclined by an angle of 31)- to 60° and its angle at the centre is 120°. This small angle means that the water which carries along the iloating matter which is sucked up moves at high speed. {00141 The lkjaid sucked up by. the .aspiration gill is discharged by a pressure pipeline 16, The unit is supported on a tripod 17. (0015{ The second portion IS is located on the side of the unit which is opposite to the side where the pressure pipeline 16 is, [011161 The unit is mounted by positioning its axis vertically. A unit according to the invention is able to effectively pump the iloating matter without it being necessary to incline it, Motoros szivatiyúegység Szätbndäimi igénypontok I, Függőleges tengelyű (il motoros szivaítyúegység, amely egy eszközzel van ellátva egy talpazatra vagy egy háromlábú állványra fi?) történd felszereléshez, és amely alul egy szivófenékkei (5) rendelkezik, amelynek gyűrű alakú függőleges belső Sala (7) egy szwányilást (9) határol és amely szivóíenék (5) gyűrd alakú függőleges külső falának (6) szele egy beömlési tartományt {löí határol, ahol a külső fai (6) szabad alsó szélének (52) első része (11) alacsonyabb szinten helyezkedik el, mint a belső fal (7) szabad alsó széle (13), «53»/ hogy a külső fal (6) második részének (15) szabad alsó széle magasabb szinten helyezkedik el, mint a belső fai (?) alsó széle ( 13).
