The invention relates to submersible pump with a transmission (10) and a compensator (24). The transmission (10) comprises a transmission housing (12) filled with a lubricating fluid. Said transmission housing accommodates a driven input shaft (14, 102, l20) and an output shaft (16) for driving a pump. A transmission step (22) is provided which slows down the rotational movement of the input shaft (14, 102, 120). The compensator (24) adjusts the lubricating fluid pressure in the transmission housing (12) to the ambient pressure. The compensator (24) is arranged within the transmission housing (12) adjacent to the transmission stage (22) and distributes the heat building up at the transmission stage (22) across the lubricating fluid.
L'invention concerne un dispositif à pompe submersible comprenant une transmission (10) et un compensateur (24). La transmission (10) comporte un carter de transmission (12) rempli de fluide lubrifiant et dans lequel sont logés un arbre d'entrée actionnable (14, 102, 120) et un arbre de sortie (16) pour l'actionnement d'une pompe. Un étage de transmission (22) sert à ralentir le mouvement de rotation de l'arbre d'entrée (14, 102, 120). Le compensateur (24) adapte la pression du fluide lubrifiant dans le carter de transmission (12) à la pression ambiante. Pour mieux répartir la chaleur générée au niveau de l'étage de transmission (22) par l'intermédiaire du fluide lubrifiant, le compensateur (24) est logé à l'intérieur du carter de transmission (12), à côté de l'étage de transmission (22).
