摘要: Pump with electric motor, immersed in the fluid to be pumped Circuits for the auxiliary circulation of fluid in the pump for the axial balancing and the cooling of specific portions of the pump. The pump comprises a centrifugal region (28) with a fluid axial balancing system (60) and the supply circuit of this balancing system is independent of the or each fluid cooling circuit (90, 50, 48, 52, 86) of specific elements of the pump such as the motor (16) and/or a rolling bearing (38).
