CENTRIFUGAL PUMP WITH TWO CANTILEVERED IMPELLERS AND WITH MOTOR COOLED BY TWO FANS ARRANGED IN SERIES

摘要

Two centrifugal pumps used in parallel and driven by a single electrical motor. The impellers of the pumps are placed at both ends of a shaft, with the motor in between. The motor is cooled by two fans fluidically arranged in series, driven by the pump shaft, and placed on both axial sides of the motor.
