FIELD: mechanical engineering.
SUBSTANCE: invention relates to the field of mechanical engineering. A horizontal multistage sectional centrifugal pump contains two opposed flow paths and a branch body. Each part includes centrifugal impellers and guide units. The body of the outlet is located between two flow parts and contains two outlets of the pumped medium from the impellers, made oppositely with a turn of 180°. Each outlet consists of a blade outlet and a collection channel, while the collection channels are made along a deepening spiral towards each other.
EFFECT: invention allows increasing operational reliability and durability of the pump, increasing efficiency, reducing the vibration level, reducing dimensions of the pump and simplifing production technology of horizontal multistage sectional centrifugal pump branch pipe.
