FIELD: motors and pumps.
SUBSTANCE: invention relates to centrifugal modular pumps used for the production of liquids from wells. Centrifugal pump module contains pumping modules with connecting parts made in the form of a plug with annular grooves for locking half rings. Locking semirings are made magnetized. At least one fork is provided with a latch preventing the rotation of the semirings relative to the axis of the pump.
EFFECT: invention is aimed at obtaining a technical result, expressed in reducing the laboriousness of mounting the pump and increasing the reliability of the connection of the pump sections.
