PUMP ARRANGEMENT AND METHOD FOR PRODUCING CONTAINMENT SHELL FOR PUMP ARRANGEMENT Russian patent published in 2018 - IPC F04D13/02 

FIELD: engines and pumps.

SUBSTANCE: group of inventions relates to a pump arrangement with a magnetic clutch. Device comprises interior space (11) formed by casing (2) of pump arrangement (1), a containment can (10) with a central longitudinal axis, hermetically sealing the enclosed chamber (12) in relation to interior space (11), impeller shaft (13) rotatable about the axis of rotation, impeller (16) mounted on one end of shaft (13), inner rotor (17) mounted on the other end of shaft (13), outer rotor (24) mounted on drive shaft (20) and interacting with inner rotor (17). Can (10) has a bottom with at least one corrugation (31) entering chamber (12). At least one corrugation (31) is radially disposed at a distance from the central longitudinal axis of can (10).

EFFECT: inventions are directed at creating a pump arrangement in which the eddies of the transport medium inside containment can (10) are reduced without reducing its stability.
