FIELD: non-positive-displacement pumps.

SUBSTANCE: clutch comprises outer and inner clutch members interconnected through flexible members arranged in rows over concentric circumferences of different diameter and locator for flexible members. The members are set in cylindrical sockets. The sockets are made of semi-cylindrical bores provided in the clutch members at different diameters. The diameter of sockets of periphery row are greater than that of the inner one. The clutch is provided with split distant and centering rings and slot bushings which are connected with the corresponding clutch members for permitting longitudinal movement with respect to the washers. The inner diameter of one of the bushings is equal to the outer diameter of the end of the pump shaft. The inner side of the other washer is conical, mating the cone of the end of the electric motor shaft, and is pressed to its surface by a nut. The distant ring is in a contact with the face surface of the slot washer from the side of the pump, has the same inner diameter, and is locked by the centering ring which embraces it from the outer side.
