Operating assembly for pumps for recirculating a cooling fluid of combustion engines and recirculating pump provided with such an operating assembly

An operating assembly for operating a pump for recirculating a cooling fluid of a vehicle, comprising:

• a driven shaft (2) extending axially with a front end (2a) designed to carry the impeller (1) of a pump;
• an electromagnetic friction clutch (220) arranged between a movement take-up element (223,223a) for taking up a rotational movement and the driven shaft (2);
• an electric drive (30) for driving the driven shaft (2), independent of the movement take-up element;
• a support body (11;113) extending axially between a front part which carries the front end of the shaft (2) and a rear end which rotationally supports said movement take-up element;
• wherein the electric drive (30) and the electromagnetic clutch (220) are axially arranged between the front end (2a) of the shaft and said movement take-up element (223,223a).
