A motor-pump assemblage for circulating a coolant through a system requiring heat transfer has a motor casing filled with liquid and mounted on the motor drive shaft a flywheel keyed to the shaft and a freewheeling shroud rotatable relative to the shaft and the flywheel. This shroud encompasses the flywheel but is spaced apart therefrom and includes passages for ingress and egress of liquid into the space between the flywheel and the shroud and out of this space. |
