Abstract

Split ring seal for the closing of high pressure axes of boiler feed pumps, main or similar cooling medium pumps, composed of two slip rings, one of which rotates with the pump shaft, while the other it is fixed in an axially displaceable manner in the pump housing and can be approximated by the sliding ring in rotation, characterized in that the sliding rings (4,5) are mounted on the shaft sleeve (3) and on the housing (2) without contact, that is to say in a floating manner, each of them being centered by a joint (11) of circular section, at the same time, that a drive device, for example at least one cylindrical spike (10), is it handles the transmission of the moment of rotation on one side (sliding ring 4) and the support on the housing (sliding ring 5), on the other, and by the fact of anus one of the closing surfaces (18) is composed of a flat surface (19) located in the vicinity from the center of the shaft and radially possessing a joint groove that increases progressively and forms a transition (20).
