  • Patent number: 4321742
    Abstract: This invention relates to a wear lining containing rubber e.g. for pumps intended for handling wearing material such as dredger and mud pumps of the centrifugal type, which wear lining comprises a layer of wear rubber rigidly combined with a support plate. One of the problems with wear linings of such pumps is that already in manufacture they must be given a shape corresponding to the shape of the shell of the pump housing in which they are to be mounted, and must be manufactured in sections to permit mounting in their pump housing. For this a great number of moulds is required, which involves great costs of manufacture, and as the known wear linings for pumps are manufactured in sections, mounting thereof will be difficult and time-consuming, at the same time as there will be a joint between two sections, which has turned out to be a part of the wear lining that is exposed to wear.
