FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to separating cup to be arranged in the gap between drive and driven parts of pump with magnetic coupling. Separating cup of the magnetic coupling consists of a flange, a shell and a bottom. Separating cup is a single solid part with a single-layer shell baked from fabric workpieces from composite materials with preliminary impregnation with furan resin and adding to the resin an anti-wear additive – tungsten carbide (WC) powder in any percentage ratio depending only on the degree of imparting anti-wear properties and condition of 100% impregnation of the fabric workpieces.
EFFECT: providing high strength of separating cups, ease of manufacture and absence of eddy currents, high wear resistance and chemical resistance, and their use in pumps with high content of abrasive and contaminants of various kinds in concentrated acids and alkalis.
