Abstract

724,353. Gear pumps. DEUTSCHE EDELSTAHLWERKE AKT.-GES. May 20, 1953 [May 23, 1952], No. 14195/53. Addition to 699,477. Class 110 (2). The pump according to the parent Specification is characterized in that the hard metal consists of chromium carbide and a relatively low-melting bonding metal. The latter may be nickel of from 5 to 60 per cent of the total composition and, in addition, chromium boride may be used. Various proportions are given in the Specification.
