Abstract

856,706. Gear pumps. DE MICHELIS, R. March 4, 1959 [March 5, 1958; May 2, 1958], No. 7508/59. Class 110 (2). The pump, for pulverulent materials, comprises gears 19, 20 of flexible material on shafts 21, 22 which are coupled by external gearing 5, 6, 7 (Fig. 2, not shown). Cooling chambers 29, 30 may be provided. The material being pumped may be pressed into the inlet 23.
