Impellers 1 and 2 rotate about fixed axes A and B and have symmetrically arranged teeth c and d and tooth spaces e. When impellers 1 and 2 rotate, fluid is continuously delivered in the direction of arrows a and b. The suction and discharge chambers are separated by imparting special profiles to teeth c and d and to tooth spaces e of the impellers. The impellers are driven by two meshing identical gears keyed to the shafts of impellers 1 and 2.
