Abstract
A pulp feeder feeds the pulp from the pulp feeder housing to the pump impeller. The impeller is provided with vanes specially constructed to provide channels of sufficient dimension to permit the flow of the pulp through the channels. The impeller also has helical flights for feeding the pulp to the channels. The end of the pulp feeder is spaced close enough to the impeller to feed the pulp to the impeller flights but far enough away from the impeller to not interfere with the removal of air. An air removal pipe may also be included in the pulp feeder housing.
