Abstract
A feeder apparatus for transferring particulate material and water from a sump outlet to the inlet of a pump is formed in the sump by making a well at the outlet of the sump and placing an impeller in the well. A partition is formed separating the inlet to the feeder from its outlet, the partition having a height equal to or exceeding that of the water level in the sump. The outlet from the sump is connected to a channel which has a continually decreasing cross-sectional area, the terminus of which is connected to the inlet of the pump. A fluid jet can be mounted at the inlet of the feeder for reducing the concentration of particulate fluids at the pump inlet or for fluidizing the particles at the entrance of the pump.
