Abstract
A vertical pump for transferring a dispersion of solids in a liquid comprising an upper chamber for receiving the dispersion; an intermediate chamber in fluid communication with the upper chamber and including an outlet nozzle for discharging the dispersion; and a lower chamber in fluid communication with the intermediate chamber and including an impeller for inducing a vortex in the intermediate chamber. The dispersion is discharged from the outlet nozzle without deleteriously affecting the solids of the dispersion thereby transferring the dispersion independently of direct contact with the impeller. Generally, the solids are a friable sorbent, such as active carbon, and this pump can be used in combination with a screening apparatus which separates the solids from another liquid prior to delivering the solids to the upper chamber of the pump for forming the dispersion therein.
