More Information
Summary:The disclosure provides a rotodynamic pump that resists clogging when pumping fluid that contains solid particles having a density that is greater than the fluid. The pump also includes a rotatable impeller assembly having at least one of a front shroud or a rear shroud that separates the pumping cavity from and defines with a casing at least one respective front cavity or rear cavity. The pump casing also has a primary passage between the pumping cavity and the discharge collector cavity, and at least one auxiliary passage connecting the discharge collector cavity and the at least one front cavity or rear cavity, wherein rotation of the rotatable impeller assembly causes the solid particles to move from the at least one front cavity or rear cavity radially outward to and through the at least one auxiliary passage to the discharge collector cavity.
