Abstract

See full text

A dual stage grinder pump (10) includes a housing (12) with a liquid inlet (20) and an outlet (26). An impeller (36) includes first impeller vanes (52) on a first axial side, and second impeller vanes (60) on a second axial side. A grinder (40) operates to reduce the size of suspended solids in the liquid that enters the pump inlet. Liquid passes from the inlet to a first fluid passage (30) and is acted upon by first vanes of the impeller in a first stage, and then passes through a second fluid passage (72). Liquid is acted upon by the second vanes of the impeller in a second stage and is passed through a third fluid passage (88) to the outlet.
