An impeller assembly having a housing supporting a rotatable impeller. The housing has a bottom entrance opening and a top exit opening separated by a curved back wall. A liner of low friction and abrasive resistant plastic material covers the inside of the back wall. The liner is removeably mounted on the housing so that it can be replaced without taking the housing apart. The impeller has a plurality of pivoted paddle assemblies. Each paddle assembly has a generally U-shaped liner of low friction and abrasion resistant material. The impeller is adjustably mounted on the housing to provide a minimum of clearance between the liner and the outer ends of the paddle assemblies as they rotate within the housing.
