A macerator is disclosed which has an impeller which on its upstream side is provided with radial fins adjacent fixed teeth and through which a number of slots pass. On its downstream side an outwardly flared member is provided with radial vanes. Effluent entering the macerator is thrown by the fins onto the teeth and can than pass through the slots to be thrown outwardly by the member and then to the macerator outlet. The provision of the member provides a significant pumping effect.
