Abstract

Improvements in sewage pumps, especially in groups of submersible pumps in the means of transport, formed of an electric motor and a pump connected thereto, which has grinding facilities arranged in the area of the suction opening or connected to it, which comminute the aspirated additive mixtures, characterized in that, in combination with the grinding elements, fastening elements and/or reject deviators are provided, acting on the additional mixtures, which act antagonistically to the suction of the transport pump.
