Abstract: A method of forming a cutter head with an axis of rotation comprises forming a hub; forming at least one ring with integral cutter body arm segments extending from the at least one ring; and connecting the hub to the cutter body arm segments so that the hub and the at least one ring are connected and around the axis of rotation.

Abstract: A pump and submersible solids processing arrangement includes a pump, having a suction inlet and discharge, and a submersible solids processing arrangement positioned in fluid communication with the suction inlet of the pump and being structured to macerate larger solids and matter that is entrained in a fluid to thereby reduce the size of the solids prior to entry of the fluid and solids into the inlet of the pump, the arrangement further including macerating members the speed and arrangement of which are selectively determinable or adjustable, and the arrangement further comprising an agitator arrangement for directing solids into the submersible solids processing arrangement.
