The Rotorrake compact, non-clogging, single-shaft macerator from Boerger grinds coarse solids and stringy material to protect downstream equipment. It incorporates reversible flow direction and extraction of hard substances with throughput of up to 4,000 gpm. Solids-laden liquids are fed through rotating angled counter blades, where they are captured and chopped. Macerated solids flow with the liquid, and foreign materials accumulate in the debris collector. The unit can be used as a stand-alone machine, as a pump or with other peripheral machines. 844/263-7437; www.boerger.com.
