GT Series pumps are designed to handle raw sewage, waste water and heavy duty industrial
applications where the pump is subject to clogging from over sized materials. Cutter pumps are
generally offered with vortex impeller. A cutting device and hard iron serrated casing cover
provided in the pump to cut the incoming materials into pieces, permitting smooth passage
through the pump into the discharge piping. A cutter pump’s job is also to reduce the size of the
solids. Cutter pumps are typically used to address clogs and rags.
