Channel Monster grinderChannel Monster models CMD or CDD – The industry’s high-flow sewage grinder of choice is JWC’s patented Channel Monster. This innovative and powerful grinder comes in various sizes and can process nearly 60-million gallons per day (9300 m3/h). It grinds all of the wastewater rags and debris into small particles so they easily pass through pumps and pipes.

The Channel Monster is gravity fed and particularly helpful in very large pump stations where high-flows are expected and wastewater pumps must be protected from ragging.

The larger Channel Monster grinders over 40″ (1,000-mm)  use much thicker drive shafts, larger cutters and bigger housings to ensure maximum power in all flow conditions. Over 4,000 Channel Monsters have been installed worldwide in wastewater systems and pump stations – helping to keep sewage flowing 24/7.

Options: one screen drum (CMD) or two (CDD); extra hard cutters; our exclusive JWC immersible motor;  stainless steel guide rails; stainless steel overflow bar racks; service plans

Applications: pump stations

Installation configurations: in any wastewater channel – wide, deep or narrow
