JWCE’s Family of Pump Station Solutions:
Muffin Monster in-channel model 30005 - This legendary sewage grinder has the power to tear through the toughest solids. The dual shafted grinder turns rags, plastics, leaves, branches, clothing and debris into small particles that flow easily through pumps and systems.
The Muffin Monster easily installs in gravity fed sewer lines almost anywhere – and we mean anywhere – on the wall of a pump station, in a deep channel or in a dedicated grinder manhole. The grinder uses an incredibly efficient 3 or 5-hp (2.2 or 3.7 kW) motor and generates a ton of cutting force at peak loads.
Grinders are installed upstream of the pump.
Options: 7, 11 or 13-tooth cutters; extra hard cutters; stainless steel cutters; an exclusive JWCE immersible motor; custom made stainless steel guide rails and sub-channel (for support and retrieval); overflow screening bars; lifting bails; lifting chain; service plans; pre-fab manhole installations.
Applications: municipal lift stations, industrial, highway rest areas, court houses, jails, nursing homes, hospitals, institutions, shopping malls, casinos, resorts
Installation configurations: Channel installation; wall mounted in wet well pump stations; New pre-fab manhole installation
Muffin Monster in-line model 30004T – The in-line version of the Muffin Monster is a powerful grinder and fits in 4, 6, 8, 10 or 12″ (100, 150, 200, 250 or 300 mm) pipeline sizes. It shreds the rags and debris into small pieces in order to protect pumps and pipelines.
This wastewater grinder can fit almost anywhere – underground, on the ceiling, upside down, in a closet or just about anywhere you need to grind solids and debris to keep the wastewater flowing smoothly.
In-line Muffin Monsters are installed anywhere upstream of the pump and can even be installed right in front of the pump’s inlet. Wastewater can flow through the grinder via gravity or via pump suction.
Options: 7 , 11 or 13-tooth cutters; extra hard cutters; stainless steel cutters; an exclusive JWC immersible motor; service plans
Applications: municipal lift stations, industrial, court houses, jails, nursing homes, hospitals, institutions, shopping malls, casinos, resorts

Macho Monster in-channel model 40002 – This is the Muffin Monster’s bigger brother and has the power to grind up the toughest and biggest flows of debris. The Macho Monster is a good choice for large jails and prisons where heavy flows of debris can be frequent – or for pump stations with extremely heavy ragging and clogging issues.
This wastewaste grinder uses an energy efficient 10-hp (7.5 kW) motor to crunch on debris and protect the sewer pumps. When you’ve got a big sewer clogging problem – the big Macho Monster grinder is the solution.
Options: extra hard cutters; an exclusive JWC immersible motor; stainless steel guide rails and sub-channel (for support and retrieval); overflow screening bars; lifting bails; lifting chain; service plans; pre-fab manhole installations (by others).
Applications: municipal lift stations with heavy flows of debris, large jails, prisons, large hospitals
Installation configurations: Wall mounted in wet well pump stations; channels; vaults; manhole installation
Macho Monster in-line model 40002 – The Macho Monster can also fit into pipelines including 12, 16, 18 and 20″ (300, 400, 450 and 500mm). This heavy-duty grinder is great for jails, prisons and large municipal dry-well lift station installations.
The Macho Monster can be installed right in front of the pump and can handle flows of wastewater 1.8-mgd (284 m3/h) and up. The grinder prevents ragging and clogging and protects pumps from damage.
On gravity fed sewer pipelines the Macho Monster in-line easily installs in an underground vault with a bypass pipeline. Our sewage grinders work just fine with non-pressurized gravity flow or in pressurize pipelines.
Options: extra hard cutters; an exclusive JWC immersible motor; service plans
Applications: municipal lift stations, large jails, prisons, large hospitals
Installation configurations: Dry well lift stations or underground vaults
Channel 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
