A shredder pump is a submersible wastewater pump designed to shear rags,
plastic bags and other solids that would clog an ordinary sewer ejector pump.
These pumps use a cutting impeller to whittle solids down to a consistency that
a wastewater system can easily handle.
Cutting action occurs only when solids are present, otherwise shredder pumps
operate like submersible sewage pumps.

Applications include sewage pump stations, septic systems, commercial and industrial sewage injector systems, hotels, construction sites and other applications requiring the reduction of difficult solids.
Shredder pumps are more common today than they were before plastics began to dominate the disposable consumer goods market.
In the past, most sanitary products were made of cotton and paper, which disintegrate in water and create little resistance when passing through a wastewater disposal system. Today, many of those products are made of plastics, which remain intact and stretch rather than tear when passing through a system, often creating a “net” that traps other debris.
If your sewage ejector system is subject to frequent clogging, you probably need a shredder pump. Today’s powerful shredders will grind down items ranging from cell phones to sneakers.
How To Select the Right Shredder Pump
When choosing a shredder pump it's important to consider the application it will be used in.
Submersible Shredder Pumps, also known as cutter pumps, will shear down problematic debris to a size most wastewater systems can process. They are designed for high flow, low head applications up to about 50 feet. For lower flow, high head conditions 50-150 feet, grinder pumps provide another option.
High Temperature Shredder Pumps will run in liquids that are too hot for conventionally built submersible pumps. High temperature shredders normally operate in temperatures between 140-200 °F. They are constructed of heat and corrosion-resistant materials and are a popular choice in process applications and those involving boiler blow-down.
Explosion-Proof Shredder Pumps are designed for use in combustible gas environments such as municipal and industrial wastewater facilities. They are constructed of durable, flame-resistant materials and contain motors super-reinforced to protect them from contact with liquids and abrasive materials.
