DENOR Inline Sewage Grinder: Install Directly Into Your Existing Pipe, No Modifications Required.
Grind Inside the Pipe
Most sewage grinders require open channels or concrete works. The DENOR Inline Sewage Grinder is different—it integrates directly into your existing pipeline.

Ensure operational continuity with our Denor in-line channel sewage and wastewater grinder. Designed to protect your investment in downstream equipment, they employ a robust slow-speed, high-torque mechanism to shred and reduce solid matter.
Designed for municipal, commercial, and industrial applications, this sewage grinder installs inline with your piping system to shred solids before they reach sensitive equipment. No additional piping. No costly civil works.
The result: Continuous operation, protected pumps, and reduced maintenance.
Why Go Inline?
Built to Your Pipeline
Every pipeline is different. That's why the DENOR Inline Grinder is engineered for complete customization:
| Feature | Customization Options |
| Flanged Connections | Standard flanged in/out; dimensions customizable to match your pipe specs. |
| Grinding Components | Cutter type and configuration tailored to your solid waste profile. |
| Overall Dimensions | Size adjustable to fit unique spatial or flow capacity requirements. |
| Materials | Available in carbon steel or stainless steel configurations. |
How It Works?
1. Direct Pipeline Installation
Unlike channel grinders that sit in open flow, the inline grinder becomes part of your pipe. Wastewater flows directly through it.
2. Powerful Twin-Shaft Shredding
A robust slow-speed, high-torque mechanism (or cartridge cutter system) crushes solids—rags, wipes, plastics, wood, debris—into fine, manageable particles.
3. Straight-Through Flow
The design maintains a straight path for fluids and ground solids. No baffles, no redirection, no flow interference.
4. Clean Downstream
Pulverized material exits the grinder and continues through your pipes. Downstream equipment stays safe.
