Repeated pump clogs ruin lift stations, trigger costly overflow cleanups, and waste maintenance hours. Modern wastewater streams carry tough debris—flushable wipes, sanitary items, shop rags, and stringy materials—that jam standard sewage ejector pumps.
The Tussu® Non-Clogging Submersible Grinder Pump solves ragging and clogging at the source. Engineered with a high-torque cutter system, this heavy-duty submersible pump shreds solids into fine slurry before they enter the discharge line, ensuring smooth flow through small-diameter piping.
Why Choose the Tussu® Non-Clogging Grinder System?
-
Heavy-Duty Cutting Mechanism: Hardened stainless steel cutter blades deliver thousands of slices per minute, handling tough solids, plastics, textiles, and organic waste without binding.
-
Anti-Clogging Impeller Design: Semi-open, high-efficiency impeller prevents debris wrapping and reduces wear on the hydraulic end.
-
High-Head & Long-Distance Pumping: Generates the head pressure required to push wastewater uphill or across long distances to municipal sewer mains or septic tanks.
-
Dual Mechanical Shaft Seals: Silicon carbide oil-lubricated seals protect the motor chamber from moisture ingress, extending operational lifespan.
-
Thermal & Overload Protection: Built-in auto-reset thermal sensors protect the motor windings during dry runs or severe voltage fluctuations.

Where Tussu® Grinder Pumps Excel
-
Commercial Buildings & Restaurants: Handles high-volume grease traps, food waste, and public restroom usage.
-
Residential Sewage Lift Stations: Ideal for basements, low-lying properties, and pressure sewer networks.
-
Industrial Wastewater Treatment: Processes manufacturing washdown, fibrous slurry, and processing plant effluent.
-
Municipal & RV Dump Stations: Manages unpredictable public waste streams without constant maintenance calls.
Grinder Pump vs. Standard Sewage Ejector Pump
Standard sewage ejector pumps pass solids whole through large-diameter pipes (typically 2” or larger). If your system uses small-diameter discharge lines (1.25” to 2”) or faces high head friction, a standard pump will fail or clog frequently.
The Tussu® Submersible Grinder Pump pulverizes solids into microscopic particles, allowing wastewater to pump easily through long, narrow pipe runs without pressure loss or pipe wall buildup.
Installation & Maintenance Tips
-
Verify Line Pressure: Match pump shut-off head against static elevation and friction loss.
-
Control Panel Setup: Pair with a float switch control panel featuring high-water alarm and alternator functionality for duplex systems.
-
Routine Inspection: Inspect cutter clearances every 12 to 18 months in high-solids commercial applications.
