In the dredging and mining industry, a pump isn’t just a purchase; it’s an investment in your project’s uptime. At TUSSU Pump, we’ve seen it all—from clogged intakes in Indonesia to seal failures in deep-sea operations.
To help you make an informed decision, we’ve compiled the 5 most frequent (and toughest) questions our technical team receives about the Tussu Pump series.
Q1: “My excavator is a CAT/Komatsu/Sany. How do I know your pump will actually fit my hydraulic system?”
The Reality: Compatibility is the #1 concern. You don’t want a “universal” pump that fits nothing perfectly.
The TUSSU Solution: We don’t just ship a pump; we ship a plug-and-play attachment. Our Tussu pumps come with custom Adapter Plates and hydraulic hose kits tailored to your specific excavator model. We match the pump’s required oil flow and pressure to your machine’s output, ensuring your hydraulic motor runs cool while delivering maximum torque to the agitator.
Q2: “What happens when I hit a layer of compacted clay or debris? Will the pump stall?”
The Reality: Standard suction pumps just “vacuum” the surface. If the material is hard, they suck water, not solids.
The TUSSU Solution: This is where the Tussu Agitator earns its keep. Made from 27% High-Chrome alloy, it’s designed to mechanically break down compacted layers. If you’re dealing with organic debris or roots, we offer an optional Cutter Version. It shreds fibrous material before it enters the impeller, preventing the “clog-and-stop” cycle that kills productivity.
Q3: “I need to dredge at 20+ meters depth. How do you prevent water from leaking into the hydraulic motor?”
The Reality: High external water pressure is the silent killer of seals.
The TUSSU Solution: Our deep-submergence units feature a Pressure-Balanced Sealing System. Unlike electric pumps that rely on air-filled housings, the Tussu hydraulic drive is naturally more resistant to depth. We use high-grade mechanical seals and an oil-compensation system that balances internal and external pressure, allowing for reliable operation even in deep-sea or deep-well dredging.
Q4: “How long do the wear parts actually last? I can’t afford to wait 4 weeks for a spare impeller.”
The Reality: Pumping slurry is like pumping liquid sandpaper. Wear is inevitable.
The TUSSU Solution: We cast our “Wet End” components (impeller, suction plate, agitator) with a hardness of 60-65 HRC. Depending on the abrasiveness of your material, our parts typically last 3-5 times longer than standard cast iron. More importantly, we maintain a stock of critical spares like the HTU series parts in our workshop, ready for fast international air-freight.
Q5: “Is it difficult for my operator to learn how to use it?”
The Reality: Complex equipment leads to user error and damage.
The TUSSU Solution: If your operator can run a bucket, they can run a Tussu pump. It’s controlled directly from the excavator’s cabin using the auxiliary hydraulic circuit. There are no complex electrical panels at the water’s edge. It’s a “hook it up and start pumping” system that reduces the need for specialized pump technicians on-site.
TUSSU Expert Tip:
When comparing quotes, don’t just look at the Discharge Diameter. Look at the Solid Handling Passage and the Chrome Percentage. A 6-inch pump that clogs every hour is far more expensive than an 8-inch pump that runs all day.
