At Tussu Pump, we understand that moving water is easy—but moving “liquid sandpaper” is where most pumps fail. Our KBD Series Submersible Slurry Pumps are specifically engineered for the most punishing environments: sand pits, bentonite recycling, and mineral processing.
Equipped with a high-chrome iron agitator, Tussu KBD pumps don’t just wait for solids to enter—they actively stir up settled sediment to ensure a smooth, continuous flow of high-density slurry.
Real-World Success: Tussu KBD Series in Action
Case Study 1: River Sand Dredging & Reclamation (Southeast Asia)
-
The Challenge: A land reclamation project required the removal of heavy river silt and sand. Standard dewatering pumps were wearing out their impellers in less than 200 hours, and the suction inlets were constantly clogging with settled mud.
-
The Tussu Solution: We deployed the Tussu KBD415 (15kW) slurry pump.
-
The Result: The integrated agitator successfully liquefied the settled sand, allowing it to be pumped at a steady concentration. The 27% High-Chrome (Cr27) alloy construction extended the wear life by 400% compared to the client’s previous cast iron pumps, dramatically reducing their cost per cubic meter of material moved.
Case Study 2: Bentonite Management for Tunnel Boring (Middle East)
-
The Challenge: During a deep tunnel excavation, the slurry separation plant struggled with a buildup of thick bentonite clay in the settling tanks. The fluid was too viscous for standard drainage pumps to handle.
-
The Tussu Solution: A fleet of Tussu KBD37.5 (7.5kW) and KBD411 (11kW) pumps was installed.
-
The Result: Tussu KBD pumps provided the necessary torque to break up the clay. The slimline top-discharge design also allowed the pumps to fit into narrow sump pits, ensuring the tunnel face stayed clear of excess slurry and preventing project delays.
Engineering the “Tussu Tough” KBD Advantage
Why do engineers specify the Tussu KBD Series for slurry management?
-
Built-in Agitator Technology: Our agitator breaks up settled solids into a suspension, preventing suction blockages and allowing the pump to handle higher percentages of solids by weight.
-
Unmatched Wear Resistance: The impeller, suction plate, and agitator are all manufactured from High-Chrome iron. This is not just a coating; it is solid, wear-resistant metallurgy designed for long-term immersion in abrasive grit.
-
Four-Pole Motor Performance: Unlike high-speed drainage pumps, the Tussu KBD utilizes a 4-pole motor (approx. 1450/1750 RPM). This lower speed reduces internal wear and provides the high torque needed to move viscous fluids.
-
The Tussu Interchangeability Promise: As with all our series, KBD spare parts (volutes, impellers, and seals) are 100% interchangeable with international industry standards, ensuring your project is never stalled by a lack of parts.
