The primary difference between the Tussu® KBZ and Tussu® KBZE submersible drainage pumps comes down to operation and automation: the KBZ is a manual, continuous-run heavy-duty dewatering pump, while the KBZE is an intelligent automatic submersible pump equipped with an integrated electrode level sensor.
Both models share identical heavy-duty cast-iron bodies, top-discharge flow jackets, and wear-resistant hydraulic components built for tough construction, quarry, and mining applications.
KBZ vs. KBZE: Feature Comparison
| Feature | Tussu® KBZ Series | Tussu® KBZE Intelligent Series |
| Control System | Manual switch or external control panel | Integrated electric sensor probe (electrode) |
| Operation | Continuous running until manually powered down | Auto start when water touches probe; auto stop within 60s when water drops |
| Motor Safeguards | Standard thermal protection | Built-in protection against dry-running, overload, phase loss, and reverse rotation |
| Wiring & Setup | Requires external floats or starter box wiring | Plug-and-play design with no extra panel needed |
| Energy Consumption | Standard (runs constantly if unmonitored) | Optimized (reduces power costs by cycling only as needed) |
| Power Range | Wide range (up to 15 kW / 20 HP) | Compact power range (1.5 kW / 2 HP to 5.5 kW / 7.5 HP) |
Shared Engineering Features
-
Abrasive-Resistant Hydraulics: Both pumps use high-chrome alloy semi-open impellers and ductile iron wear plates (hardness $\ge 58$ HRC) to pump dirty water containing sand, silt, and grit without rapid wear.
-
Top-Discharge Cooling Jacket: Water flows around the motor casing before exiting the discharge outlet, keeping the motor cool even during low-water dewatering.
-
Dual-Performance Conversion: Easily convert between high-head (deep lift) and high-volume (max flow up to 105 m³/h) by swapping the impeller, suction cover, and hose coupling.
Selection Guide
-
Select the Tussu® KBZ if you run continuously monitored 24/7 site dewatering, already connect your pumps to central site control boxes, or require high-horsepower motors above 5.5 kW.
-
Select the Tussu® KBZE for unattended sumps, basement pits, or variable inflow areas where automatic dry-running protection prevents motor burnout and saves electricity.
