Bianco KT215 Cast Iron Hi-Chrome Submersible Dewatering Pump for Building Sites with Open Impeller

Manual evacuation of abrasive groundwater from basements and site collection pits is streamlined with this robust dewatering unit. It targets environments where high-head performance is required to lift sediment-laden storm water from deep subsurface areas or flooded footings. The manual operation mode gives site personnel complete control during specialized cleanup tasks where the removal of abrasive contaminants is a priority.

Operational output is defined by a 0.75 kW / 240v asynchronous motor that attains a maximum head of 18 m. Drawing a rated current of 5.6 Amps, the system achieves a substantial maximum flow of 250 L/Min for rapid liquid displacement from collection tanks. The internal motor is engineered to maintain high torque and stable pressure behavior, providing the lifting force necessary for consistent clearance of deep pits or flooded floors.

Liquid transfer utilizes a semi-vortex hydraulic configuration capable of processing soft solids and abrasive particles up to 10 mm x 25 mm. A mechanical agitator is fitted to keep sand and silt in suspension, significantly lowering the risk of mechanical clogs or internal wear during active dewatering. This design is optimized for fluids between 2°C and 35°C, sustaining flow efficiency in abrasive storm water collection sumps.

Construction features a 403-grade stainless steel motor shaft and a hermetically sealed cast iron body for long-term durability in submerged duty. Protection against moisture ingress is maintained by a dual mechanical seal arrangement in an oil bath and an IP68 rating for submergence up to 5 metres. An auto-resetting thermal overload is integrated into the Class F windings to protect the system from accidental overheating failure.
