Bianco HSA750 Cast Iron Automatic Submersible Dewatering Pump for Pits with Agitator Impeller

Manual dewatering of storm water from construction footings and basement collection sumps is the primary utility for this abrasive-resistant unit. It provides site operators with complete control during precision water removal tasks where high sediment content is expected in the fluid stream. The portable design makes it an ideal tool for rapid mobile deployment across diverse building projects requiring immediate area clearance.

Delivering consistent hydraulic performance, the 0.5 kW / 240v motor operates at a rated current of 2.8 Amps. It reaches a maximum head of 12 m and achieves a maximum flow rate of 210 L/Min, ensuring efficient liquid displacement from subsurface collection points. The asynchronous motor supports S1 continuous operation, maintaining torque stability and low mechanical noise during intensive pit clearing tasks in industrial settings.

Liquid intake is optimized for abrasive environments, utilizing a specialized semi-vortex impeller designed to process particles up to 10 mm x 25 mm. A mechanical agitator is integrated into the intake to prevent sediment settlement, ensuring that silt and sand remain in suspension for effective evacuation. This design minimizes internal contact and mechanical fatigue, sustaining high volumetric efficiency when processing contaminated ingress.

Mechanical durability is anchored by a heavy-duty cast iron hydraulic body protected by an industrial-grade coating. Redundant motor protection features an in-built auto-resetting thermal overload and Class F insulation to safeguard the stator from over-temperature failure during prolonged use. The unit is rated for IP68 protection and can safely be immersed to depths of 5 metres during demanding manual dewatering applications.

FEATURES

• Mechanical agitator prevents sediment buildup at the intake by keeping abrasive sand and silt in suspension.
• Semi-vortex impeller with urethane coating offers superior resistance to wear from grit and abrasive site debris.
• Manual operation mode provides precision control for specific pit clearing or floor dewatering assignments.
• Rugged cast iron construction with industrial grade coating protects against impact and corrosive fluid ingress.
• Redundant motor safety features include a built-in auto-resetting thermal overload for winding protection.
