Bianco HSM500 Cast Iron Manual Submersible Dewatering Pump for Storm Water with Agitator Impeller

Effective construction site dewatering and the evacuation of abrasive pit water are the core roles for this agitator-equipped unit. It targets demanding environments where silt-heavy storm water must be shifted to prevent project delays or structural damage. The automatic float switch enables the system to react instantly to rising ingress levels in subsurface collection pits without requiring constant operator supervision.

Hydraulic output is driven by a 0.5 kW / 240v single-phase motor that attains a maximum head of 12 m. Drawing a rated current of 2.8 Amps, the assembly achieves a maximum flow of 210 L/Min, providing the lifting force necessary for deep pit drainage. The Class F insulated motor is rated for continuous S1 duty, maintaining thermal stability and torque consistency during intensive service cycles in harsh ground water conditions.

Superior solids handling is achieved through a semi-vortex urethane-coated impeller paired with a specialized mechanical agitator. The agitator disturbs settled sediments, allowing the pump to process abrasive particles and debris up to 10 mm x 25 mm without clogging the hydraulic internals. This configuration significantly reduces wear on the internal blades, extending the service life when handling sand-laden ground water and silt.

Structural durability is anchored by a rugged cast iron hydraulic housing protected by an industrial-grade coating for corrosion resistance. Internal protection utilizes a dual mechanical seal system housed in an oil bath to isolate the motor from fluid ingress. The unit is IP68 rated for practical submergence up to 5 metres and is supplied with a 10m H07RN-F neoprene power lead for secure connectivity in demanding industrial settings.

FEATURES
