Bianco B75VAS2-FF Cast Iron Non-Snag Submersible Drainage Pump for Drains with Semi-Open Impeller

Managing drain evacuation and managing large-scale pit dewatering is optimized with the high-capacity Bianco BIA-B75VAS2-FF. This automatic submersible pump utilizes a vertical fixed float to manage motion, ensuring reliable operation in confined spaces where traditional float switches would be prone to snagging. Its rugged construction excels in commercial and residential dewatering tasks, providing a professional solution for lifting septic wastewater and light slurries from deep collection sumps.

Reliable hydraulic performance is delivered by a powerful 0.75 kW / 240v single-phase motor drawing a rated current of 4.5 Amps. The pump achieves a maximum flow rate of 300 L/Min and reaches a maximum head of 10 m, providing the lifting capability required for heavy-duty drain management. The asynchronous motor is rated for continuous S1 duty when submerged, maintaining mechanical stability and thermal efficiency during prolonged high-volume dewatering cycles.

Hydraulic design is centered on a rugged cast iron semi-vortex impeller that facilitates the safe passage of solids up to 25 mm in diameter. This vortex configuration creates a centrifugal action that moves dirty water and non-abrasive particles away from the impeller blades, significantly reducing the risk of mechanical blockage. The 2-inch DN outlet ensures streamlined liquid transfer, maintaining high volumetric efficiency while processing wastewater containing sediments in large ditches or drains.

Mechanical construction features a heavy-duty cast iron hydraulic body paired with an industrial coating for superior corrosion resistance in submerged duty. A dual mechanical seal system isolates the internal electrical motor from the pumped media, while the Class B insulated assembly includes an in-built auto-resetting thermal overload. Rated for IP68 protection, the unit supports deployment in depths up to 5 metres with a 10m H07RN-F neoprene power lead for high chemical resistance.
