Bianco B75VAS2 Cast Iron Automatic Submersible Drainage Pump for Light Slurries with Semi-Open Impeller

High-volume greywater pump out and agricultural irrigation tasks are reliably managed with the Bianco BIA-B75VAS2. This automatic submersible drainage pump is specialized for septic transfer and the pumping of light slurries in commercial and domestic building services. Its rugged redesign prioritizes structural resistance and high-volume evacuation, ensuring consistent property protection during heavy rain events where large volumes of liquid ingress must be managed effectively.

Providing powerful hydraulic performance, the 0.75 kW / 240v single-phase motor operates at a rated current of 4.5 Amps. This configuration delivers a maximum flow of 300 L/Min and reaches a maximum head of 10 m for efficient liquid evacuation from large-scale collection pits. The asynchronous motor is rated for continuous S1 operation when fully submerged, providing the thermal stability required for intensive dewatering tasks in septic wastewater systems.

Hydraulic efficiency is centered on a heavy-duty cast iron semi-vortex impeller designed to facilitate the safe passage of solids up to 25 mm. This vortex configuration prevents clogging by creating a centrifugal action that moves stringy materials and non-abrasive particles away from the impeller blades. The 2-inch discharge supports high-volume transfer, maintaining stable volumetric efficiency while processing dirty water containing suspended solids in septic sumps.

Structural integrity is ensured through a rugged cast iron hydraulic body paired with an industrial-grade coating for superior corrosion resistance. Internal protection features a dual mechanical seal system that isolates the electrical assembly from the pumped media, while the AISI motor shaft provides high mechanical fatigue strength. The unit is rated for IP68 protection and includes integrated thermal sensors to safeguard the Class B insulated motor against over-temperature failure.
