Bianco B25VAS2-FF Cast Iron Compact Submersible Drainage Pump for Ditches with Semi-Open Impeller

Clearing ditches and managing drainage in restricted space pits is specialized for the Bianco BIA-B25VAS2-FF. This compact submersible pump incorporates a vertical float switch to manage float motion, ensuring reliable automatic operation in environments where traditional floats might snag. Its rugged design is ideal for residential dewatering and agricultural drainage where space is limited, providing consistent property protection during high-ingress events where dewatering is mandatory.

Hydraulic performance is provided by a 0.25 kW / 240v single-phase motor operating at a rated current of 1.8 Amps. Based on official technical data, this configuration delivers a maximum flow of 150 L/Min and reaches a maximum head of 7.5 m for efficient liquid evacuation from managed ditches. The asynchronous motor is rated for continuous S1 duty when submerged, ensuring stable performance and low operational noise during intensive residential dewatering cycles.

Clog-free operation is achieved through a single cast iron impeller designed to facilitate a 15 mm free passage for suspended particles. This hydraulic configuration is ideal for lifting clean or slightly contaminated water containing soft solids, as the semi-vortex action minimizes mechanical wear and internal contact. The 1¼-inch discharge with universal hose tail ensures streamlined liquid transfer, maintaining consistent volumetric efficiency even when processing wastewater with minor sediments.

Mechanical construction features a heavy-duty cast iron hydraulic body paired with an industrial-grade coating for superior durability. A dual mechanical seal arrangement prevents moisture ingress into the Class B insulated motor, while the AISI motor shaft offers high mechanical strength. Protection is completed by built-in thermal sensors and an IP68 enclosure rating, shielding the motor during submerged service in depths up to 5 metres in aggressive domestic environments.
