Bianco B18VAS2-FF Cast Iron Vertical Float Submersible Drainage Pump for Cellars with Semi-Open Impeller

Dewatering cellars and managing water removal in confined residential pits is optimized with the Bianco BIA-B18VAS2-FF. This automatic submersible pump features a specialized vertical float switch designed to manage float motion, significantly reducing the risk of snagging in tight installations. Its compact construction excels in domestic building services where space is limited, providing a dependable solution for lifting clean or slightly contaminated water from subsurface sumps.

Reliable hydraulic performance is delivered by a 0.18 kW / 240v single-phase motor drawing a rated current of 1.6 Amps. The pump achieves a maximum flow rate of 133 L/Min and reaches a maximum head of 7 m, providing efficient lifting capability for cellar dewatering systems. The asynchronous motor is rated for continuous S1 duty when fully submerged, ensuring operational stability during prolonged dewatering cycles when managing consistent fluid ingress.

Efficient liquid handling is achieved through a single cast iron semi-vortex impeller designed to process wastewater containing suspended solids. The hydraulic configuration facilitates a free passage of 15 mm, allowing non-abrasive particles and some stringy materials to pass through the pump body with a reduced risk of blockage. This vortex design creates a centrifugal effect that moves solids away from the impeller blades, supporting dependable operation in residential sumps.

Mechanical durability is provided by a rugged cast iron hydraulic body combined with an industrial-grade coating for long-term corrosion resistance. Internal protection features a dual mechanical seal system and lip seal to isolate the motor from the pumped media, while the Class B insulated assembly includes an in-built auto-resetting thermal overload. The unit is rated for IP68 protection, supporting deep-immersion deployment up to 5 metres in confined pits and cellars.
