Bianco B45VAS2-FF Cast Iron Fixed Float Submersible Drainage Pump for Ponds with Semi-Open Impeller

Draining residential ponds and managing septic transfer in tight sumps is efficiently handled by the Bianco BIA-B45VAS2-FF. This automatic submersible pump features a vertical fixed float to manage motion, making it suitable for use in restricted situations where traditional flexible floats may encounter obstructions. Engineered for both portable emergency dewatering and fixed lifting stations, the unit provides a robust solution for homeowners requiring consistent evacuation of effluent during high-ingress events.

Driven by a 0.45 kW / 240v single-phase motor, this model draws a rated current of 3.7 Amps while sustaining high hydraulic performance. The system achieves a maximum flow rate of 200 L/Min and reaches a maximum head of 8.5 m, providing the pressure behavior necessary for deep-pit dewatering in residential wastewater systems. It is rated for continuous S1 duty when the motor is submerged, ensuring stable torque and low noise during intensive service cycles.

Hydraulic efficiency is centered on a single cast iron semi-vortex impeller that allows for the passage of suspended solids up to 25 mm in diameter. This configuration prevents mechanical clogs by creating a whirlpool effect that moves stringy materials and soft solids away from the impeller blades without direct contact. The 2-inch DN discharge ensures high-volume transfer, maintaining stable volumetric efficiency while processing dirty water in residential ponds or pits.

Structural durability is anchored by a rugged cast iron hydraulic body protected by an industrial-grade coating for long-term corrosion resistance. Internal protection features a dual mechanical seal system with an oil bath to isolate the electrical assembly from the pumped media. The Class B insulated motor includes an in-built auto-resetting thermal overload protector and is supplied with a 10m H07RN-F neoprene cable for secure immersion deployment up to 5 metres.

FEATURES

• Vertical 'fixed' float switch ensures reliable automatic operation in restricted or narrow sumps.
• Managed float motion significantly reduces the risk of snagging on pit walls or internal pipework.
• Cast iron semi-vortex impeller provides a 25 mm free passage for dirty water containing soft solids.
• Dual mechanical seals with an integrated lip seal provide redundant protection against liquid ingress.
• Rugged cast iron body with industrial grade coating ensures durability in abrasive wastewater.
• S1 continuous duty rated motor sustains high-torque performance during extended dewatering cycles.
• In-built auto-resetting thermal overload protector safeguards motor windings from over-temperature.
• 2" DN universal hose tail discharge facilitates high-volume liquid transfer with minimal friction loss.
