Bianco B45VAS2 Cast Iron Automatic Submersible Drainage Pump for Septic Transfer with Semi-Open Impeller

Protecting septic systems and managing site dewatering tasks is efficiently handled by the high-capacity Bianco BIA-B45VAS2. This automatic submersible drainage pump is specialized for lifting septic wastewater and managing sump emptying in residential and light industrial environments. Engineered for both portable emergency use and fixed lifting stations, the unit provides a robust solution for homeowners requiring consistent evacuation of contaminated fluids during high-ingress events.

Driven by a 0.45 kW / 240v single-phase motor, this model draws 3.7 Amps while sustaining high hydraulic displacement. The system achieves a maximum flow of 200 L/Min and reaches a maximum head of 8.5 m, providing the lifting force necessary for deeper residential tanks. It is rated for continuous S1 duty when submerged, utilizing oversized components to ensure stable operation and low mechanical noise during intensive pit dewatering cycles.

Operational reliability is enhanced by a cast iron semi-vortex impeller that allows for the passage of solids up to 25 mm in diameter. This design minimizes the risk of mechanical clogs by allowing dirty water containing stringy materials to move through the hydraulic body without direct contact with the impeller blades. The 2-inch BSPF discharge port facilitates streamlined liquid evacuation, maintaining high volumetric efficiency even when processing wastewater containing larger sediments.

Mechanical durability is anchored by a rugged cast iron hydraulic body paired with an industrial-grade coating for resistance to abrasive particles. Internal protection features a dual mechanical seal system and lip seal to safeguard the Class B insulated motor from liquid ingress. The unit is rated for IP68 protection with a maximum immersion depth of 5 metres, featuring an integrated auto-resetting thermal overload to protect the windings during heavy service in septic pits.

FEATURES

• High-displacement 200 L/Min flow rate supports rapid liquid evacuation in residential septic systems.
• Cast iron semi-vortex impeller facilitates a 25 mm free passage for dirty water containing soft solids.
• Automatic flexible float switch provides reliable hands-free water level management in collection tanks.
• Dual mechanical seals with an additional lip seal ensure superior motor protection in submerged duty.
• Rugged cast iron hydraulic body with industrial coating resists abrasion in contaminated wastewater.
• S1 continuous duty motor rating supports indefinite operation when the pump is completely immersed.
• Integrated auto-resetting thermal overload protector prevents electrical damage from over-temperature.
• Large 2" BSPF discharge port enables high-volume transfer with reduced friction loss in drainage lines.
