Bianco B42AV Technopolymer Automatic Multistage Submersible Pump for Treated Wastewater with Noryl Impeller

Confined tank installations and pressurized wastewater delivery are the primary focuses of this vertical float unit. It provides a reliable mechanism for supplying water to dripper bed systems where space for a traditional flexible float is unavailable. This variant is specifically designed for building services requiring pressurized clear or pre-treated water from subsurface collection points where space-saving is mandatory.

Operating performance is anchored by a 0.55 kW / 240v single-phase motor drawing a rated current of 4.0 Amps. The pump reaches a maximum head of 32 m and delivers an increased maximum flow of 105 L/Min compared to standard variants. The motor is rated for continuous duty, ensuring the pressure behavior remains stable during intensive irrigation and pressurized supply assignments.

Fluid transfer is conducted by a 3-stage hydraulic assembly utilizing Noryl impellers for high-head displacement. An 85mm elevated intake is integrated into the design to prevent the suction of sludge layers from the bottom of the tank. This configuration handles small particles up to 2mm while sustaining high volumetric efficiency through its precision multi-stage internals.

Structural integrity features a glass-filled Nylon hydraulic housing paired with a 410-grade stainless steel motor shaft for long-term durability. Motor safety is provided by dual mechanical seals in an oil bath and an auto-resetting thermal overload integrated into the Class F windings. The unit is supplied with a 10m power lead and a vertical fixed arm float switch to ensure reliable activation in restricted pits.

FEATURES

• Vertical fixed arm float switch facilitates automatic operation in narrow or restricted tank environments.
• Increased 105 L/Min flow rate supports high-volume delivery of treated residential wastewater.
• Multi-stage hydraulic assembly with 3 Noryl impellers provides the force needed for pressurized supply.
• Elevated 85mm intake prevents the pump from drawing in bottom-dwelling sludge and sediments.
• Slotted stainless steel strainer protects the hydraulic internals from algal and debris clogs.
• Dual mechanical seals in an oil bath ensure hermetic isolation of the asynchronous motor stator.
• Glass-filled Nylon construction provides a lightweight yet rugged housing for submerged service.
• Auto-resetting thermal overload prevents electrical damage during extended pressurized duty cycles.
