Bianco HSM750 Cast Iron Manual Submersible Dewatering Pump for Basements with Agitator Impeller

Automated oversight of subsurface pits and the evacuation of heavy drainage ingress are the primary focus of this high-head unit. It is engineered for industrial and residential sumps where abrasive-laden water must be shifted reliably to protect property or infrastructure. The inclusion of an automatic float switch ensures hands-free response to flood events, providing a professional defense against abrasive ingress.

Powered by a 0.75 kW / 240v single-phase motor, the assembly draws a rated current of 5.6 Amps to sustain high-pressure output. It achieves a maximum head of 18 m while attaining a maximum flow of 250 L/Min, based on verified technical specifications. The motor is designed for continuous S1 service, providing the thermal stability required for clearing deep pits during persistent rainfall or site flooding.

Fluid Handling is conducted by a semi-vortex urethane-coated impeller that creates the centrifugal action necessary for processing particles up to 10 mm x 25 mm. A specialized mechanical agitator is fitted to the intake to disturb settled solids, facilitating the movement of sediment-heavy fluids without clogging the hydraulic internals. The 3-inch discharge is bushed to a 2-inch DN hose tail for versatile high-volume transfer.

Structural integrity features a heavy-duty cast iron body and a 403-grade stainless steel motor shaft for enhanced durability in wet environments. Motor protection is provided by a dual mechanical seal arrangement in an oil bath and an IP68 enclosure rating for submergence up to 5 metres. The unit is supplied with a 10m H07RN-F neoprene lead, ensuring safe electrical connectivity in aggressive submerged conditions.

FEATURES

• Urethane-coated semi-vortex impeller delivers exceptional abrasion resistance in sand and silt dewatering tasks.
• Specialized mechanical agitator ensures that settled solids are disturbed and successfully moved through the body.
• Automatic float switch enables unattended operation and protects the motor windings from accidental dry-running.
• High-performance 0.75 kW motor achieves an 18m head for lifting fluids from deep subsurface collection pits.
• Rugged cast iron body and impact-resistant urethane strainer provide superior mechanical durability in site duty.
• Dual mechanical seals housed in an oil bath create a robust barrier against high-pressure liquid ingress.
• IP68 protection class supports safe deployment at practical submergence depths reaching 5 metres.
• 10m H07RN-F power lead provides secure connectivity and high resistance to oils and industrial chemicals.
