    Dewatering tight pits, balconies, or narrow drainage sumps is the specialized focus of this internal-float unit. Its compact footprint and vertical activation mechanism allow it to operate in restricted locations where traditional flexible floats would encounter obstructions. The top discharge configuration further enhances its suitability for installation in limited-clearance residential environments where space-saving dewatering is a necessity.

    Powered by a 0.45 kW / 240v single-phase motor, the unit draws a rated current of 1.51 Amps during operation. It achieves a maximum head of 6.3 m and delivers a maximum flow of 135 L/Min for efficient water removal from subsurface areas. The motor is engineered for S1 continuous duty, providing the thermal stability required for extended service cycles when clearing consistent fluid ingress in domestic basements.

    Hydraulic efficiency is geared toward complete area clearing, with the ability to pump water levels down to below 5 mm from the floor. It handles small particles up to 1 mm in diameter through a single impeller design that minimizes mechanical fatigue and sustains stable volumetric transfer. This precision suction capability makes the pump a superior choice for garage floor drying or clearing shallow floor ingress where standard pumps fail.

    Structural durability is provided by a 20% glass-reinforced polypropylene hydraulic body and inlet strainer for enhanced impact resistance. Internal protection utilizes a reliable lip seal arrangement to isolate the electrical stator from the pumped media while maintaining high mechanical efficiency. The Class B insulated motor includes an auto-resetting thermal overload protector and is rated for IPX8 submersion in depths up to 3 metres.

    FEATURES

    • Internal float mechanism allows for automatic operation in narrow pits where flexible floats cannot move.
    • Low-draught suction capability enables the unit to clear water levels down to below 5mm from the surface.
    • Compact top discharge design facilitates installation in restricted space residential and commercial sumps.
    • 20% glass-reinforced polypropylene construction provides high structural strength and chemical resistance.
    • Auto-resetting thermal overload protector safeguards the motor windings from accidental over-temperature.
    • Continuous S1 duty asynchronous motor sustains performance during intensive drainage and floor drying.
    • IPX8 rated enclosure ensures safe electrical isolation during submerged deployment up to 3 metres.
    • Precision hydraulic design facilitates the transfer of water containing fine particles up to 1mm.
