    Detailing optimized internal fluid velocity paths, the Grundfos SEG.50.31.E.EX.2.50B establishes pure circulation stability. Grundfos SEG AUTOADAPT pumps are specifically designed for pressurized pumping of wastewater with discharge from toilets. This profound system streamlines liquid momentum throughout sanitary pipelines, actively preventing dangerous and sudden pressure drops.

    The heavy pumping mechanism features an aggressive grinder system that destructs incoming structural solids into small pieces, facilitating unobstructed evacuation sequences through restrictive diameter pathways. To preserve external cleanliness, the casing possesses a smooth surface that naturally prevents suspended organic dirt from permanently sticking.

    Precision engineered to generate immense propulsion, this industrial model reliably outputs 3.1 kW of sustained rotational power. Designed for commercial three-phase 415v infrastructures, the submerged unit commands an impressive maximum head of 23.8 meters and actively transfers a maximum flow of 516 L/Min. The assembly uses a sealed power plug connection.

    Setting an advanced standard for autonomous operations, the AUTOADAPT controller bypasses the requirement for external monitoring nodes. When multiple units operate in matching containment vessels, smart logic balances the workload. The power cable weaves thermal sensors directly into the motor windings for absolute heat protection.

    Features

    • Requires exactly 6.3 Amps of continuous rated current while actively grinding dense heavy biological solid waste.
    • Constructed incorporating secondary internal CER/CARNBR shaft sealing architecture for supreme mechanical liquid isolation.
    • Monitors critical operational sequences and absolutely refuses to start if the local electrical phase sequence is inverted.
    • Provides a formidable maximum operational internal structural fluid pressure resilience heavily exceeding 6 static bars.
    • Functions effectively within highly challenging fluid liquid boundaries securely reaching 40°C maximum limits.
    • Includes a versatile integrated alarm relay actively supporting both normally open and closed monitoring orientations.
