    Lowering long-term operating costs while maximizing safety containment, the SL1.85.100.100.4.52H.N.51D.A.T provides immense value to intensive municipal sectors. Combining a 150 mm inlet with a 100 mm outlet, this asset is specifically built to extract vast fluid quantities from raw water intake stations and industrial processing zones.

    The structural casting accommodates a highly advanced S-Tube impeller that dictates an 85 mm free passage. This vastly widened clearance neutralizes the severe blockage risks historically tied to solid-heavy sewage environments. Engineers can confidently rely on continuous processing efficiency without the threat of manual unblocking.

    Energy is supplied by a highly refined 10 kW continuous-duty Grundfos motor running on a 415v three-phase grid. This 4-pole system delivers a maximum head of approximately 19 m alongside an incredible 4986 L/Min flow. The resulting operational stability maintains low vibration signatures, keeping the motor cool during harsh deployment.

    Removing dependency on external safeguards, the unit natively features responsive moisture sensors and active motor-protection thermistors. These systems continually verify sealed cavity integrity, reacting instantly if excessive heat or liquid compromises internal boundaries, saving commercial facilities from catastrophic replacements.

    Features

    • Integrates a state-of-the-art cable entry plug that allows the fifteen-meter electrical line to be detached safely and efficiently without opening the main motor housing.
    • Features an innovative double shaft seal configured inside a dedicated cartridge assembly, minimizing service downtime during rigorous scheduled municipal maintenance.
    • Utilizes a high-strength secondary shaft sealing ring built from a resilient silicon carbide and carbon friction composition to actively block internal contamination.
    • Manufactured with a thick primary casting built entirely from EN 1561 EN-GJL-250 iron, delivering maximum environmental durability across flooded operations.
    • Engineered to function continuously through heavy-density liquid temperatures between ten and forty degrees Celsius within permanent subterranean pump stations.
    • Designed to safely process deep fluid extraction at a maximum installation depth of twenty meters while preserving an exact eight bar operating pressure boundary.
