    Large-scale water management projects and industrial pressure boosting require pumps that deliver high heads with exceptional reliability. The Lowara ZN646/15-3N features a 6-inch wet end with 6-inch motor and NEMA coupling, delivering 1000 L/Min at 153.2 metres of shut-off head for demanding applications. The hydraulic stages ensure stable performance across varying demand conditions.

    Every wetted component is fabricated from AISI 316 stainless steel, providing long-term corrosion resistance in aggressive groundwater environments. The impeller and diffuser arrangement includes a removable wear ring for maintenance convenience, while the integrated non-return valve prevents water column reversal. The suction strainer limits sand ingress to 100 grams per cubic metre, protecting internal clearances.

    Powered by an 18.5 kW three-phase motor at 415V, the pump draws 38.5 Amps and achieves 153.2 metres of shut-off head. Flow capacity is 1000 L/Min through the 80 mm discharge outlet. Performance testing to EN ISO 9906 Grade 3B ensures reliable operation across the full duty range.

    Submersion depths up to 350 metres are supported by Class F insulation and IP68 protection. The Duplex stainless steel shaft provides mechanical strength for continuous operation, while AISI 316L tie rods offer additional structural support. NEMA motor compatibility simplifies assembly, and safety hook holes facilitate installation.
