    Agricultural supply and large-scale residential distribution benefit from this submersible pump's groundwater recovery capabilities from 4-inch wells. It processes clean water containing sand up to 150 g/m³ and supports continuous operational cycles for pressurised irrigation networks.

    With a 0.55 kW three-phase motor at 415V, the 10-stage unit delivers a maximum head of 64 meters at a flow rate of 50 L/Min. The motor coupling conforms to NEMA standards, providing a standardised mechanical connection for simplified maintenance.

    Within each stage, LEXAN floating impellers can move axially against polycarbonate diffusers, helping to prevent sand particles from jamming the rotating assembly. This design contributes to extended service life in deep-well applications where sediment is present.

    AISI 304 stainless steel forms the external jacket, with a chrome-nickel steel delivery casing incorporating a built-in non-return valve. This valve shields the hydraulic stages from back-pressure and reverse rotation caused by the water column. Rated for liquid temperatures up to 35°C, the assembly features Class F motor insulation and a chrome-nickel steel suction filter.

    FEATURES

    • Radial floating impellers accommodate sand passage while reducing mechanical blockage risk
    • Reinforced polycarbonate diffusers enhance fluid velocity and reduce operational energy requirements
    • Ten-stage hydraulic assembly delivers 64 meters of head for rural water supply and irrigation applications
    • AISI 304 stainless steel external jacket provides resistance to mineral corrosion and structural deformation
    • Built-in non-return valve eliminates the need for external check valves and prevents motor damage from backflow
    • NEMA-standard coupling simplifies field installation and ensures compatibility with a wide range of submersible motors
    • Chrome-nickel steel suction lantern and filter provide a barrier against oversized mineral debris
    • Class F motor insulation and IP68 protection support reliable performance under continuous immersion
