    Corrosive, chemically active municipal supply loops benefit from the resilient construction of this multistage unit. The assembly functions effectively within varied fluid handling environments, providing consistent pressure for process cooling, water treatment, or small-scale commercial filtration systems. By utilizing high-grade materials, the pump maintains structural integrity when exposed to demanding chemical concentrations often found in process water management.

    Operational threshold limits are defined by a Max Head of 63.6 m alongside a Max Flow of 40 L/Min. Powering these metrics is a 0.77 kW single-phase motor, which operates at a current draw of 3.82 Amps. This specific hydraulic configuration ensures that laminar flow remains stable even when subjected to varying system resistances, enabling precise control over liquid circulation within closed or open piping networks.

    Fluid dynamics are governed by a multistage impeller arrangement crafted from AISI 316L stainless steel, designed to maximize kinetic energy conversion across each stage. The internal geometry supports high-pressure output while minimizing turbulent losses, ensuring that the velocity profile remains uniform from the 25 mm inlet through to the discharge port. This configuration facilitates consistent performance, particularly in scenarios requiring steady, non-pulsing liquid delivery over prolonged duty cycles.

    Housing the internals is a single-piece stainless steel casing, reinforced to handle operating pressures up to 16 bar. The TEFC motor is shielded under an IP55 protection rating, featuring Class 155 insulation to mitigate heat accumulation during intensive use. Mechanical seals incorporate silicon carbide and carbon components to reduce friction and leakage risks, ensuring the unit remains hermetically secure under constant load. Mounting is facilitated by a robust bracket, with the entire pump weight balanced at 12 kg for installation stability.

    Features:

    • Integrated 2-pole motor operating at 2900 rpm
    • Silicon carbide mechanical seal faces for wear resistance
    • EPDM elastomer sealing components throughout the hydraulic path
    • Compliant with ISO 9906 Grade 3B hydraulic standards
    • WRAS and ACS certified for potable water contact
    • Total Enclosed Fan Cooled motor geometry for thermal regulation
