    Environmental temperature control within closed-loop cooling systems requires precise, high-pressure fluid displacement. This unit addresses that requirement by employing a precision-engineered multistage configuration designed to handle moderate flow volumes against significant system resistance. By utilizing a horizontal mounting orientation, the assembly simplifies integration into tight mechanical plant spaces while maintaining structural stability under constant load conditions. The internal hydraulic pathway is engineered to minimize turbulence, ensuring that clean process fluids move through the system with consistent velocity, thereby supporting thermal regulation objectives in complex industrial and secondary water circuits.

    Operational threshold limits are defined by a Max Head 157 m and a Max Flow 73.3 L/Min, providing reliable performance for demanding circulation tasks. Energy conversion is managed by an IE3 efficiency class motor rated at 2.12 kW / 415v, which adheres to strict modern industrial energy standards. This electrical setup ensures the assembly functions within a 4.13 Amps current draw, maintaining operational effectiveness throughout continuous duty cycles without compromising stability in high-pressure hydraulic environments.

    Fluid dynamics are governed by a multistage impeller arrangement crafted entirely from AISI 304 stainless steel, which significantly improves the mechanical life of the rotating components when handling processed fluids. The closed impeller design is calibrated to generate high pressure gradients, allowing the unit to overcome substantial system friction losses. Internal wear rings made of technopolymer assist in maintaining tight clearances between stages, which prevents internal recirculation and preserves the integrity of the pressure output regardless of the specific load demands placed upon the system during operation.

    Protection and housing consist of a full AISI 304 stainless steel casing, offering excellent resistance against internal corrosion while ensuring compatibility with standard 25mm inlet and outlet plumbing connections. The motor assembly is rated IP55 for external protection against dust and low-pressure liquid jets, complemented by an insulation class 155 (F) for thermal stability. The entire pump configuration rests on a robust support frame, allowing for easy anchoring and alignment during installation in commercial infrastructure projects where space-efficient, horizontal mechanical equipment is specified.

    Features:

    • TEFC two-pole short-circuit squirrel-cage motor configuration
    • Silicon carbide and ceramic mechanical seal contact surfaces
    • EPDM elastomer components for broad chemical compatibility
    • Certified for potable water applications via WRAS and ACS standards
