    Fluid transfer in specialized cooling loops requires the mechanical consistency provided by this horizontal multistage assembly. By utilizing a compact, single-piece fabricated casing, the unit maintains hydraulic integrity while operating within demanding industrial settings where space constraints frequently dictate equipment selection. It serves as an efficient conduit for clean liquids, ensuring stable circulation across process water networks and auxiliary thermal management circuits without deviating from required flow parameters.

    Operational threshold limits are defined by a Max Head 21.4 m alongside a Max Flow 73.3 L/Min. Power requirements are fulfilled by a 0.39 kW / 415v motor, which draws a rated current of 1.10 Amps during active duty cycles. These metrics ensure precise movement of fluids while maintaining energy efficiency consistent with IE3 standards for medium-scale transfer applications.

    Internal hydraulic dynamics are governed by an AISI 304 stainless steel impeller arrangement that minimizes turbulence and promotes laminar flow characteristics. The design prioritizes internal balance, reducing vibration during high-speed rotation to extend the life of the internal components. By focusing on surface-level fluid kinetic management, the pump sustains consistent suction behaviour even during prolonged operating periods, making it suitable for continuous-duty scenarios.

    Constructed with AISI 304 stainless steel, the external sleeve and hydraulic components resist chemical degradation from standard process water additives. The motor features a TEFC 2-pole, squirrel-cage configuration protected by an IP55 rating, while the electric pump assembly holds an IPX5 certification. Mounting is simplified through the standard 25 mm inlet and outlet threaded connections, allowing for direct integration into existing plumbing infrastructures.

    Features:

    • Integrated 2-pole short-circuit squirrel-cage motor configuration
    • Compliance with ISO 9906:2012 Grade 3B hydraulic standards
    • Rated for fluid temperatures ranging between -10°C and +120°C
    • TEFC motor enclosure with Class 155 insulation for thermal stability
    • Certified for use in systems requiring drinking water compatibility
    • Equipped with silicon carbide and alumina mechanical seal surfaces
