    Corrosive, chemically active municipal supply loops benefit from the resilient construction of this horizontal multistage electric unit. Targeted at industrial cooling systems and demanding process water circuits, the assembly manages high-pressure requirements while maintaining consistent flow dynamics across varied hydraulic environments. Its specific configuration allows for integration into compact skid layouts where space remains at a premium but technical output cannot be compromised.

    Operational threshold limits are defined by a Max Head 108 m and Max Flow 40.0 L/Min. Powered by a 1.05 kW / 415v motor, the unit operates with an IE3 energy efficiency profile to reduce power draw during extended service cycles. These metrics confirm the device is capable of handling significant system resistance while moving liquid volumes that align with precision cooling and secondary process supply demands.

    Fluid dynamics are governed by a multistage impeller arrangement crafted entirely from AISI 304 stainless steel. This series of internal components provides a consistent head generation that avoids typical flow fluctuations found in single-stage designs. The internal hydraulic pathway is optimized to minimize friction loss, ensuring that the velocity remains constant throughout the transition from the suction port to the discharge nozzle under varied back-pressure conditions.

    Housing consists of a high-grade AISI 304 stainless steel casing, coupled with a TEFC 2-pole motor protected to IP 55 standards. The electrical interface supports 415v three-phase supply, featuring Class 155 insulation to mitigate internal heat build-up. Installation is simplified through standardized 25 mm suction and delivery ports, accommodating standard plumbing layouts without requiring specialized adaptors or structural modifications.

    Features:

    • Integrated 2-pole squirrel-cage motor with IE3 efficiency classification
    • TIG-welded stainless steel hydraulic body for increased pressure containment
    • Silicon carbide and EPDM mechanical seal interface components
    • Suitable for continuous operation within industrial supply environments
    • Compliant with ISO 9906:2012 Grade 3B hydraulic standards
    • Operating temperature range capability from -10°C to +120°C
