    Corrosive, chemically active municipal supply loops benefit from the resilient stainless steel construction of this e-HM series pump. Suited for complex industrial cooling configurations and high-pressure process water requirements, the unit maintains hydraulic integrity under demanding operational cycles. It provides a stable flow path for clean, non-aggressive fluids across varied vertical and horizontal plant footprints.

    Operational threshold limits are defined by a Max Head 119 m and a Max Flow 40 L/Min. Powering these requirements is a robust IE3 efficiency motor rated at 1.15 kW / 415v, ensuring precise energy consumption relative to output. The hydraulics are engineered for sustained performance within these specified parameters, maintaining efficiency during extended load cycles.

    Fluid dynamics are governed by a multistage impeller arrangement, meticulously crafted from AISI 304 stainless steel to prevent cavitation and ensure smooth liquid transition. The close-coupled design optimizes the internal hydraulic volume, reducing turbulence and enhancing the pressure generation profile across all stages. Mechanical seal interfaces are designed to resist thermal stress, allowing for fluid handling within a range of -10°C to +120°C.

    Installation requires standard 25mm pipework connections to the suction and delivery ports. The unit features an IP55 motor protection rating, safeguarding internal electrical components against ingress in challenging environments. Mounted on a TEFC asynchronous frame, the pump facilitates easy integration into existing circulation systems, utilizing a high-efficiency 2-pole configuration for steady, vibration-dampened operation.

    Features:

    • Integrated 2-pole squirrel-cage rotor architecture
    • AISI 304 stainless steel hydraulic pump housing
    • IP55 environmental ingress protection rating
    • Silicon carbide mechanical sealing surfaces
    • EPDM elastomer components for chemical compatibility
    • Three-phase 415v electrical terminal configuration
