    Environmental temperature control within industrial facilities requires the consistent movement of liquids through tight hydraulic circuits. This horizontal assembly provides the necessary steady-state flow characteristics for cooling systems, irrigation, and process water handling. Its internal design balances output consistency with energy consumption, facilitating operations in facilities requiring stable throughput and rapid pressure replenishment.

    Operational threshold limits are defined by a Max Head 20.9 m alongside a Max Flow 142 L/Min. The drive system utilizes a 0.54 kW / 415v motor, drawing a rated current of 1.33 Amps. This specific performance envelope ensures that critical circulation loops maintain velocity, supporting demanding applications where intermittent pressure variance could potentially compromise the efficiency of the broader liquid management infrastructure.

    Fluid dynamics are governed by a multistage impeller arrangement crafted from AISI 304 stainless steel to maintain hydraulic integrity under varying load conditions. By utilizing a series of stages, the unit achieves necessary pressure elevation without inducing excess turbulence. The suction dynamics allow for consistent liquid intake, minimizing cavitation risks during extended operational cycles in process-intensive environments.

    Constructed with an AISI 304 stainless steel casing, the pump unit provides significant resistance to oxidation in process water environments. The TEFC 2-pole motor is protected to IP 55 standards, ensuring that internal electrical components remain shielded from moisture and dust ingress. A mechanical seal consisting of silicon carbide and alumina provides the necessary interface protection for the shaft assembly, while the overall frame supports horizontal mounting configurations.

    Features:

    • Silicon carbide and alumina mechanical seal surfaces
    • TEFC 2-pole short-circuit squirrel-cage motor configuration
    • IP 55 ingress protection for the motor assembly
    • Class 155 (F) insulation rating for high thermal tolerance
    • Certified for use in drinking water applications
    • ISO 9906:2012 Grade 3B hydraulic standard compliance
