    Irrigation systems and high-demand domestic pressure boosting are the primary service areas for this automatic kit. It is engineered to provide the high-flow performance required for large residential gardens and multi-story households. The unit ensures a consistent potable water supply for clean water applications in domestic environments.

    Hydraulic performance reaches a maximum total head of 56 m and a maximum flow rate of 120 L/Min at 50Hz. This 0.95 kW model operates on a 240v single-phase supply with a rated current of 6.2 Amps. These parameters establish the high-output hydraulic characteristics required for large-scale domestic water management.

    The pump features a horizontal multistage centrifugal assembly with self-priming capabilities up to 8m. This multistage design allows for efficient pressure build-up through successive impellers, resulting in quiet operation and high hydraulic efficiency. The system is certified to AS/NZS 4020 for use with drinking water installations.

    Construction consists of an AISI 304 stainless steel pump body and motor shaft, providing structural rigidity and resistance to rust. The hydraulic components are manufactured from fiberglass-reinforced PPO with a carbon/ceramic mechanical seal. This model is supplied as a complete kit featuring an AISI 304 pressure switch and a 20L stainless steel pressure tank.

    FEATURES

    • High-efficiency horizontal multistage centrifugal pump design for superior flow and pressure performance.
    • AISI 304 stainless steel pump casing and shaft ensure long-term durability in potable water applications.
    • Fiberglass reinforced PPO impellers and diffusers provide high mechanical strength during continuous-duty service.
    • Integrated D.R.O.P System protects the motor and hydraulics from operational faults to ensure service life.
    • TEFC induction motor rated at IP55 with Class F insulation for high-level thermal protection and safety.
    • High-grade carbon graphite and ceramic mechanical seal assembly ensures a reliable internal watertight environment.
    • Internal wear ring manufactured from PTFE ensures the maintenance of strict hydraulic tolerances over time.
    • Includes a factory-fitted AISI 304 pressure switch and a 20L stainless steel accumulation tank for automatic control.
