    High-flow residential water supply and garden irrigation are the main applications for this automatic pressure boosting kit. It manages clean water transfer in settings where multiple outlets must be supplied simultaneously without pressure loss. The unit provides a technical solution for homes requiring a high-volume potable water supply from rainwater tanks.

    Performance specifications for this 0.75 kW model indicate a maximum total head of 44.5 m and a maximum flow rate of 120 L/Min. Drawing a rated current of 4.7 Amps on a 240v single-phase supply, the motor provides the hydraulic output for large domestic dwellings. These data define the capacity for high-demand residential water networks.

    Mechanical delivery is provided by a self-priming horizontal multistage centrifugal design capable of 8m suction lift. This configuration focuses on maximizing flow efficiency while maintaining the quiet operation expected in residential areas. The design is fully certified under AS/NZS 4020 for the transfer of drinking water.

    Structural construction features an AISI 304 stainless steel pump casing and motor shaft, ensuring mechanical durability and corrosion resistance. The internal rotating assembly utilizes fiberglass-reinforced PPO components and a carbon/ceramic mechanical seal. This model is supplied as a kit with an AISI 304 pressure switch and a 20L stainless steel pressure tank.
