Ask a Question About This Product

A high-power pump built for larger pools, spas, and heavy-duty applications. The Si 400 delivers maximum water flow with quiet operation and energy efficiency, making it the ideal choice for bigger pools, multiple water features, spa jets, and demanding filtration systems. Strong, durable, and designed to handle Australian outdoor conditions year after year.

Why Choose the INSNRG Si Pump?

  • Powerful, Efficient & Quiet
    The Si 400 provides the extra horsepower needed for large setups while still keeping energy use down and noise low. Its low-resistance design boosts water flow without overloading the motor, giving you reliable, cost-effective performance.

  • Durable in Harsh Conditions
    Outdoor-ready construction using reinforced polymer casing, stainless steel hardware, and P2 capacitors with an internal surge-protection fuse. Built to resist corrosion, heat, and electrical instability.

  • Fast Priming & Extended Life
    A unique internal priming weir helps the pump start faster, prevents overheating, and reduces wear on components—meaning longer service life and dependable operation.

  • Low Maintenance
    A large debris basket keeps cleaning to a minimum, giving you more time to enjoy your pool and less time maintaining it.

  • Versatile Applications
    The Si 400 (2.0HP) is suited to large residential pools, spas with multiple jets, solar heating, pool cleaners, and extensive water features. Perfect for when you need serious flow and durability.

  • Modern, Streamlined Design
    Designed for high performance but with a neat, compact appearance that fits seamlessly into any equipment area.
