### Real-World Performance Breakdown

Submersible pumps lose water volume the higher they have to push it. Here is what you can expect from this pump at varying depths:

* **At 29 meters depth:** Yields its maximum capacity of **3,000 Liters per Hour** (Great for quick tank filling).
* **At 38 meters depth:** Drops to roughly **2,000 Liters per Hour**.
* **At 44 meters depth:** Yields about **1,000 Liters per Hour** (Pushing close to its physical limit).

### Core Product Features

* **Built-in Safety Protections:** The motor is hermetically sealed and features an internal thermal overload protector. If the pump gets too hot or runs dry, it automatically cuts power to prevent the copper coils from melting.
* **Italian Copper Tech:** Built using high-grade copper windings paired with a stainless steel outer shell, giving it excellent rust resistance when permanently submersed in water.
* **Integrated Check Valve:** A built-in one-way check valve prevents pumped water from running backward into the well when the motor turns off, protecting the impellers from back-pressure wear.
* **External Control Box:** Most retail packages include a dedicated external control box that houses the starter capacitor and an easy-access reset switch.

### Vital Installation Tips

1. **Well Compatibility:** Its slim profile allows it to fit easily into narrow drilled boreholes, steel pipe casings, or open concrete ring wells.
2. **Inverter Sizing (If using Solar/Batteries):** If you plan to run this pump off a battery bank or solar inverter system, a tiny 1,000W inverter will fail. Because inductive electric motors require a heavy “in-rush” surge of current to start spinning, you will need a **Pure Sine Wave Inverter rated for at least 2,000W to 3,000W Peak** to safely handle the startup spike.
