Kailo 4.0 HP Submersible Water Pump

The Kailo 4.0 HP Submersible Water Pump is a heavy-duty, high-capacity water pumping system. Stepping up to 4 Horsepower transitions the hardware into commercial, industrial, and deep-well agricultural infrastructure territory.

It is uniquely engineered with a massive multi-stage vertical lift capability, enabling it to pull water from deep underground aquifers that would easily stall smaller residential pumps. It is widely available in standard single-phase (220V AC) variants, as well as three-phase versions for commercial grids.

Key Specifications & Performance

Real-World Head vs. Flow Rate Curve

With a 4 HP motor, the hydraulic pressure inside the multi-stage impeller stack is massive. However, water volume decreases the higher the pump has to lift the water column:

• At 145 meters depth: Delivers its highest output rate of roughly 3,000 Liters per Hour ($\approx 50 \text{ L/min}$).

• At 190 meters depth: The output tapers to about 2,000 Liters per Hour ($\approx 33 \text{ L/min}$).

• At 220 meters depth: Reaching its absolute physical maximum lift capacity; the flow slows to roughly 1,000 Liters per Hour ($\approx 17 \text{ L/min}$).

Core Structural Features

• High-Lift Multi-Stage Engineering: Features a reinforced stack of internal impellers designed to handle the crushing back-pressure of water columns up to 220 meters high without cracking or warping.

• Corrosion-Resistant Armor: Built using a 304 stainless steel body paired with a solid brass top outlet section. This prevents rust or thread stripping under immense line pressure.

• Hermetically Sealed Motor Core: The 3.0 kW motor features 100% heavy copper windings designed for long, continuous runtime cycles in agricultural irrigation or commercial water distribution networks.

• Integrated Mechanical Check Valve: Built straight into the discharge head to block high-pressure backflow from smashing down into the impellers when the system powers down.

Critical Power & Generator Matching

A 4 HP induction AC motor requires a massive amount of starting current (in-rush amperage) to get the internal components spinning. Running this pump on under-sized power infrastructure will instantly destroy the starter capacitors or stall your power source.

• Mains Electricity: If running the single-phase model, it must be wired directly to a dedicated, high-amperage circuit breaker (minimum 40A to 50A breaker layout recommended) to isolate the startup surge from your main panel.

• Generator Requirements: To run this pump on a remote farm or borehole site, a standard portable generator will choke instantly. You need a minimum 13 kVA to 15 kVA gasoline or diesel generator to safely handle the inductive startup spike.

• Solar Inverter / VFD Systems: Running a 4 HP AC pump on solar requires a specialized 3.0 kW (or higher) Solar Pump VFD Controller (Variable Frequency Drive) that can translate DC solar energy directly into AC power with a built-in soft-start mechanism to completely bypass the high-amp startup spike.
