Description
MODEL: LEO 4LPS14/4
LEO 4LPS14/4 is a 4-inch AC/DC hybrid solar submersible borehole pump. It is “Hybrid” unit, meaning they are built to run on both DC power (directly from solar panels) and AC power (from the main grid or a generator).
Descriptions & Constructions
- The 4LPS series pumps are “Hybrid” units, meaning they are built to run on both DC power (directly from solar panels) and AC power (from the main grid or a generator). They feature a robust AISI 304 Stainless Steel construction for both the pump and the motor, ensuring durability and corrosion resistance.
- They utilize a Permanent Magnet Brushless DC (BLDC) motor, which is significantly more efficient than traditional asynchronous motors. This efficiency reduces the number of solar panels required to achieve the desired water output.
Key Features
-
Hybrid Power Supply (AC/DC):
-
The pump can accept DC power from solar panels and AC power from the grid or a generator.
-
This allows for 24-hour operation (Solar by day, Grid/Generator by night).
-
-
Intelligent Built-in Controller:
-
MPPT (Maximum Power Point Tracking): Automatically adjusts motor speed to match sunlight intensity, maximizing water flow throughout the day.
-
Plug-and-Play: No external control box is usually required; the controller is integrated into the motor.
-
-
High-Efficiency Motor:
-
Water-cooled, Brushless DC Motor: Eliminates brush wear and increases electrical efficiency.
-
Soft Start/Stop: Protects the motor and pipework from “water hammer” and electrical surges.
-
-
Full Stainless Steel Design:
-
Pump body, motor casing, impeller, diffuser, and shaft are typically made of AISI 304 Stainless Steel, making them resistant to rust and wear.
-
-
Smart Protections:
-
Dry-Running Protection: Automatically cuts off power if the well runs dry to prevent damage.
-
Electrical Safety: Includes protection against over-voltage, under-voltage, over-current, and phase loss.
-
Thermal Protection: Shuts down if the motor overheats.
