Doyin Hybrid Submersible Pump 4SD10

Description

The Doyin Hybrid Submersible Pump 4SD10 is a high-capacity water extraction system designed to bridge the gap between solar efficiency and 24/7 reliability. The “4SD10” designation indicates it is a 4-inch diameter pump with a high rated flow of 10 m3/h (10,000 liters per hour), making it one of the most powerful units in the 4-inch category.

1. High-Performance Output

The 4SD10 series is engineered for applications requiring high volume rather than extreme depth. It is often used in large-scale farming or commercial water supply.

• Rated Flow Rate: 10 m3/h (166 liters per minute).

• Maximum Head: Typically ranges from 60 to 140 meters, depending on the motor wattage (1.5kW to 3.0kW).

• Hybrid Power Input: Can take DC power from solar panels (60V–400V) and AC power from the grid or a generator (90V–240V).

2. Professional Design Features

This pump is built to handle the mechanical stress of moving large volumes of water continuously.

• Multistage Centrifugal Design: Uses a series of high-efficiency impellers to maintain pressure at high flow rates.

• Brushless DC (BLDC) Motor: Provides up to 25% higher efficiency than standard AC motors, meaning it requires fewer solar panels to achieve full output.

• AISI 304 Stainless Steel: The exterior shell, intake, and discharge are all corrosion-resistant, ensuring the pump doesn’t rust even when submerged for years.

• Smart MPPT Controller: Features an automatic switch-over that prioritizes solar power and only draws from the AC source when sunlight is insufficient.

3. Comparison with Other 4SD Series

The “10” in 4SD10 refers to the flow capacity. Here is how it compares to the models we discussed earlier:

4. Application Checklist

Because the 4SD10 moves a lot of water, your plumbing and well must be prepared:

1. Well Yield: Ensure your borehole can actually provide 10,000 liters per hour. If the well yield is low, the pump will frequently trigger its dry-run protection.

2. Pipe Size: Use a larger rising main (at least 2-inch diameter) to prevent friction loss. Using a small pipe will significantly reduce the 10 m3/h flow rate.

3. Solar Array: For the 10 m3/h model, you typically need a larger solar array (2000W to 4000W) to maintain high-speed operation.
