Features of Solar Water Pump:

1. Energy Efficiency: Solar water pumps utilize renewable solar energy to power the pump, reducing electricity costs and environmental impact.

2. Off-Grid Operation: Solar water pumps operate independently of the grid, making them ideal for remote locations or areas with unreliable power supply.

3. Low Maintenance: Solar water pumps have fewer moving parts compared to traditional pumps, resulting in lower maintenance requirements and longer lifespan.

4. Versatility: Solar water pumps can be used for various applications such as irrigation, livestock watering, and water supply in rural areas.

5. Environmentally Friendly: Solar water pumps produce zero emissions during operation, contributing to a cleaner and greener environment.

6. Cost-Effective: While the initial investment may be higher, solar water pumps offer long-term cost savings through reduced electricity bills and maintenance costs.

7. Easy Installation: Solar water pumps are easy to install and can be quickly set up without the need for extensive wiring or infrastructure.

8. Customizable Options: Solar water pumps come in a range of sizes and capacities to suit different water pumping needs, providing flexibility for various applications.

9. Reliable Performance: Solar water pumps are designed to provide reliable and consistent performance, ensuring a continuous water supply even in challenging conditions.

10. Sustainable Solution: Solar water pumps offer a sustainable water pumping solution that harnesses the power of the sun to meet water needs efficiently and responsibly.

Conditions of Use for SP pump:

1, the water temperature is not higher than 35℃;

2, the PH of the water source is between 6.5 and 8.0;

3, the solid content (weight ratio) in the water source ≤0.01%, the maximum particle diameter ≤0.2mm;

4. Maximum diving depth ≤150m.

Water flow jacket

Dongda Pumps offers a full range of stainless steel water sleeves for pumps and motors for vertical or horizontal applications.

Where the motor is not cooled enough, the use of water jacket is recommended, and the effect of its use is to extend the service life of the motor.

Water flow bushing is required in the following cases:Pump working conditions are poor, such as current imbalance, dry operation, overload, high ambient temperature, poor cooling environment, etc.

If a corrosive liquid is pumped, the corrosiveness doubles for every 10 ° C increase in temperature.If there are deposits or deposits near or on the motor.


The table indicates the longest cable length in meters for different cable specifications:

from motor starter to pump, direct starting mode.

If the star/triangle starting mode is used, the current will be lower (1×0.58),

which means that the cable length can be longer than the data in the table (Lx1.73).

For example, the operating current is less than 10% of the full load current,

the length of the cable must be 10% longer than the value in the table.

The length of the cable in the table is measured when the maximum voltage drop is 1% and 3% of the rated voltage and the water temperature is up to 30 ° C.

In order to reduce the loss during operation, the cross-sectional area of the cable can be increased compared to the value indicated in the table.

Of course, this is only suitable when the size of the well hole is appropriate and the pump has a long operating time,

especially when the operating voltage is lower than the rated voltage.

Power distribution mode

The AC220V/380V conventional power supply is converted into 12V/24V/36V low voltage power supply for low pressure fountain pump.

Distribution mode 1: Using a low-power switching power supply, a switching power supply can be realized to supply power to a low-voltage fountain pump.

2: Using high-power switching power supply, a switching power supply can be realized for multiple low-voltage fountain pumps.

The actual project can use any mode or a variety of mixed modes of power distribution, according to the user needs, site conditions and project budget.
