When choosing a brushless DC water pump, you need to focus on the following performance indicators:

1. Head and flow:

- The head and flow of the DC brushless water pump need to match your actual application requirements.

- Check the head and flow parameters of the water pump to ensure that they can meet your working conditions.

2. Rated power:

- Choose a DC brushless water pump with appropriate power to meet the load requirements and minimize energy consumption.

- Too much power will lead to excessive energy consumption, and too little power will affect the use effect.

3. Voltage and current:

- The working voltage and current of the DC brushless water pump need to match the power adapter.

- Select the appropriate voltage and current specifications to ensure sufficient and stable power supply.

4. Speed ​​range:

- Understand the speed adjustment range of the DC brushless water pump to ensure that it can meet your flow adjustment needs.

- Too high a speed will increase noise and energy consumption, and too low a speed will affect the flow.

5. Service life:

- Check the service life parameters of the water pump and choose a product with reliable quality.

- Short life will increase maintenance costs and affect the user experience.

6. Protection level:

- Choose the appropriate waterproof and dustproof level according to the use environment.

- Insufficient protection level will increase the risk of failure.

Considering the above indicators and combining them with the actual application scenarios, you can choose the most suitable DC brushless water pump. If you have any questions, please continue to consult me.
