Micro Dc Water Pump

This 370 micro dc water pump is a compact yet powerful device, weighing approximately 60.0g. It offers multiple rated voltage options including DC 3.7-24V。 Impressively, it maintains a consistent power of 3.6W across these voltages, while the rated current adjusts accordingly to ensure efficient operation.

With an air tap O.D. of Ø6.5mm, it can handle a maximum water pressure of ≥30 psi , water flow of 0.8 - 1.2 LPM can be made as client’s requirement. Despite its robust performance, it operates quietly, with a noise level of ≤55db measured 30cm away.

This 370 High pressure micro diaphragm water pump excels in durability, with a life test result of ≥500 hours of continuous operation. If you chose with brushless motor lifespan will be more than 1500h. It also features an excellent pump head and suction head, both ≥5m, allowing it to efficiently move water over significant vertical distances.

Its applications are wide - ranging. Ideal for use in household appliances like water dispensers and air - conditioning drainage systems, it also serves well in medical equipment, beauty devices, and various industrial setups. Whether you need a reliable fluid transfer solution for daily use or professional projects, this 370 Micro Diaphragm water pump is a top - notch choice.

The flow rate and pressure of the 370 micro - water pump can often be adjusted, and here are the common methods:

1. Voltage adjustment

Principle: Most 370 micro -water pumps are DC - powered. By changing the input voltage within a certain range, the rotational speed of the pump motor can be altered. According to the basic relationship between the pump's performance and motor speed, when the voltage increases, the motor speed rises, usually leading to an increase in both the flow rate and pressure of the pump; conversely, when the voltage decreases, they will drop.

Limitations: However, this method has its limitations. Excessive voltage increase may overheat the motor, reducing its lifespan or even burning it out. On the other hand, if the voltage is too low, the pump may not operate stably or may fail to start.

2. Using a flow control valve

Principle: Installing a flow control valve in the pipeline connected to the micro - water pump is an effective way. By adjusting the opening degree of the valve, the resistance of the water flow path can be changed. A smaller valve opening increases the flow resistance, which reduces the flow rate. At the same time, due to the increased resistance, the pressure at the pump outlet may increase to some extent, depending on the pump's characteristics.

Benefits: This method provides relatively precise control over the flow rate and can also protect the pump to some degree by preventing excessive flow that might cause damage.

3. Changing the impeller

Principle: The impeller is a key component that affects the high pressure micro water pump performance. By replacing the original impeller with one that has different blade shapes, numbers, or sizes, the flow rate and pressure can be adjusted. For example, an impeller with a larger diameter or more blades may increase the pressure - generating capacity and flow rate under the same rotational speed.

Drawbacks: But this method requires disassembling the pump, which is relatively complicated and may void the warranty if not done properly. It also needs to ensure that the new impeller is compatible with the pump's body and motor.

In general, whether the flow rate and pressure can be adjusted and the specific adjustment methods depend on the design and structure of the 370 micro - water pump model in question.
