What is the self-priming function of micro submersible pumps？
The self suction function of a Micro Submersible Pump refers to the ability of the Submersible Pump to automatically suck liquid into the pump when started, without the need for manual filling or external use the process of partial suction assistance. This function is usually achieved through the special design and structure of submersible pumps, such as by expanding the inlet, setting inlet filter screens, and set up suction chambers or reflux holes inside the pump body. When the submersible pump is started, the self suction function helps the pump quickly dispense liquid inhalation and discharge by the body, thus avoiding the tedious process of traditional submersible pumps requiring manual filling or waiting for the liquid to flow in on its own. this function makes micro submersible pumps more convenient and efficient, suitable for various pumping situations, especially those that require frequent start-up or liquid flow rate unstable situations.
Are all micro submersible pumps self priming?
Not all micro submersible pumps are self priming. The type and performance of micro submersible pumps vary depending on brand, model, and design. Some micro submersible pumps may have self suction function, which means they can automatically suck and discharge liquids without external assistance. However, there are also some micro submersible pumps that require manual liquid filling or the use of external suction to assist in starting the pump's operation.
How is the self suction function of a Mini Submersible Pump achieved?
The self suction function of micro submersible pumps is mainly achieved through the internal structure and design of the pump. Generally speaking, the self suction function of micro submersible pumps is achieved through the design of the following aspects:
1. Water inlet design: The water inlet of a DC Submersible Pump usually adopts a special structural design, such as expanding the water inlet, setting an inlet filter screen, etc., to increase the inlet area and prevent impurities from entering the pump, so as to facilitate the automatic suction of liquid by the pump.
2. Pump body structure: The pump body of a micro submersible pump usually adopts a special structure, such as setting up a suction chamber, reflux holes, etc., so that the pump can automatically suck liquid into the pump and achieve self suction function when starting.
3. Gas liquid separation design: Some micro submersible pumps also install a gas liquid separation chamber inside the pump body, which separates gas and liquid through centrifugal force to avoid gas entering the pump and affecting the pump's working effect, thereby ensuring that the pump can automatically suck in liquid and achieve self suction function.
It should be noted that not all pumps have the self suction function of micro submersible pumps, and it needs to be judged based on specific product models and performance.
How does the self suction function of a Small Submersible Pump improve efficiency?
The self suction function of micro submersible pumps mainly improves efficiency by reducing the gas in the inlet pipeline and increasing the inlet flow rate. When the submersible pump has a self suction function, it can automatically suck the liquid into the pump, avoiding the tedious process of manual water filling. This reduces the gas content in the inlet pipeline, as gas usually does not participate in the pump's pumping process, thereby improving the pump's pumping efficiency.
In addition, the self suction function ensures sufficient inlet flow. Flow rate is one of the important parameters for the performance of submersible pumps, and sufficient inlet flow rate can ensure stable operation and efficient pumping of the pump. The self suction function optimizes the design of the inlet pipeline and pump body structure, making it easier for the pump to suck in liquid, thereby ensuring sufficient inlet flow.

What other factors need to be considered when purchasing a mini submersible pump besides its self suction function?
When purchasing a micro 1.5 inch submersible pump, in addition to the self suction function, the following factors need to be considered:
1. Flow rate and head: Determine the required flow rate and head according to actual needs to ensure that the selected submersible pump can meet pumping requirements. Flow refers to the amount of liquid pumped by a submersible pump per unit of time, while head refers to the height to which the submersible pump can pump the liquid.
2. Power and voltage: Determine the required power and voltage according to actual needs to ensure that the selected submersible pump can operate normally and meet local power supply conditions. Power refers to the electrical power required by the submersible pump, while voltage refers to the power supply voltage required by the submersible pump.
3. Material and corrosion resistance: Select suitable materials and corrosion resistance according to the usage environment and liquid properties to ensure the long-term stable operation of the submersible pump. For example, if the liquid contains corrosive substances, it is necessary to choose materials with good corrosion resistance.
4. Noise and vibration: Choose low noise and low vibration submersible pumps according to the usage situation to avoid interference with the surrounding environment and personnel.
5. Price and Quality: When selecting submersible pumps, it is necessary to choose appropriate brands and models based on actual needs and uses, and pay attention to comparing and selecting based on market prices and quality evaluations.
