Mini water pumps, with their ability to efficiently circulate, transport, and pressurize various liquids, are widely used in multiple industries. Their compact design, consisting of a driving part and a pump body with an inlet and an outlet, allows for easy integration into different systems. The water enters from the water inlet and the other outlet. The mini water pump is generally small in size, light in weight, and has anti-interference, long life and high temperature resistance (100 ℃).It is usually powered by DC, noiseless, and can be used continuously for a long time. It is commonly used in household appliances, industry, laboratories, and other places. It has the advantages of small size, light weight, easy operation and maintenance, and is therefore widely used in various fields. There are many types of mini water pumps, such as submersible pumps, self-priming pumps, diaphragm pumps, etc. Different models can be selected according to different needs.

Mini water pump's key components, such as the electric motor (which can be DC or AC type), work together to ensure the efficient operation of the pump. The motor drives the pump body, with the help of the shaft and bearings that support and transmit power, to extract and discharge liquid through the precisely designed inlet and outlet. The pump cover, fitting tightly with the pump body, is essential for maintaining the integrity of the liquid extraction process in the compact mini water pump.

Mini water pumps' small size and light weight make them ideal for applications where space is limited, such as in household appliances like Water heater pumps or in compact industrial equipment. Their easy operation and maintenance, along with high efficiency and low energy consumption, contribute to their excellent performance in energy conservation, which is highly valued in today's environmentally conscious world.

Mini water pumps are classified into DC and AC types based on voltage. 

The various voltage options of DC mini water pumps, including 3v, 6v, 12v, 24v, 36v, and 48v, are designed to meet different power supply requirements in diverse applications, such as in low-power portable devices or solar-powered systems. 

AC mini water pumps with voltages like 220v and 240v are commonly used in household and industrial applications where standard power sources are available, providing reliable power for efficient liquid pumping operations.

According to the working principle, mini water pumps can be divided into: volume pumps, vane pumps and other types.

The positive displacement pump is divided into: diaphragm pump, piston pump, gear pump, etc;

Vane pump is divided into centrifugal pump, axial flow pump and mixed flow pump.

Mini water pumps are further categorized into submersible and non-submersible types. Submersible mini water pumps are designed to operate underwater, with features like waterproof sealing and corrosion resistance, making them suitable for applications such as aquarium filtration, well pumping, and underwater construction. Non-submersible mini water pumps, on the other hand, are used in above-water applications where they can efficiently pump liquids without the need for submersion, like in small-scale irrigation systems or industrial coolant circulation.

Applicable fields of mini water pump

1. Mini water pumps play a vital role in the automobile industry. They are specifically designed to meet the demanding requirements of cold starting automobile engines in extremely low temperatures (-40 ℃ in winter) and circulating heat dissipation of fuel engine antifreeze at high temperatures (up to 120 ℃). Moreover, they are also essential for efficient water circulating heat dissipation in electric vehicles and electric motorcycles, ensuring the optimal performance and longevity of automotive systems.

2. Solar photovoltaic energy products: solar water pump is to use solar panels to directly drive the water pump to work. The mini water pump has three major functions:

(1) Energy-saving, 35% less than ordinary DC brush water pump

(2) Soft start function, normal start within 1W power

(3) It is convenient to set the overvoltage protection function.

3. Food industry:

Miniature water pump is mainly used for small products such as dishwasher, coffee machine, water dispenser, etc. The shell of the water pump can be made of special food-grade high-temperature resistant materials, and the mini-pump can work normally for more than 100 degrees continuously. It can reach food grade.

4. Household products: aquarium, fountain, foot bath, shower, water heating mattress, computer water cooling system, etc; The DC brush water pump has the characteristics of low noise, long service life and good pressurization effect, which can fully meet the above requirements.

5. Mechanical equipment and chemical products: machine tool equipment water circulation heat dissipation, water chiller circulation heat dissipation, sewage purification and other industries.
