Compact Size


The internal space of a tea bar machine is limited. Micro diaphragm pumps feature a compact size, making them easy to install in the narrow space inside the tea bar machine without occupying excessive space. This facilitates the compact design and rational layout of the tea bar machine.


Strong Self-Priming Capacity


Micro diaphragm pumps possess excellent self-priming functionality, enabling them to easily draw water from buckets placed at lower positions. No manual water filling is required, ensuring convenient use and a stable water supply for the tea bar machine.


Low Noise


Tea bar machines are usually placed in environments that require quietness, such as homes and offices. Micro diaphragm water pump operates with low noise (generally below 45dB when pumping water) and does not produce obvious noise interference, providing users with a quiet usage environment.


Good Sealing Performance


The sealing design of micro diaphragm pumps can prevent liquid leakage, avoiding faults like internal circuit short circuits of the tea bar machine caused by water leakage. This enhances the safety and reliability of the tea bar machine while also preventing water waste.


Dry-Running Capability


Micro diaphragm pumps can run dry continuously for a long time. This feature ensures that the water pump will not be damaged due to dry running when the tea bar machine has a low water level or temporary water shortage, improving the durability and stability of the tea bar machine.


Low Energy Consumption


Micro diaphragm pumps have low energy consumption, which meets the energy-saving requirements of tea bar machines. These miniature pumps can effectively save energy, reduce usage costs, and simultaneously minimize environmental impact.


Low Maintenance Costs


Micro diaphragm pumps have a simple structure and no complex mechanical components (such as vulnerable parts like impellers and bearings). No frequent maintenance or part replacement is needed during daily use, reducing users' usage costs and maintenance difficulty.


Stable Output Pressure


They can provide relatively stable water pressure, ensuring smooth water outflow from the tea bar machine. Whether fetching water or brewing drinks, the water flow rate will not fluctuate significantly due to pressure changes, enhancing the user experience.


Moderate Water Flow


The water flow rate of micro self-priming pumps is generally 500-2500ml/min. Usually, a tea bar machine only needs 1000-2000ml of water to brew a pot of tea, so the water flow is moderate.
