Micro water pumps can be classified into various types based on their working principles and application scenarios. Among them, the most common ones are the following:

1. Micro centrifugal pump

Micro centrifugal pump is a water pump that operates based on the principle of centrifugal force. It mainly consists of components such as impeller, pump casing, and motor. After the motor starts, the impeller begins to rotate, generating centrifugal force to suck water in from the injection port and then discharge it through the pump casing. Due to its simple structure and high efficiency, centrifugal pumps have been widely used in many fields.

2. Micro diaphragm pump

Micro diaphragm pump is a water pump that operates based on the principle of diaphragm. It consists of two diaphragms, inlet and outlet valves, transmission mechanisms, and other components. When the transmission mechanism is activated, the diaphragm will undergo deformation due to expansion and contraction, thereby achieving suction and discharge of liquid. Due to its compact structure and easy maintenance, diaphragm pumps have been widely used in fields such as chemical and medical industries.
