Features Micro DC Motor Drive: The micro pump is driven by a micro DC motor, which drives the internal mechanical eccentric movement, and drives the eccentric movement inside the diaphragm to reciprocate. Low Noise, Low Power Consumption: The negative pressure vacuum pump with bracket has the characteristics of low noise and low power consumption, and is especially suitable for occasions with high negative environmental requirements. Design with bracket: The negative pressure vacuum pump is designed with bracket, which is very easy to maintain and use, convenient and practical. High Efficiency: The negative pressure vacuum pump has the characteristics of small size, stability and reliability, and high efficiency, and the suction capacity can reach 5L/min. Main Applications: Micropumps are mainly used in medicine, gas analysis and sampling, instrumentation and other fields, with a wide range of applications.
