JSG-02 Series Miniature Diaphragm Pump
The JSG-02 micro pumps are compact, high-efficiency air and fluid transfer solutions, designed for precise performance in limited spaces. Commonly used in medical, environmental, and analytical devices, they offer low noise, stable output, and long service life. With easy integration into small systems, JSG-02 micro pumps provide reliable and energy-efficient operation for a wide range of professional applications.
Customization Range: Flow 1–4L/min, Pressure 0.5–1.5bar, Vacuum -30 to -65kPa, Power 2–3W
🔧 Construction Principle
The JSG-02 miniature diaphragm pump is powered by either a brushed or brushless DC motor. It drives a flexible diaphragm through an eccentric mechanism to create clean, oil-free air pressure or vacuum. Brushless models support optional PWM control for precision flow adjustment.
