When your equipment requires stable airflow, precise pressure control, and limited installation space, choosing the right pump becomes a challenge. A poorly matched pump may create excessive noise, unstable output, or frequent maintenance issues. A small diaphragm pump provides a compact solution by delivering reliable air movement, vacuum performance, and pressure control for demanding applications.
Designed by JSG DC PUMP, the JSG-04A series combines compact size, efficient operation, and flexible voltage options. With DC 12V/24V input, up to 20L/min flow rate, and maximum pressure of 3.5 bar, this pump meets the needs of medical equipment, laboratory instruments, automation systems, and portable devices.

ToggleWhy Choose a Small Diaphragm Pump for Your Equipment?
A small diaphragm pump works by using a flexible diaphragm to move air or fluids without direct contact between the motor and the pumped medium. This structure helps achieve clean operation, stable performance, and long service life.
For engineers and equipment manufacturers, the JSG-04 series offers practical advantages:
- Compact structure: The pump measures only 101 × 72 × 40 mm and weighs approximately 305g, making it suitable for space-limited systems.
- Stable output: Flow rates range from 7–22 L/min with pressure up to 3.5 bar.
- Low-noise operation: Noise levels remain between 50–65 dB for noise-sensitive environments.
- Oil-free design: No lubrication is required, supporting clean applications.
- Flexible voltage options: Available in 6V, 12V, and 24V DC versions.
