- Pressure, Vacuum
- Voltage
- 6V, 12V, 24V
Compact DC diaphragm pump for OEM air delivery, vacuum suction and clean-gas transfer. The JSG04A/V series offers separate pressure and vacuum versions with 6V, 12V or 24V options for medical instruments, beauty devices and compact pneumatic equipment.
- Series maximum flow: 11–20 L/min, depending on configuration.
- Pressure version: JSG04A, 2.5–3.5 bar maximum pressure.
- Vacuum version: JSG04V, −75 to −80 kPa maximum vacuum.
- Compact body: approx. 101.3 × 72 × 40 mm; approx. 305 g.
- Material options: EPDM / FKM, subject to gas compatibility and build confirmation.
Pressure & Vacuum Options
JSG04A – Pressure Type
For positive airflow, pneumatic support, small inflation modules and pressure-control circuits.
JSG04V – Vacuum Type
For suction, air extraction, gas sampling and negative-pressure modules.
Choose the required function and rated voltage. Published ranges cover different configurations. Maximum flow, maximum pressure and maximum vacuum are separate operating points; confirm available flow at your actual working pressure or vacuum.

Dimensions and Installation

Check the side mounting points, port direction, terminal access and tubing bends against the complete drawing. Allow vibration isolation and airflow around the motor.
Typical Applications
Beauty and personal-care devices, medical and laboratory instruments, gas-sampling modules, vacuum fixtures and compact industrial automation.
Important Note
For air and confirmed compatible gases. Not for liquid transfer. Review diaphragm, valve and seal compatibility if the gas path contains moisture, mist, oil vapor or chemical residue.
Tubing, filters, valves, leakage and supply voltage affect installed performance. Validate flow, startup, current, noise, temperature rise and duty cycle in the complete device before approving production.
Package Includes
1 × Selected JSG04A or JSG04V Pump
Select pressure or vacuum and 6V, 12V or 24V. Silicone hose, air filters, mounting clip, controller and power supply are not included unless agreed separately.
