Compact brushless DC piston pump for OEM air supply, vacuum suction and gas-transfer equipment. The JSG08AB/VB-S series offers dedicated pressure and vacuum versions with 12V or 24V power options and PWM control for adjustable output.
- Pressure version: up to 45 L/min maximum free flow and 6 bar maximum pressure.
- Vacuum version: up to 40 L/min maximum free flow and −85 kPa maximum vacuum.
- Brushless motor: PWM control for system output adjustment.
- Compact installation: approx. 100 × 97 × 67.4 mm and 690 g.
- Gas-path options: EPDM or FKM seals subject to compatibility review.
Pressure & Vacuum Options
JSG08AB-S – Pressure Type
For pneumatic supply, inflation, air delivery and pressure-testing modules.
JSG08VB-S – Vacuum Type
For suction, vacuum handling, chamber evacuation and air extraction.
Select the required function and rated voltage. Maximum free flow and maximum pressure or vacuum are separate operating points. Confirm flow at your required working pressure or vacuum before selection.

Dimensions and Installation

This listing covers the compact 690 g single-head configuration shown in the photographs. Check the final drawing for mounting holes, port connections, wiring clearance and enclosure space. Allow room for tubing bends, vibration isolation and motor cooling.
Typical Applications
OEM pneumatic equipment, laboratory instruments, gas-transfer modules, vacuum handling systems, packaging support and pressure or vacuum testing equipment.
Important Note
Use clean air or confirmed compatible clean gases. Prevent liquid, condensate, dust and particles from entering the pump. Confirm seal compatibility for the actual gas, humidity and temperature.
Filters, tubing, valves, leakage and supply voltage affect installed performance. Validate starting current, loaded flow, temperature rise, noise and duty cycle in the complete equipment. Confirm the power and PWM connections before wiring; control-signal requirements depend on the selected configuration.
This is the brushless JSG08AB-S / JSG08VB-S version. Review the full model code and mechanical interfaces before replacing another JSG08 pump.
Package Includes
1 × Selected JSG08AB-S or JSG08VB-S Pump
Flowmeters, mounting clips, sealing tape, silencer, tubing, external control electronics and power supply are not included unless agreed separately.
