Product Overview
The JSG08A/V-D series is a dual-cylinder piston pump designed for high-volume air transfer.
The series includes separate pressure and vacuum versions.
JSG08A-D generates positive pressure for pneumatic systems.
JSG08V-D generates vacuum for air-extraction systems.
Both versions use brushed DC motors and support 12V or 24V DC power. The dual-cylinder structure suits systems that need faster air displacement than smaller diaphragm pumps.
Core Selling Points of the Dual-Cylinder Piston Pump Series
1. High Airflow from a Dual-Cylinder Structure
The dual-cylinder design delivers up to 80 L/min free flow for JSG08A-D and up to 70 L/min for JSG08V-D.
2. Separate Pressure and Vacuum Versions
JSG08A-D provides positive pressure up to 7 bar, while JSG08V-D generates vacuum up to –85 kPa.
3. Multiple Pressure Configurations
JSG08A-D offers 2 bar, 5 bar, and 7 bar pressure options for different pneumatic requirements.
4. 12V and 24V Power Options
The series supports both 12V and 24V DC power for easier system integration.
5. Aluminum-Alloy Pump Structure
The aluminum-alloy structure provides strong mechanical support and helps dissipate heat during operation.

What Applications Is This Dual-Cylinder Piston Pump Suitable For?
1. Pneumatic and Pressure Systems
The JSG08A-D is suitable for inflation, pneumatic testing, air-pressure control, pneumatic fixtures, and other pressure systems, with 2, 5, or 7 bar versions selected according to the required working pressure and airflow.
2. Vacuum and Air-Extraction Systems
The JSG08V-D is suitable for vacuum packaging, vacuum chambers, air extraction, vacuum holding, and suction systems, with selection based on target vacuum, chamber volume, and required evacuation time.
How Do I Choose the Right DC Piston Air Pump or Vacuum Pump?
1. Define the Working Pressure or Vacuum
Define the required pressure or vacuum, airflow, system volume, and filling or evacuation time before selecting the dual-cylinder piston pump.
2. Calculate System Resistance
Check tubing size, length, filters, valves, connectors, and possible air leakage because these factors can reduce actual pump performance.
3. Check the Power Supply
Choose 12V or 24V according to the system and make sure the power supply can support stable voltage and motor starting current.
4. Confirm the Duty Cycle
Confirm ON/OFF time, operating temperature, starting frequency, and working pressure or vacuum because this brushed DC pump is designed for intermittent operation.
Real Project Cases Using This Mini Compressor Vacuum Pump
Case 1: Vacuum Packaging Machine
A vacuum packaging equipment manufacturer needed to shorten the evacuation time of a 6 L chamber because the original pump became noticeably slower as the vacuum increased. After testing the JSG08V-D 24V version with 8 mm tubing, an inlet filter, and a vacuum sensor, the customer adjusted the tubing layout and reduced unnecessary flow resistance. The system could then build vacuum more quickly toward its target of about –70 kPa, while the sensor-controlled stop point kept the packaging cycle more consistent.
Case 2: Electric Airless Sprayer
An electric airless sprayer manufacturer needed a higher-flow air source because the previous pump caused slow pressure buildup and unstable output during repeated spraying cycles. The customer tested the JSG08A-D 24V pressure version and matched it with 8 mm tubing, a pressure sensor, and a pressure-relief valve. After checking the pump under the actual outlet resistance, the system achieved faster pressure recovery between spray cycles and more stable air support than the previous lower-flow configuration.
