Product Overview
The BD-08A/V-D family includes two dual-cylinder brushed DC piston pumps for OEM equipment.
BD-08A-D → positive-pressure DC piston air pump
BD-08V-D → DC piston vacuum pump
The BD-08A-D provides up to 80 L/min free flow and is available with 2, 5, or 7 bar maximum-pressure configurations. The BD-08V-D provides up to 70 L/min free flow and up to –85 kPa maximum vacuum.
Core Selling Points of the DC Piston Air Pump Series
1. The BD-08A-D provides up to 80 L/min free flow with 2, 5, or 7 bar maximum-pressure configurations.
2. The BD-08V-D provides up to 70 L/min free flow and up to –85 kPa maximum vacuum.
3. The dual-cylinder piston structure supports high air displacement for rapid air transfer.
4. The aluminum-alloy structure provides mechanical strength and supports heat dissipation.
5. The 131 × 150 × 46 mm design combines high pneumatic output with a compact OEM installation size.

What Are the Dimensions and Installation Details?
The BD-08A/V-D measures approximately 131 × 150 × 46 mm and weighs 1.18 kg. Allow adequate installation clearance, and avoid narrow tubing or sharp bends that may restrict airflow.
Which Media and Materials Is This Mini Compressor Vacuum Pump Compatible With?
The BD-08A/V-D series is designed primarily for clean, dry air. Contact JSG DC PUMP before using other gases to confirm compatibility with the gas-contacting and sealing materials.
Recommended Media
| Media Type | Notes |
| Clean air | Standard application |
| Dry clean gas | Confirm compatibility |
| Filtered atmospheric air | Recommended where dust may enter |
| Humid air | Prevent condensation from entering the pump |
Not Recommended Without Additional Protection
| Media Type | Notes |
| Liquid water | Not designed for liquid pumping |
| Condensate | Use a water trap |
| Dusty gas | Use an upstream filter |
| Corrosive gas | Confirm material compatibility |
| Particle-containing gas | Filtration recommended |
Do not allow liquid to enter the pump. Where moisture, dust, or particles may be present, add suitable filtration or separation components before the pump.
What Applications Is This Mini Compressor Vacuum Pump Suitable For?
1. OEM Pressure and Pneumatic Equipment
The BD-08A-D is suitable for pressure generation, pneumatic equipment, inflation systems, and other OEM applications requiring relatively high airflow.
Choose the 2, 5, or 7 bar configuration according to the required maximum pressure and the required flow at the actual working pressure.
Do not estimate inflation time directly from the 80 L/min free-flow value. Tubing, valves, filters, system volume, leakage, and target pressure all affect actual performance.
2. Vacuum and Air-Extraction Equipment
The BD-08V-D is suitable for chamber evacuation, vacuum generation, suction, packaging equipment, and air-extraction systems.
Actual evacuation time depends on chamber volume, required vacuum, pump flow at that vacuum level, tubing size, filters, valves, leakage, and other system restrictions.
The 70 L/min free-flow rating therefore does not represent the flow available at –85 kPa.
How Do I Choose the Right DC Piston Air Pump or Vacuum Pump?
Select the pump according to the required flow at the target pressure or vacuum.
Confirm that the power supply can support both rated and starting current.
Confirm the required ON/OFF duty cycle and operating temperature.
Use the brushed version when cost and high pneumatic output are priorities and approximately 1,000 hours of reference motor life is suitable.
Evaluate a brushless piston pump when longer service life or more demanding duty cycles are required.
Real Project Cases Using This Mini Compressor Vacuum Pump
1. Vacuum Packaging Machine
A compact vacuum packaging machine used the BD-08V-D for a 6 L vacuum chamber with a target vacuum of approximately –70 kPa. The pneumatic system used 8 mm tubing, an inlet filter, a vacuum sensor, and automatic sealing control. The BD-08V-D provides up to 70 L/min free flow and –85 kPa maximum vacuum, giving the system strong initial evacuation capacity while maintaining sufficient vacuum for the final sealing stage.
2. Household Inflation Equipment
An industrial inflation machine for inflatable fixtures used the BD-08A-D 2 bar version with a target working pressure of approximately 1.5 bar. The system included 8 mm tubing, a pressure sensor, and a solenoid valve to stop inflation automatically at the preset pressure. The pump provides up to 80 L/min free flow, making it suitable for short-cycle industrial inflation where high initial airflow and compact installation are required.
