Product Overview
The JSG16M-CBLD5 is a compact 5 V brushless DC air pump for medical testing and gas-detection instruments. It also fits portable analyzers, sampling modules, and space-limited OEM pneumatic devices. Its iron-core brushless motor drives a diaphragm mechanism to provide vacuum suction, positive pressure, or clean gas transfer from one compact pump platform.
The pump delivers at least 1.0 L/min atmospheric free flow, reaches up to -55 kPa vacuum, and generates up to 100 kPa positive pressure. These are separate performance endpoints: airflow decreases as inlet vacuum or outlet pressure increases. The pump also combines 0.5 W rated power, an unloaded current of no more than 120 mA, an 18 g body, and a service life of at least 8,000 hours.
The standard gas path uses a PA GF pump head, EPDM diaphragm, and EPDM valves. The rated voltage is 5.0 V DC, while the 3.0-7.0 V operating range supports compact battery-powered and board-powered equipment.
Core Selling Points of This Brushless DC Air Pump
1. Compact 5 V Brushless Motor Platform
The iron-core brushless motor provides a longer operating life than a conventional brushed motor while keeping the pump small enough for portable analyzers, handheld instruments, and tightly integrated medical modules.
2. Vacuum, Pressure, and Gas-Transfer Functions
One pump platform supports suction, positive pressure, and gas circulation. The JSG16M-CBLD5 reaches up to -55 kPa vacuum and up to 100 kPa outlet pressure for compact pneumatic circuits.
3. Stable Low-Flow Performance
The pump provides at least 1.0 L/min atmospheric free flow. The 5 V performance curve also shows useful airflow under moderate vacuum and backpressure, making the model suitable for tubing, filters, sensors, valves, and small chambers.
4. 18 g Lightweight Structure
The main body measures approximately 37.20 x 15.80 x 27.56 mm and weighs only 18 g. This reduces the load on portable devices and leaves more space for sensors, batteries, control boards, and fluidic components.
5. Low Power and Long Service Life
The pump has 0.5 W rated power and at least 8,000 hours of service life. It is suitable for intermittent sampling, pressure generation, leak testing, and repeated start-stop operation in compact OEM equipment.

How Does This Brushless DC Air Pump Perform Under Load?
For model selection, do not use free-flow performance alone. If the pump works through filters, tubing, sensors, valves, or a small chamber, the real airflow should be checked at the actual vacuum or pressure point. For example, a gas-sampling device should confirm the required flow at the expected inlet vacuum, while a pressure-test module should confirm the flow at the expected outlet pressure.

Which Media and Materials Is This Brushless DC Air Pump Compatible With?
The JSG16M-CBLD5 is designed for gas transfer. The standard gas path uses a PA GF pump head with an EPDM diaphragm and EPDM valves. It is suitable for clean, nonflammable, and noncorrosive gases within the 5-40 degrees C operating range.
Do not use the pump for liquids, flammable gases, strongly corrosive gases, or gas streams with uncontrolled condensation. Add filtration and a moisture separator when particles, oil mist, or water droplets may reach the pump.

| Pump Head | PA GF | Standard configuration |
| Diaphragm | EPDM | Standard configuration |
| Valves | EPDM | Standard configuration |
| Medium | Gas | Clean, nonflammable, noncorrosive gas |
| Customization | PA or PPS; EPDM or FKM | Available for project-specific configurations |
What Applications Is This Brushless DC Air Pump Suitable For?
1. Medical Testing and Diagnostic Equipment
The JSG16M-CBLD5 can provide low-flow suction, positive pressure, purge air, and gas transfer in portable medical analyzers, respiratory testing modules, compact diagnostic instruments, and sample-handling systems.
2. Gas Sampling and Detection Instruments
The pump can move sample gas through tubing, an inlet filter, sensors, and a small measurement chamber in gas detectors, environmental monitors, air-quality instruments, and emission-testing modules.
3. Pressure and Leak-Test Modules
The 100 kPa pressure capability supports small pressure-build, leakage-check, valve-test, and airtightness-test circuits that require a compact 5 V air source.
4. Compact OEM Pneumatic Systems
The 18 g structure and 5 V platform suit handheld devices, battery-powered modules, portable test instruments, miniature automation equipment, and other products with limited installation space.
How Do I Select the Right JSG16M Configuration?
1. Define the working point. Specify the required airflow at the actual inlet vacuum or outlet pressure, not only the free-flow value.
2. Confirm the power supply. Use a regulated 5 V DC supply and allow enough current for the highest expected pneumatic load.
3. Check the full gas path. Include tubing length and bore, filters, valves, fittings, sensors, chambers, and expected leakage.
4. Confirm gas compatibility. Provide the gas composition, concentration, humidity, temperature, particle level, oil content, and condensation risk.
5. Define the duty cycle. Confirm continuous run time, pause time, start-stop frequency, target life, temperature rise, and noise limit.
6. Confirm installation details. Check port direction, lead length, connector, mounting holes, enclosure clearance, ventilation, and vibration isolation.
Real Project Cases Using This Brushless DC Air Pump
Real Project Case 1: Portable Gas-Sampling Analyzer
A portable gas-sampling analyzer used a 5 V power platform and required at least 0.55 L/min airflow at -20 kPa through a 300 mm silicone tube, an inlet filter, and a compact sensor chamber. The available pump space was limited to 40 x 20 x 30 mm, and the target operating pattern was 10 minutes on and 5 minutes off.
The project selected the JSG16M-CBLD5 with 2 x 4 mm silicone tubing and a low-resistance inlet filter. The integrated prototype delivered approximately 0.60 L/min at -20 kPa with a working current below 160 mA. The 18 g pump body fit inside the handheld enclosure without changing the battery layout.
Real Project Case 2: Compact Medical Pressure-Test Module
A medical-component test fixture required a 5 V micro air pump to pressurize a 120 mL test chamber to 35 kPa within 6 seconds. The design target was at least 0.60 L/min at 40 kPa, with a maximum installation envelope of 45 x 25 x 35 mm.
The project used the JSG16M-CBLD5, 2.5 x 4 mm hard tubing, and a short direct connection between the pump and chamber. The prototype delivered approximately 0.65 L/min at 40 kPa, operated at about 185 mA, and reached 35 kPa in 5.8 seconds. The system then closed a solenoid valve and measured pressure decay to complete the leak test.
