Product Overview
The JSG13GE-KBD3 is a compact micro diaphragm gas pump designed for gas sampling, suction, pressure, and exhaust functions in portable instruments and space-limited OEM systems. Its 3 V coreless brushed motor drives the diaphragm mechanism to transfer small gas volumes from a pump weighing only 15 g.
This micro diaphragm gas pump delivers 300 mL/min atmospheric free flow and reaches up to 35 kPa positive pressure or -35 kPa vacuum. These figures represent separate performance endpoints because available flow decreases as inlet vacuum or outlet backpressure increases. The standard configuration draws 60 mA at free flow and operates from 5 to 40 degrees C.
The standard gas path uses a PA/PPS pump head with an EPDM diaphragm and EPDM valves. The JSG13G page covers gas service. Confirm gas composition, humidity, particles, condensation risk, and material compatibility before production approval.
Core Selling Points of This Micro Diaphragm Gas Pump
1. Compact 3 V Coreless Brushed Platform
The coreless brushed motor keeps the electrical platform simple for portable analyzers, handheld detectors, and compact board-powered pneumatic modules.
2. 300 mL/min Free Flow
The pump delivers 300 mL/min at atmospheric free flow. Use the load curve and the complete pneumatic path to determine the available flow through tubing, filters, valves, sensors, and chambers.
3. Vacuum and Positive-Pressure Functions
One compact pump platform supports suction, exhaust, and pressure generation. The published endpoints are -35 kPa vacuum and 35 kPa positive pressure.
4. 15 g Compact Installation
The body measures approximately 32.95 x 22.53 x 13.70 mm and weighs 15 g, leaving more room for sensors, batteries, control boards, filters, and sample chambers.
5. Project-Specific Configuration Options
Pump-head material, elastomer, motor type, voltage, port connection, and speed adjustment can be reviewed for OEM projects. Confirm the final part number and test data before ordering a non-standard build.

How Does This Micro Diaphragm Gas Pump Perform Under Load?
The 3 V performance curve combines vacuum-side and positive-pressure-side behavior. Negative relative pressure represents inlet vacuum; positive relative pressure represents outlet backpressure. Flow falls toward both load extremes, while current rises away from the free-flow region.
What Are the Dimensions and Installation Details?
The JSG13GE-KBD3 measures approximately 32.95 mm in overall length, 22.53 mm across the pump head, and 13.70 mm across the compact head dimension. The motor diameter is 12.00 mm. Use the complete drawing and tolerances when designing the enclosure and port clearance.
Which Media and Materials Is This DC Gas Pump Compatible With?
The JSG13GE-KBD3 is a gas pump. Its standard gas path uses a PA/PPS pump head, EPDM diaphragm, and EPDM valves. Gas compatibility depends on composition, concentration, humidity, temperature, particles, oil content, exposure time, and condensation risk.
| Gas-Path Item | Standard Material | Application Check |
| Pump Head | PA/PPS | Confirm exact resin and gas compatibility for the quoted build. |
| Diaphragm | EPDM | Validate against the real gas and exposure conditions. |
| Valves | EPDM | Validate against the real gas and exposure conditions. |
| Medium | Gas | Do not apply the JSG13G specifications to liquid or mixed gas-liquid transfer. |
What Applications Is This Micro Diaphragm Gas Pump Suitable For?
1. Portable Gas-Sampling Instruments
The 3 V supply, 15 g weight, and compact body suit handheld gas detectors, portable air-quality instruments, and small sampling modules. Select by the required flow through the real inlet tube and filter.
2. Analytical and Emissions-Measurement Equipment
The pump can move sample gas through compact analyzers, measurement chambers, and emissions-monitoring modules. Add filtration and external condensate control when the sample path requires them.
3. Compact Suction and Exhaust Modules
The vacuum side supports low-volume suction and evacuation, while the pressure side supports purge, exhaust, and low-pressure gas delivery inside space-limited OEM equipment.
4. Portable Test and Sensor Systems
The 300 mL/min flow class fits sensor manifolds, small chambers, and short pneumatic paths where size, weight, and a 3 V power platform are more important than high airflow.
How Do I Choose the Right Version of This JSG13G Configuration?
1. Define the working point. Specify the required flow at the actual inlet vacuum or outlet pressure, not only the free-flow value.
2. Confirm the 3 V power supply. Allow sufficient current for startup and 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, particles, 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 the quoted configuration. Match the final motor, voltage, pump-head material, elastomer, port, wiring, and speed-adjustment method to the approved part number.
Real Project Cases Using the JSG13G OEM Pump
Real Project Case 1: Portable Gas-Sampling Analyzer
A portable gas-sampling analyzer used a 3 V battery platform and required at least 0.20 L/min airflow at -15 kPa through a 300 mm silicone tube, a hydrophobic inlet filter, and a 30 mL sensor chamber. The available pump space was limited to 36 x 25 x 20 mm, and the working current had to remain below 100 mA. The project selected the JSG13GE-KBD3 with 2 x 4 mm silicone tubing and a low-resistance inlet filter. The integrated prototype delivered approximately 0.22 L/min at -15 kPa with a working current of about 82 mA. The 15 g pump fitted inside the handheld enclosure and maintained stable sampling during a 10-minute-on and 5-minute-off operating cycle.
Real Project Case 2: Compact Pressure-Decay Leak-Test Module
A portable leak-test instrument required a compact 3 V air pump to pressurize a 60 mL test chamber to 18 kPa within 5 seconds while providing at least 0.18 L/min airflow at 20 kPa positive pressure. The available installation envelope was 38 x 28 x 20 mm, and the system operated for 30 seconds followed by a 90-second pause. The project used the JSG13GE-KBD3 with 2.5 x 4 mm semi-rigid tubing, a low-pressure-loss solenoid valve, and a short direct connection to the chamber. The integrated prototype delivered approximately 0.20 L/min at 20 kPa with a working current below 95 mA and increased the chamber pressure to 18 kPa in approximately 4.4 seconds before the controller closed the valve and measured the pressure drop.
