SC3401PM vs SC3402PM - How to Choose
The SC3401PM and SC3402PM share identical electrical specifications and physical dimensions. The only difference is the port configuration:
| SC3401PM | SC3402PM | |
|---|---|---|
| Outlet ports | 1 (single outlet) | 2 (dual outlet) |
| Best for | Single-tube circuits, direct-drive applications | Dual-branch circuits, simultaneous two-zone delivery |
| Typical use | Gas detector sample draw, single-cuff inflation, single-chamber aroma delivery | Dual air bag inflation, charge+vent circuit, two-stage sample delivery |
| Circuit complexity | Lower - no manifold or splitter needed | Better for parallel delivery without external splitters |
Choose SC3401PM when: your device has one output path and you want the simplest, most compact integration.
Choose SC3402PM when: your design needs to split airflow to two zones simultaneously, or you need a combined inflation/exhaust port layout.
Both models are available for OEM sampling. Specify your preferred port configuration when requesting a quote.
Why "Low Pressure" Is a Design Feature, Not a Limitation
In micro pump selection, pressure rating and flow rate are not always "more is better." Many precision applications require a stable, controlled low-pressure output rather than maximum pressure:
| Application | Why low pressure matters |
|---|---|
| Gas detectors / air samplers | Sensors require a fixed, stable sample flow - excessive pressure causes measurement errors |
| Aroma diffusers / fragrance delivery | Gentle, constant airflow disperses fragrance evenly; high pressure causes uneven bursts |
| Coffee machine steam path (auxillary) | Controlled low-pressure air purge prevents liquid backflow in branch circuits |
| Wearable pressure therapy | Gradual, controllable pressure build-up is required; rapid high-pressure inflation is uncomfortable |
| Lab gas supply | Precise flow rate control is more important than peak pressure |
The SC3401PM's 1.0 L/min flow with a stable pressure ceiling makes it the right choice wherever precision matters more than power.
Application Scenarios
| Device / System | How SC3401PM Is Used |
|---|---|
| Gas detectors & air quality monitors | Drawing air samples through sensors at controlled, stable flow |
| Aroma diffusers & fragrance delivery | Gentle pressurised airflow for consistent scent dispersal |
| Coffee machines | Auxiliary air path for backflow prevention or steam purge |
| Portable medical monitors | Low-pressure pneumatic circuits in wearable or handheld diagnostics |
| Wearable compression therapy | Gradual single-zone air bag inflation at comfortable pressure rates |
| 3D printer cooling | Low-flow directed air cooling of print head or build area |
| Laboratory instruments | Steady low-pressure gas supply for analysis chambers |
