SC2701XPM Low-Noise Micro Diaphragm Air Pump (DC 3V / 6V / 12V / 24V)
Current Standard Model: SC2701XPM | Old Model: SC3701PM (100% Drop-in Backward Compatible)
High-precision micro diaphragm air pump engineered for medical blood pressure monitors, automatic coffee machine purge systems, and intelligent toilet bidet bubble wash units. Delivering >1.8 L/min airflow, >60 kPa positive pressure, medical-grade <3 mmHg/min airtight holding, and 50,000 endurance cycles within a compact ø27mm footprint.
Engineered for Clinical Blood Pressure Cuffs, Commercial Coffee Purge & Smart Bidets
- Medical-Grade Airtightness (<3 mmHg/min Leakage): Internal elastomeric check valves ensure near-zero pressure loss during the 300 mmHg holding phase, preventing oscillometric pulse wave distortion in digital sphygmomanometers.
- Rapid <10-Second Inflation (500cc Cuff): Rapidly inflates adult arm cuffs from 0 to 300 mmHg in under 10 seconds, minimizing patient arm discomfort and vascular congestion.
- Deep Positive Pressure Head (>60 kPa / >450 mmHg): Easily overcomes downstream solenoid valve restrictions and fluidic back-pressure in automatic coffee machine brew chambers and bidet nozzle injection lines.
- 50,000 Heavy-Duty Pulse Cycles: Tested under rigorous 10s ON, 2s OFF, 5s EXHAUST cyclic stress, ensuring multi-year maintenance-free reliability in commercial brewers and home sanitary appliances.
- Whisper-Quiet Operation (46–52 dB Typical): Advanced internal multi-chamber dynamic balancing limits acoustic noise strictly below 60 dB, preventing mechanical vibration pickup by sensitive piezoresistive pressure sensors.
- Full Voltage Platform Versatility: Available in DC 3.0V, 6.0V, 12.0V, and 24.0V configurations with operating currents as low as <300 mA (24V) and <650 mA (6V) for dry-cell and lithium-ion portability.

Application Focus: Fluidic Dynamics in Target OEM Devices
1. Clinical Digital Arm-Type Blood Pressure Monitors (Sphygmomanometers)
Digital arm-type sphygmomanometers require smooth, linear cuff pressurization followed by controlled step-deflation to detect arterial oscillation amplitudes. SC2701XPM inflates standard 500cc cuffs in under 10 seconds. Crucially, its internal sealing limits pressure leakage to under 3 mmHg/min, eliminating pressure drops that cause oscillometric signal distortion or E-3 cuff error alarms.
2. Espresso & Capsule Coffee Machines (Air-Purge & Anti-Drip Systems)
At the end of an espresso extraction cycle, residual coffee liquor in the pod chamber can cause continuous post-brew dripping and mold buildup. SC2701XPM delivers >60 kPa positive pressure to inject clean, oil-free air into the brew chamber, purging trapped droplets into the cup and drying the nozzle line for superior hygiene.
3. Intelligent Toilet Seats & Smart Bidets (Aerated Water & Nozzle Purging)
Smart bidets utilize aerated bubble washing to produce softer, more comfortable cleansing jets while reducing water consumption. SC2701XPM injects steady >1.8 L/min micro-air streams into the pressurized water manifold to generate micro-bubbles. With a 50,000-cycle life rating, it handles years of frequent residential and hotel usage without diaphragm fatigue.
