FAQ
Q1: What are the typical applications for this pump?
Medical patient monitors, smart toilets, massagers, blood pressure monitors, and coffee machines – basically any device that needs fast, reliable air pressure in a compact form.
Q2: What voltage options are available?
Rated voltage range: DC3V to DC24V. Operating voltage: rated voltage ±1V. Make sure your power supply stays within that 1V window for consistent performance.
Q3: What flow rate and pressure can it deliver?
Free flow: ≥1.8L/min. Max pressure: ≥500mmHg. That's enough to pressurize a 500CC tank from 0 to 300mmHg in under 10 seconds.
Q4: How fast does it inflate?
In a 500CC tank, from 0 to 300mmHg at rated voltage - under 10 seconds. For devices like blood pressure monitors or smart toilet flushing mechanisms, this response speed is a key spec to consider.
Q5: How well does it hold pressure?
Leakage test in a 500CC tank: pressurize to 300±10mmHg, hold for 30 seconds – pressure drop should be less than 3mmHg/min. Same spec applies to 100CC tanks at 30±5mmHg.
This leakage rate is among the better performers in its class – and a critical metric for medical devices where air-tightness directly affects measurement accuracy and reliability.
Q6: How loud is it during operation?
<65dB, measured at 30cm distance with a 5cm sponge under the pump, at rated voltage from 0 to 300mmHg.
That's slightly higher than our peristaltic pumps (like SC2201RPW at ≤60dB) – but it's a higher-pressure air pump, so a bit more noise is expected. For most patient monitors and blood pressure devices, 65dB is well within acceptable range and won't affect clinical usability in typical environments.
Q7: How reliable is it? What's the lifespan?
Lifespan test: 10s inflation → 2s hold → 5s exhaust = 1 cycle. The pump can handle 50,000 cycles while maintaining flow, pressure, leakage and noise within spec.
Temperature tests: 5 hours at 5°C and 5 hours at 50°C – no performance issues. Storage temperature: -20°C to +60°C, humidity 30%–85%RH. Keep it within that range for long-term storage.
