    Engineering Integration Notes

    1. Mechanical & Space Constraints 

    • Ultra-Compact Footprint: The pump's cylindrical body measures 27 ± 0.3 mm in diameter and 57.8 ± 0.5 mm in total length, making it highly suitable for densely packed PCB and portable device enclosures.  

    • Lightweight Design: Weighing approximately 36.0g, it strictly minimizes the overall payload for handheld medical or personal care equipment.   

    • Terminal Alignment: The lead wire terminals are located on the bottom profile (diameter 24.4 ± 0.3 mm), allowing for streamlined wire routing away from the pneumatic output.   

    2. Electrical Specifications

    • Motor Type: Brushless DC (BLDC) motor, eliminating carbon brush dust and ensuring zero electromagnetic interference (EMI) from sparking.   

    • Power Consumption: Operates at a highly efficient 2.4W across all voltage models. 

    • Current Draw Matrix: To assist with power supply design, the rated current limits are <800mA (3V), <400mA (6V), <260mA (9V), and <200mA (12V).   

    3. Pneumatic Connections & Performance 

    •  Air Tap Interface: Features a 4.2 ± 0.2 mm (OD 4.3mm) air nozzle. Engineers should select compatible flexible silicone or polyurethane tubing to ensure a secure, airtight seal.     

    • Rapid Pressurization: Designed for fast response, it achieves an inflation time of <10 seconds (from 0 to 300mmHg in a standard 500cc test tank).    

    • High Airtightness: System leakage is strictly controlled at <3.0mmHg/min (from 300mmHg in a 500cc tank), critical for sustained pressure in sphygmomanometers.   

    •  Flow & Pressure Limits: Delivers a steady flow rate of 0.5-3.0 LPM with a maximum pressure output exceeding 60KPa (450mmHg).    

    4. Lifecycle & Environmental Profile

    • Duty Cycle: The >50,000 cycles life test is validated under a rigorous duty cycle of 10 seconds ON and 5 seconds OFF. Engineers must align their software control logic with this or a less strenuous duty cycle to maximize motor longevity.   

    •  Acoustic Profile: Generates <60dB of noise (measured at 30cm). For extreme noise-sensitive bedside applications, utilizing rubber shock-absorbing mounting pads is recommended.

  • Q1: Why should I choose a brushless DC air pump over a standard brushed motor?

    A: The primary advantage is extreme durability and reliability. Our 370-XA utilizes a premium brushless motor, offering a rigorously tested lifespan of >50,000 cycles (ON 10s, OFF 5s). Unlike brushed motors, it has no carbon brush wear, which means zero friction dust, lower heat generation, and significantly reduced maintenance costs for high-end medical devices and sphygmomanometers.   

    Q2: Can the PYP370-XA be customized for our specific medical or home appliance project?

    A: Yes, absolutely. We provide comprehensive OEM/ODM services. While our standard 370-XA operates at DC 12V , we can customize the rated voltage (3V, 6V, 9V options available) , airflow (0.5-3.0 LPM) , and terminal wires to perfectly match your essential oil machines, massagers, or booster technology applications.   

    Q3: Is this micro air pump quiet enough for bedroom or portable use? 

    A: Definitely. We engineered the 370-XA with noise reduction in mind. It operates at <60dB (measured from 30cm away). Combined with its lightweight 36g body , it is the ideal choice for noise-sensitive environments, such as portable adult products, home beauty devices, and bedside medical equipment.   

    Q4: What is the inflation efficiency and maximum pressure of this 12V mini air pump?

    A: The 370-XA delivers robust pneumatic performance. It achieves a maximum pressure of >60KPa (450mmHg). For inflation speed, it can pressurize a 500cc tank from 0 to 300mmHg in less than 10 seconds, ensuring fast and stable operation for pneumatic massage systems and blood pressure monitors.
