DC air pump for blood pressure 6VDC ball bearings Diaphragm pump

Pump type: diaphragm pump 

Application: This model is mainly applied in blood pressure or any other atomizer use. 

Specification: 

1. Electrical characteristics:

1.1 Rated voltage: 6.0VDC
1.2 Operating voltage range: 4.0~7.2VDC
1.3 Rated current: <380mA
      The highest current is less than 380mA while pressurizing with DC6.0V from 0 to 300mmHg
1.4 Inflation time: <10s
      It takes Less than 10 seconds to pressurize with DC6.0V from 0 to 300 mmHg in a 500cc tank.
1.5 Leakage: ＜2.0mmHg
      Pressurizing from 0till 300±30mmHg in a 500CC tank, then holding for 30 seconds. After that, measuring the dropped pressure value, which   shall be less than 2.0mmHg/min.
1.6 Noise: <58DB
      Putting a 5 cm sponge under the pump, and placing it about 30 cm away from the noise meter, The evaluated noise level shall be less then 58dB while pressurizing with DC 6.0V from 0 to 200 mmHg.
1.7 Max pressure: >400mmHg
      The maximum pressure value shall be more than 400 mmHg while pressurizing with DC 6.0 V in a 500CC tank from 0 till dead-head pressure value.
1.8 Restart voltage: 3.0VDC
      Operating voltage range gas filled pressure until 200mmHg pause, And then add DC 3.0V voltage pump should restart.
