Standard or Nonstandard:Standard
Model Number:Mini 031 Air Pump
The new 310 vacuum pump, negative pressure pump,
Can also be used as an air pump,
It should have been a negative pressure pump used in breast pumps,
The applicable voltage is DC3V-5V,
The rated voltage is DC3.7V,
This pump is small,
But the suction power is even stronger than the 370 negative pressure pump,
Its pumping capacity is also very good,
A very good micro vacuum pump, negative pressure pump.
This batch of pumps is brand new,
But the pump is basically in good condition,
But after all, it is a stock motor,
There are also a few parts of the motor that have slight oxidation marks,
Please take photos with friends who are looking for perfect appearance.
Motor: 310 motor
Applicable voltage: DC3V-DC5V (rated voltage is DC3.7V)
Voltage: DC3V current: 0.42A
Voltage: DC3.7V Current: 0.51 A (rated voltage)
Voltage: DC4..2V Current: 0.58 A
Voltage: DC5V current: 0.68 A
Weight: 37.5 g
Power on test machine,
Its suction power is very good,
Really not worse than the 370 negative pressure pump,
The pumping volume is also very good,
But one thing, please pay attention to buyers and friends,
Its noise is greater than the 370 pump,
After all, the torque of 310 motor is smaller than that of 370 motor.
Its power should be greater,
Only increase the speed,
When the rated voltage is DC3.7V, the speed reaches 6500 rpm (generally, the speed of 370 motor is about 4000 revolutions),
Close to 9000 rpm at DC5V,
Such a high speed drives the pump head,
The sound must be a bit noisy.
Please forgive me,
Our recommended voltage is still DC3.7V.
