Battery powered transfer cheap mini diaphragm 12 volt dc vacuum pump
how to choose pump?
In short, the gas sampling pump can only carry a small load (i.e., the pump suction end’s resistance can not be too big, but the price is cheap; in the strict sense, the miniature vacuum pump can carry a large load (the suction end allows large resistance, or even completely clogged up, but the price is slightly higher. The resistance of the pump can be measured by means of instrument. Comparing it with the por of maximum allowable resistance of air inlet in the pump's technical parameter, we can know whether the type selection is appropriate or not. It is usually determined by a simple method based on experience. For example, the following conditions are of high load (that is, the pumping end of the pump has greater resistance and can only be selected within the scope of the miniature vacuum pump):
1.At the pumping end of the pump to be connected to a very long pipe, or pipe bending points, severe bending will even block closed, or the pipe has a very small hole (for example, less than φ 2 mm);
2.There are throttle valves, solenoid valves, air path switches, filters and other components on the pipeline;
3.The pump outlet is connected with the closed container, or the container is not airtight but the air intake is small;
4.The pump outlet is connected with the closed container, or the container is not airtight but the air intake is small;
5.The pumping end of the pump is connected to the filter container, which is used to speed up liquid filtration.

environmental testing requirements about 12 volt dc vacuum pump
| Number | Item | Test conditions and requirements | Remarks |
| 1 | Steady-state heat and wet | 60%rh | High humidity can affect the electrical performance of the motor |
| 2 | Temperature Shock | The pump was placed at -20 ℃ environment ,after 1h immediately placed at + 70 ℃ ± 3 ℃ environment for 1h.This is for 1cycle. After 50 cycles was returned to room temperature.0.5h later,pumping power test is conducted. The pump should be able to work properly; fasteners should not loose , in working condition pump’s body should not be leakage when block pump’s outlet. | too high temperature affect pump’s parameters, life and electrical performance |
| 3 | High temperature test | Pump is at 70 ℃ ± 3 ℃ environment for 48h. Then take it out. After 0.5hours later, at room temperature power pump. Fastening points should be no loose. The pump can work normally. Its performance and parameters can not change. | |
| 4 | Low temperature test | For 72 hours,pump is at -20 ℃ environment. Then take it out. Power the pump and test it.( when testing the pump,pump’s body can not have ice ). Fastening points should be no loose. The pump can work normally. Its performance and parameters can not change. | In too low temperature,motor cannot be started |
