electric dc mini/miniature vacuum air diaphragm pump 260Kpa pressure and -75kpa vacuum
miniature vacuum air pump’s classification
Miniature gas pump is a kind of gas conveying device which is small
in volume and take gas as working medium. It is mainly used for gas
sampling, gas circulation, vacuum adsorption, vacuum pressure
maintaining, pumping, pressurizing and so on. The micro air pump
can be divided into micro negative pressure pump, micro vacuum
pump, micro gas circulation pump, micro gas sampling pump, micro
air pump and air pump according to the working principle. If
according to working theory, there are diaphragm type,
electromagnetic type, impeller type, piston type, etc. Generally,
in medical and health, scientific research, laboratory,
environmental protection, instrumentation, chemical industry and
other industries, it mainly use micro vacuum pump.
Micro pumps for pumping are divided into two categories: gas
sampling pumps and micro vacuum pumps. Although they are usually
referred to simply as miniature vacuum pumps without distinction,
they are different from each other in a technical point of view and
should be chosen with special attention.

miniature vacuum air pump's dimension
Unlabeled tolerance is ± 0.1mm.
Pump Size:102.4*70*40mm
Pump Weight:300g;
Outlet:OD 6.5mm, silicone hose suggestion:ID 5mm
Materials:pump body: PC/PPS, diaphragm: EPDM
Because we use imported ball bearing,the pump’s performance is
stable and high.
The membrane is made by EPDM and pump's body is made by special
PC/PPS which make pump well endurance and strong chemical
resistance.
environmental testing requirements about miniature vacuum air
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 |
Electrical Performance about miniature vacuum air pump
