    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 parameter and features


    1. High temperature performance, good consistency
    2. Oil resistance and easy installation

    Free Flow(L/M)








    Remark: Usually our pump has 4 kinds of voltage:6V, 9V,12V and 24V.
    When you choose pump, you can tell me the pump's voltage you need.
    We can do it for you.
    miniature vacuum air pump's dimension
    Brush Electric DC Miniature Diaphragm Air Pump 260Kpa Pressure  -75kpa Vacuum 0
    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
