    environmental testing requirements about brushless air vacuum pump

    NumberItemTest conditions and requirementsRemarks
    1Steady-state heat and wet60%rhHigh humidity can affect the electrical performance of the motor
    2Temperature ShockThe 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
    3High temperature testPump 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.
    4Low temperature testFor 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

    The medium temperature of brushless air vacuum pump

    According to the temperature of the medium which pass through the pump, choose the ordinary type or the high temperature type.

    brushless air vacuum pump's dimension

    Unlabeled tolerance is ± 0.1mm.

    Pump Size:102.4*70*40mm

    Pump Weight:300g;

    Outlet:OD 5mm, silicone hose suggestion:ID 3.5mm

    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.

    More details about brushless air vacuum pump

    brushless air vacuum pump's photo

    Working principle: the rotary motion of the motor turn into the swing of connecting rod which makes the diaphragm up and down motion. In the process of the downward movement of the diaphragm, pump cavity will suck medium through the inlet valve; Upward movement of the diaphragm, pump cavity press out media through the outlet valve. Mechanical transmission parts and pump cavity is isolated by diaphragm. Diaphragm pump does not need oil for auxiliary lubricating, in the process of transmission, extraction and compression of medium.
