low pressure,low flow, low noise dc diaphragm brushless air pump
DC brushless pump, simply,its function is to use the DC brushless
motor as the power to pump the air out from the container, or
directly pump air into the atmosphere. DC brushless pump, because
of DC brushless motor, it has long life and often be used in
conditions which need a long time continuous working . For example,
on-line gas extraction,gas pumping, gas circulation, and so on.
Because of its small size, light weight, also called a micro
brushless DC vacuum pump, micro brushless DC pump, brushless motor
vacuum pump, speed regulating vacuum pump, gas sampling pump, long
life vacuum pump.
Why we choose brushless pumps?
mini pump has the following advantages:
compact structure, maintenance free
oil free,low power consumption, corrosion resistance
high pressure,high flow, low noise
long life and other characteristics
dc diaphragm brushless air pump's parameter
Our company offers multiple component configurations allowing pump
to be used for either vacuum operation, pressure operation, or
alternating vacuum and pressure operations.The innovative, compact
design incorporates leading edge technologies that allow it to
operate harder, quieter and longer, reliable, highly efficient.
Its flow can deliver up to 3 L/min and 11L/M.
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.
You can choose pump according to our model.
In addition,it can be mounted in any position.

dc diaphragm brushless air pump's photo
An elastomeric diaphragm can be used as a versatile dynamic seal
that removes many of the limitations found with other sealing
methods. They do not leak, offer little friction, and can be
constructed for low pressure sensitivity. With the right material
consideration, diaphragms can seal over a wide range of pressures
and temperatures without needing lubrication or maintenance.
Environmental testing requirements about brushless micro 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 |
Electrical Performance about dc diaphragm brushless air pump
| Number | Item | requirements |
| 1 | Insulation resistance | 10MΩ / between wire and frame measurements , 500VDC / min |
| 2 | Dielectric strength | 5mA Max/between wire and frame measurements 500 VAC/min |
Special requirements for materials about dc diaphragm brushless air
pump
All materials comply with environmental standards.
Motors comply with EMC.
pump material is nonflammable or any fire should be fully
extinguish within 30
seconds under 10 seconds of ignition test.
More details about dc diaphragm brushless air pump
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.
Mainly used in household appliances, laboratory equipment,
environmental monitoring, gas monitoring, automotive tires and
other fields.
dc diaphragm brushless air pump's dimension
Unlabeled tolerance is ± 0.1mm.
Pump Size:82*38*62mm
Pump Weight:280g;
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.
