high efficiency 120kpa pressure electric diaphragm micro brushless
DC 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.

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 2 L/min and 7L/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.
micro brushless DC pump's dimension:
Unlabeled tolerance is ± 0.1mm.
Pump Size:32.8*50*70mm
Pump Weight:160g;
Outlet:OD 2.8mm, silicone hose suggestion:ID 2mm
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.
micro brushless DC pump's photo:
Brushless DC Pump uses the principle of permanent magnet brushless
DC motor which are built-in circuit board, the housing structure
designed to form the chamber for operating fluid flow,
characterized by security, because there is no brush friction, so
there is no spark; high efficiency, low power consumption
(energy-efficient, effective power of 70%) than brush motors and
long life , low noise.
Environmental testing requirements about micro brushless DC 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
