brushless air pump

,

miniature electric vacuum pump

closed diaphragm surface and special sealing system diaphragm electric brushless electric motor 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.

 

how to choose pump?

 

In short, the gas sampling pump can only carry a small load (i.e., the pump suction end’s resistance can not be too big, but the price is cheap; in the strict sense, the miniature vacuum pump can carry a large load (the suction end allows large resistance, or even completely clogged up, but the price is slightly higher. The resistance of the pump can be measured by means of instrument. Comparing it with the por of maximum allowable resistance of air inlet in the pump's technical parameter, we can know whether the type selection is appropriate or not. It is usually determined by a simple method based on experience. For example, the following conditions are of high load (that is, the pumping end of the pump has greater resistance and can only be selected within the scope of the miniature vacuum pump):

1. At the pumping end of the pump to be connected to a very long pipe, or pipe bending points, severe bending will even block closed, or the pipe has a very small hole (for example, less than φ 2 mm);

2. There are throttle valves, solenoid valves, air path switches, filters and other components on the pipeline;

3. The pump outlet is connected with the closed container, or the container is not airtight but the air intake is small;

4. The pump outlet is connected with the closed container, or the container is not airtight but the air intake is small;

5. The pumping end of the pump is connected to the filter container, which is used to speed up liquid filtration.

 

 

brushless electric motor 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.

Closed Surface Mini Diaphragm Vacuum Pump , DC Micro Air Pump 200kpa Pressure 0

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.

 

brushless electric motor 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

More details about brushless electric motor pump

 

Closed Surface Mini Diaphragm Vacuum Pump , DC Micro Air Pump 200kpa Pressure 3

 

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.
