low power consumption, corrosion resistance diaphragm dc vacuum air
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?
1. High temperature performance, good consistency
2. Oil resistance and easy installation
3. DC brush motor
4. Long life span, low heat.
5. Heavy duty work for 24 hours and Continuous operation
6. The key parts are imported
7. Can work for long hours
vacuum air brushless 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.
Unlabeled tolerance is ± 0.1mm.
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
brushless micro vacuum 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.
Special requirements for materials about vacuum air brushless pump

More details about brushless micro vacuum 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.
vacuum air brushless pump's application
pumps are used in many industrial and scientific processes
including composite plastic moulding processes, production of most
types of electric lamps, vacuum tubes, and CRTs where the device is
either left evacuated or re-filled with a specific gas or gas
mixture, semiconductor processing, notably ion implantation, dry
etch and PVD, ALD, PECVD and CVD deposition and so on in
photolithography, electron microscopy, medical processes that
require suction, uranium enrichment, medical applications such as
radiotherapy, radiosurgery and radiopharmacy, analytical
instrumentation to analyse gas, liquid, solid, surface and bio
materials, mass spectrometers to create a high vacuum between the
ion source and the detector, vacuum coating on glass, metal and
plastics for decoration, for durability and for energy saving, such
as low-emissivity glass, hard coating for engine components (as in
Formula One), ophthalmic coating, milking machines and other
equipment in dairy sheds, vacuum impregnation of porous products
such as wood or electric motor windings, air conditioning service
(removing all contaminants from the system before charging with
refrigerant), trash compactor, vacuum engineering,
sewage systems, freeze drying, and fusion research. In the field of
oil regeneration and rerefining, vacuum pumps create a low vacuum
for oil dehydration and a high vacuum for oil purification.
Especially in the field of transformer maintenance, vacuum pumps
play an essential role in transformer oil purification plants which
are used to extend the lifetime of transformers in the field.
