7L/M flow electric 12 volt dc vacuum diaphragm medical pump
Judging the working condition of exhaust end of miniature pump
The above problem is to discuss the suction end resistance of the
pump. According to these conditions, the range of selection has
been reduced, but the problem of exhaust end resistance must be
considered. In this way, the optional range can be determined.
In practical application, the exhaust condition of the micro vacuum
pump is different: one is that the exhaust is very smooth and goes
straight to the atmosphere; the other is the high exhaust
resistance, such as valves, small bends, and large damping sensors
on the exhaust pipe road, Non-specific silencers, exhaust below
liquid level, gas to airtight or semi-closed containers, etc. In
modern design and manufacture, the micro vacuum pump with different
exhaust conditions is treated differently. " The parameter of the
maximum resistance Por value "is to calibrate the exhaust capacity
of the pump, so we can use strict technical means to determine
whether the type selection is appropriate or not."
According to the above steps, we have been able to determine the
selection range of the micro pump. The allowance should be left for
the selection of the attention parameters, especially the flow
parameters. After the pump is connected to the gas path system, the
pressure loss will be caused by the pipeline, valve and other gas
elements, so the flow rate is smaller than the nominal flow rate of
the pump, and some problems related to the selection of the pump
are listed below, which are considered according to the application
12 volt dc vacuum pump's parameter and features
1. Small and powerful
2. Extreme chemical resistance
3. Brush and brush-less direct current motor for selection
4. Dry running, durable and maintenance free
5. Self-priming and excellent for pressure
6. Low noise, longer endurance lifetime than other normal membrane
Remark: 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.

12 volt dc vacuum pump's packing and shipping
G.W. : 19.5 KG
DIMENSION : 47 * 31 * 25 CM
We can ship pumps to you by sea, by air or by express.
By sea: cheap but long
By air: quick but a a little expensive
By express: door to door, 3-5days to your country by
DHL/UPS/FEDEX/TNT and others.
The fastest, but most expensive.
You can choose according to your needs.
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.
Founded in 1999, Yanhua faith is concentrated on the micro pump
field’s research and development for 20year, we are only company in
China whose positioning is to supply and produce high-end brushless
DC pumps and brush dc pump to all countries ,aiming “to be the dc
micro pump field leader and the most influential enterprise”. Just
like many professional foreign excellent companies, they focus on
one product fro centuries and make the product and the best one in
their respective field, this is also what Yanhua Faith pursue.
Under this pursuit,our company’s quality police has been targeted
at “by the creative spirit ,setting up the micro pump industry’s
benchmark, and building up the international high quality”. We
devote to 20% profit to R & D department, so we have more than
20 patent in research dc micro pump.
All products of our company have independent intellectual
property rights and patents.
We have all kinds of certification, such as Rohs,CE and Reach.
