New original box original 370 large flow water pump air pump,
This type of pump is a precision and controllable micro self-priming diaphragm pump.
Generally used for medical devices, coffee machines,
Instruments or industries need pumps for precise control,
According to the incoming label, it can be seen that this pump was originally equipped with Chankun.
The food-grade water pumps on the water purifiers of these big brands of coffee machines from Electrolux,
skoocom brand air pump, the workmanship materials are very good,
Each pump head inlet and outlet are protected by soft glue nozzles,
Even the pump head screws are all stainless steel screws,
The internal structure of the pump head is similar to the double seal design of nidec pump,
Workmanship is very good.
This pump is far from the comparable 370 pump at rated voltage water flow of 1L,
In general, the flow of 370 pumps and hundreds of ml are relatively large,
However, if the buyer lowers the voltage, the flow will definitely decrease,
The specific needs of the buyer to judge,
The upper limit of flow depends on the pump head,
If the design flow of the pump head is small,
Although replacing a higher speed motor may increase the flow rate, it may increase the life of the pump head,
If you feel that this pump has a high voltage, you can also find a suitable low-voltage voltage replacement. In theory, as long as the speed meets the requirements, the replacement problem is not big.
The pump nominally rated 24V, the actual test can work from 5v,
I feel that a minimum of 10V will be better, the owner has tested with 6L of water:
Under the rated 24V voltage, the flow rate reaches 1000ml / min;
18V voltage, flow 800ml / min;
12V voltage, the flow rate still reaches 530ml / min,
It is still larger than the nominal flow of many 370 pumps.
In terms of suction range, this pump is at least 1 meter above the rated voltage,
The higher distance was not tested,
It's easy for Yang to get a two-meter tube.
As a gas pump, the flow pressure of this pump is also very good,
However, the owner did not conduct further tests.
Optimistic about getting started, does not support the return of bad reviews.
For actual use, please choose the appropriate voltage according to your own situation.
Personally feel that the 12V flow is not small,
The higher the voltage, the greater the flow pressure,
At that time, the motor was relatively easier to generate heat.
When used as an air pump,
When the voltage is lower than 10V, whistle is easy to appear in the air outlet,
Non-motor sound will disappear after installing the tube.
The pump weighs 62 grams.
