Why are imported diaphragm pumps so expensive, who recommends a cost effective domestic diaphragm pu

According to the power used by the actuator, the diaphragm pump can be divided into pneumatic, electric and hydraulic three types, namely, the pneumatic diaphragm pump with compressed air as the power source, the electric diaphragm pump with electricity as the power source, the electro-hydraulic diaphragm pump with the pressure of liquid medium (such as oil, etc.) as the power, in addition, according to its function and characteristics, there are solenoid valves, electronic, intelligent, fieldbus diaphragm pumps, etc. There are many types of diaphragm pumps, and the structure is also diverse, and they are constantly updated and changed. Generally speaking, valves are universal and can be matched with pneumatic actuators, electric actuators or other actuators.

The mode of action of the diaphragm pump is only available when the pneumatic actuator is selected, and its mode of action is formed by the combination of the positive and negative action of the actuator and the positive and negative action of the valve. Winger Machinery (Group) has....

Diaphragm pumps do not need to be imported at all, and there are many domestic diaphragm pumps that are cost-effective, such as Shanghai Wingfeng Pump Industry. Because I have bought and used it myself, I have more right to speak.

Foreign brands also have inexpensive diaphragm pumps, take a look at the diaphragm pump of Shenzhen Shipu Electric.

Hehe! You compare imported and domestic ones, and you will know why they are so expensive! You get what you pay for!

If you are singing and harmonizing to help domestic brands brush up their credibility and popularity.

Then you don't want to be like this, and the anonymous replies are in the same group as you!!

The quality competition between the brands of domestic products is also a good thing, and it is responsible for users!!

Here, I also hope that you will pay more attention to Changyu.

Have you asked Ingersoll Rand's air-operated diaphragm pump, I think this ** is okay.

Diaphragm pumps have imported and domestic, there is a certain gap between them, but compared to reliability, durability, wear resistance and other quality, it is still not as good as imported, and the evaluation of a pump can not be directly compared with sales, to consider the long-term, wearing parts service life and **, air consumption to comprehensively consider, if you really need it I can help you recommend.

The advantages of diaphragm pumps are mainly reflected in the food and chemical industries, as well as in the mining industry.

He has 2 advantages:

No oil, no electricity, using air source as the powerEspeciallychemical industry and mining industryIt reflects his advantages, and there will be no static electricity.

Relatively low shear force, used in the food industry, his relatively low shear force, can not destroy the food semi-liquid food medium.

In the long run, the effect and life of use and **, although some of the caliber is the same but the effect of use is different, if necessary, you can recommend it.
