Problems in selecting manufacturers of circulating water pumps, diaphragm pumps and cooling water towers
Thread Content
Hello everyone, the company is going to expand production, and in response to the call for energy conservation and consumption reduction, it is planning to select some technologically advanced pumps. I searched online and found that some of the manufacturers I liked had very good web pages. However, after an on-site inspection, I found that the gap between the Internet and reality was too big. Haha, I had to keep looking. The boss asked me to post something online, so I asked for help everywhere. Oh! I also hope you all can give me some valuable suggestions! Mainly circulating cooling water pump: 720m3/h, head: 60m. In the past, a split pump from a water pump factory was used. Pumps have been developed for many years. Is there a new type of water pump with low noise, low energy consumption and high efficiency? If you have time, please help to pay attention to what types of water pumps your respective units have used. If there are any good ones, you can introduce them. There are also some pumps, such as pneumatic diaphragm pumps, hydraulic diaphragm pumps, fire pumps, mud pumps, etc. Do you have any manufacturers with strong technology that can provide them to me? Thank you. There is also a cooling water tower. The reducer on the current cooling water tower breaks down every half a year. Is there anyone who can provide one from a manufacturer that makes less noise and has a more reasonable distribution structure? Thank you!
If there are no special requirements for the circulating water pump, it is enough to use a centrifugal pump. If necessary, you can add a frequency converter to the fan, which will be better. The most suitable one is the best.
The pump we chose is from Wolong, Anhui, which is cheap, has good quality and is not small in scale... In addition, the magnetic pump in Dandong, Liaoning is also very competitive... a long-term supplier of a big domestic manufacturer...

The cooling tower fans from Shanghai and Baoding are good. We have been using them and the quality is still good. The overhaul period of the wind turbine is about 3 years, not half a year.
To be sure, Shanghai Kaiquan Pump Industry is more reassuring. Our circulating water pumps have almost no faults, and wearing parts are occasionally replaced. The cooling water tower is from Sichuan and is relatively useful. They are all used in my own practice.
The flow rate of the magnetic pump is not that large. In my impression, the flow rate is smaller. We also use Shanghai Kaiquan, but only part of it. Their price is high. But now the water pump technology is very mature. There is no problem with the quality. There is also Rizhao Water Pump Factory, which can also make pumps. This is our required flow rate.: 3000m3/h lift: 35m speed: 970r/min power: I don’t dare to say anything about the 310.4 KW reducer. In short, it is cheap but not good. We used one from a manufacturer in Shanghai. During the test run, the transmission shaft broke.
Haha, thank you for your suggestions. The price of Kaiquan is high, but as long as the quality is good and the energy consumption is low, in the long run, the one-time investment is still very cost-effective. We have also used Kaiquan's vertical centrifugal pumps, but they are smaller in size. There are many products displayed on their website, including single suction and double suction. Is there any difference in use?
The cooling tower is made by Wujin. What do you think?
