shielded pump

How are the shielded pumps produced by Shanghai Nikkiso? Which brand of shielded pump performs the best?
The Nikkiso product is very useful, but it’s expensive; it feels a bit like a waste. This pump usually doesn’t break down often, but when it does, it costs a lot of money. That’s my opinion, haha
We use Hammett and Dalian Empire products here. What’s interesting is that whenever circulation water is involved, we opt for Dalian Empire products; moreover, Hammett’s products don’t come equipped with bearing rotation detectors. Overall, I think Hammett’s products are quite good – they’ve never caused any problems. Of course, this is just my personal opinion, hehe…
I remember there was also a joint venture in Hangzhou, one from Germany
First, look at your medium, as the properties of the material determine your selection. Shielded pumps are used for all chlorosilanes. The pumps manufactured by Nikkiso are of high quality, but it is important to install protection mechanisms for high and low load conditions
As of now, there are no major issues with the pumps manufactured by Nippon Kikai Seisakusho. The only problem is that the overall pump temperature is on the high side; for pumps without a cooling water jacket, the temperature rises by 30 to 50 degrees above the ambient temperature, which is quite concerning. However, no problems have occurred yet.
It is widely recognized in the industry that Haimi is the best; of course, it also has the highest price at the same quality level. Haimi does not require the reverse circulation pipeline that other shielded pumps need, and its bearings are equipped with specialized systems for fault detection and background protection – no TRG detection device is required! It ranks first in the industry; the Empire has the highest production and sales volume, and ranks second overall. As for Nisshiki Seisakusho… . .
What was said upstairs is quite fair and objective
