Which company manufactures this impeller?
Thread Content
Who offers stainless steel impellers for centrifugal pumps? You can contact me; these are samples sent to me by a customer. I’ve searched the Chengdu Machinery and Electronics Market thoroughly over the past few days but couldn’t find any manufacturer capable of producing them, so I had to turn to the experts here. Thank you! This pump is used to pump salt slurry; the temperature is around 100°C, and there is some corrosion. Currently, it’s mainly the impeller of this pump that’s broken. This impeller is designed in a somewhat unusual way – it’s open on the front side but closed on the back side, and it’s cast as a single piece ； The front, back of the impeller, and the entire pump are as shown in the figure:
It’s high-end, elegant, and sophisticated; I’ve never seen such an impeller before – it’s somewhat semi-open at the front
Perform surveying and mapping, and take a spectrum of the material to determine its composition. Find a manufacturer to make a mold and cast it. If the quantity required is small, most manufacturers are unwilling to take on the order. It’s not easy to find a manufacturer that has the mold directly. You can ask the customer’s original manufacturer; it’s likely that the product can no longer be purchased from them. Check if there are any other manufacturers in the area where the original manufacturer is located.
It is recommended to replace the pump; that’s all·····
Replacing it with a semi-open impeller does not necessarily have to be an exact copy of the original impeller.
If a larger quantity is needed, molding can be done; for just one or two units, it is recommended to purchase the original ones, as they are more expensive
Communicating with the original manufacturer is one of the most efficient ways to resolve the issue; if they can’t suggest any other manufacturers, then it might be better to consider switching to a different pump
Personally, I think the protrusion below is there to facilitate mixing of the medium; as for the actual impeller that seals that area, a regular one will suffice, and we can think of other methods for mixing
The original manufacturer can no longer be found; the labels are completely corroded and impossible to read.
I think the same way; if nothing else works, the only option is to replace the pump.
