Manufacturer for replacing pump components

I’m consulting with senior colleagues: if we don’t use original manufacturer parts, what parameters does a different manufacturer need to provide in order to replace them? Is it necessary to have a new manufacturer measure the data? For example, can the mechanical seal model DST65 be used on its own? Or can it be matched by providing a pump model of CQB65-40-100?
Conduct on-site surveys; the manufacturer for replacing the mechanical seal should not present any problems. As for the pump’s own components such as the impeller, corresponding calculations are required.
It’s not necessary to use the original one; it can be made by measurement. Shafts and such. Even for the impeller, similar products from other manufacturers can be found, as well as for the mouth ring. Sealing is simpler – just test the shaft sealing chamber by yourself
Things like machine seals and bearings can definitely be replaced without using those supplied by the original manufacturer; however, for components related to the pump’s hydraulic system, such as the pump shaft, impeller, and volute, it is necessary to consult the original manufacturer.
For machine seals, as long as the model is correct there’s no problem; it’s best to have the supplier from the factory come to the site to take a look and make measurements. To avoid trouble. There are still differences in sizes among them
This needs to be treated differently; those who don’t buy original parts feel that the prices of original accessories are too high. What was said on the 4th floor is correct; when it comes to things like flow channels, impellers, and pump casings, it’s best to use original parts. Just in terms of price, sometimes the cost of having it processed outside can be higher than that of the original manufacturer’s version.
Generally, on-site surveying is required; relying solely on the equipment model can lead to problems
When it comes to mechanical seals, there are often discrepancies in the provided seals as well as the model numbers of the main machines. Seal models are often assigned by the manufacturers themselves; even for machines of the same model from the same manufacturer, seals can differ depending on the date of production. It is more accurate to provide the installation dimensions of the product currently in use
Thank you. Is it really necessary for the manufacturer to come to the site for surveying?
When switching to a different manufacturer’s product, it’s impossible for them to explain things clearly, right?
Yeah, mainly it’s probably because the price will be high; once there are no other options, it’s hard to know what to do
