How to distinguish between self-balancing and non-self-balancing shielded pumps
Thread Content
Our company is repairing a 55KW vertical canned pump. Due to a lack of knowledge about canned pumps, we were unaware that this pump had self-balancing capabilities; as a result, an error occurred in the g-value, which caused the pump to stop operating after just one hour of operation. Upon disassembly, it was found that the graphite bearing on the non-drive side had worn down by 1 cm – a very serious issue. I would like to ask the experts here how to determine whether this canned motor pump is a self-balancing pump. :handshake
There must be structural differences; otherwise, everything would be the same. I just don’t know how to tell the difference right now, bro:dizzy:
I guess this is an imperial shield pump; it has differences in its front bearing housing. If you’re not sure, feel free to contact me at 15242535301
