Does anyone have any information on cartridge-type shielded pumps?

What is the difference between a cartridge-type canned motor pump and a regular canned motor pump? Does anyone have any information related to cartridge-type shielded pumps? Could it be shared or introduced here? It’s best to be seawater-proof. :handshake
Bag-type shielded pump? I haven’t heard of it. I know there probably aren’t any NIKKISO shielding pumps. Or is your name wrong? Are there any pictures? ? ?
It’s a tubular bag type; you saw it wrong!
What exactly is its structure and principle?
The structure should be as shown in the figure below, without shaft seals.
I have a technical proposal prepared by Dalian Empire earlier on; you can take it as a reference
In general, the shielded pump is placed inside a cylinder to meet the requirements of low-cavitation systems – many projects these days have such requirements. Both the Empire and Haimi have achieved results of varying sizes; the reference materials provided by this guy upstairs give a good idea of the situation!
A cartridge pump is actually a vertical multi-stage centrifugal pump placed inside a housing underground, with the motor above ground level; it cannot be considered a sealed pump!
