How can the mouth ring of a centrifugal pump be removed quickly and easily? Is there any special tool for this?

It is divided into the impeller mouth ring and the pump body mouth ring. It is installed by hot fitting, and it is removed by heating it first; there are no special tools for this purpose
There’s a platform near the mouthpiece and the pump inlet; use an L-shaped small pry tool to lift it out – it’s similar to those prying claws but in reverse
They are all hand-made tools created by the maintenance staff for their own use
Some pumps have threaded holes on their mouth rings, which can be pushed out using bolts.
There aren’t many; most have only thread running along the seams
What does the seam thread look like? Are there any pictures? Are there any special prying tools or something similar to a pick?
There are no specialized tools; they are all devices created by maintenance workers through their own ingenuity.
I found a photo taken during maintenance a long time ago; it’s not very clear, but it’ll have to do for now.
There are no specialized tools, after all; there are many different sizes and ranges for mouth rings, so it’s necessary to create them customarily based on the specific circumstances
