I think a labyrinth seal would be a great Idea. I thought of testing one.
I don’t know how tight the tolerance needs to be or how many rings would be needed to hold a pressure of 1000PSI.
A true labyrinth seal is more then a long packing gland.
I thought of a shaft cylindrical grinding a 3/8 shaft down to .1875 with six 1/16 rings 1/16 apart, the outer housing machined, split in two half’s with a cross key. The whole thing pressed into a pump housing. The labyrinth tolerance of .0005.
The shaft is pretty straight forward, it’s the outer housing that’s the tough part.
The problem is I don’t posses the skills or have the machinery to build it. There must be information and pervious data on this.
Needs more research.
