[PSUBS-MAILIST] G.L. summary Pressure Hull

[hank pronk]

Hi Vance,
Yes it is linear, it is a very smooth and gradual.  Everything spins freely.  I may have a bit to much grease on my thrust bearing also.

Linear meaning a steady increase in demand in parallel to rising pressure. If you have a low rise with a sudden increase somewhere along the line then you may have a component not working as it should.

Hi Vance,

I was surprised how much the motor pulls down after 200psi.  I assume it is from the shaft pushing into the thrust bearing.  Also I am running the motor on 12v because it spins to fast on 24 with no load.
