Andy,
I haven't measured the pressure,
Andy,
I haven't measured the pressure, but it does produce enough pressure to cut off the circulation in your arm when used in an automatic blood pressure monitor (sphygmomanometer). I took my pumps out of those machines, and I can bring my models up from the bottom of the deep end of my pool, and from every body of water that is safe enough to run my subs in.
The Goldmine-elec pumps, mentioned in your post, were made for the same use, in a blood pressure machine, and test OK for use in the Recirculating Compressed Air Ballast System, that I use in my models. I don't know how long this slightly different type of pump will last, but my original pumps have been used for over five years without problems.
The article on the RCABS (ballast system) is scheduled for this December's issue of the Report, but it can be seen now under Documents on my web site,
at Art Broder's Models oryou can do a Google search for Art Broder's Models and click Documents in the left column.
