Is the question a joke?

If not, google bupke (or bupkis).  You will find descriptions such as the one on this page:


  bupkis (also bupkes, bupkus, bubkis, bubkes): emphatically nothing, as in He isn't worth bupkis (indeterminate, either 'beans' or 'goat droppings', possibly of Slavic, Vlach, or Greek origin; cf. Polish bobki 'animal droppings')[2] (MW, OED)


I'm guessing that what you cite is a description of a hard drive that looks something like a bupke.

What does “bupke” mean?
I'm looking at installing a pump for a domestic water supply with a pressure tank.  I'd like to be able to determine if a pump will shut off once it has reached pressure.

I've seen several pumps installed which seem to shut off automatically but I can't seem to figure out if this is a standard feature or not because it doesn't seem to appear in their specifications.  For example, this grundfos pump is commonly used and I've seen other grundfos's shut off automatically at pressure.  Is this standard for a jet water pump?

I am asking because I'd like to try a different brand but I can not tell if it has a built in shut off:

I've contacted the manufacturer, but with little response.  Is anyone familiar with jet pumps like this and what I should look for to fit this application?

Thanks.



EDIT:

After some time the manufacturer indicated that there is a port on the side for the pressure switch and sent a photo of one installed.  So now I know that's probably the standard way most jet pumps come so they can be externally configured to different PSI settings.
