Is it common to have a pressure shut off for Jet Water Pumps

pumpwell-pump

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.

It is not a standard feature. The pump often hooks into a manifold that connects to the pressure tank and that has a check-valve, pressure gauge, pressure switch, tank drain valve, main shutoff valve, and over-pressure relief valve. The assembly looks like the following once assembled (note: check-valve not shown in this setup).

You will have to consult the manufacturer's spec sheets to see if it comes with an integral pressure switch. Even if the manufacturer won't respond, often they have spec sheets and manuals available online that will give you this info.

Note: the bottom pump is a no-brand Chinese manufacture pump, you might be able to trace it through Ali-Baba, but you'll have to take the Amazon description's word for what it does as there's not much else available about it online.
