Parmax1 is NOT pressure limited.
Parmax 1 Pressure Limited, is!

Nice labeling huh?
I bought the wrong one too...

 Hi Folks- I found that my fresh water pump was running continuously
 today and not pressurizing the system and not cutting out when
 pressurized.  I confirmed there was water in the tanks and flow to the
 manifold that controls tank choice.  But there was no water in the filter
 after the manifold and before the pump.  I removed the hose connecting the
 manifold/filter to the pump and when I sucked on it, I got water, so
 nothing appears blocked.  When I turned the pump on (Par-Max4), I could not
 feel any suction on the opening.  I presume these are self-priming pumps,
 so I should have felt some pull.  The pump is 30 years old, so I am
 presuming it is just dead, but wondering if there is any other scenario
 that might make it not work before I replace it.  Thanks- Dave

Classic pressure switch problem.  I wasted countless hours an $$$ with Jabsco 
pumps.  Recommend you try a different manufacture.  Many cheaper, more reliable 
options on Amazon.

Did you liberally purge it?  If it has any air in it, it will continue to run.  
Run several gallons through it and then check it.

Barring that, the pressure switch may need adjusting.
