I am going with that the water pump itself is not going to rupture you internal fresh water plumbing lines. I have a 5.7GPM Shure-Flo that delivers 65 PSI. It has never entered my mind that the PEX system on our motorhome would be compromised. I have been using the pump for 8 years and so far so good.
I will always use a regulator if the water pressure is sufficient to push a stream of water across the street!
Better safe than sorry but I don't always use a pressure regulator.
