Not sure about the high pressure ,as I use flat plates, but I would assume
it is because of the extremely high stagnation temps. What does the
manufacturer say?
As for charge pump, you could use a progressive cavity, ' carbonator pump'.

Subject: [RE-wrenches] Apricus SHW Charging
I am reviewing the commissioning instructions for the Apricus solar
DHW system. I note that the specified charging pressure for the
glycol loop is 72.5 psi per the manual. This seems high compared to
other systems I have experience with. Can anyone comment on
1) The science behind the high system charging pressure and
2) an off the shelf pump you use to achieve these pressures
