I used to make a living selling capacitors for single stage charge pump
they were tagged with the name voltage doubler.

I'm building a 10 stage charge pump using 400wvdc capacitors rated at
22uf. Running this pump from 220 VAC mains it's taking 3 capacitors for
each stage. Minus losses I should be getting around 3,300 vdc using a
half bridge from the split 220VAC mains here in the USA.

Although google is my friend I can't find much about charge pumps I've
had experience building ladder multipliers I'm just hoping that the
1kPIV diodes will hold up to the task, they are high speed 30amp surge.

You can't find it because you are calling it by the wrong name. Google
"Cockroft-Walton Multiplier" and you will get lots of hits. Here are two
to start you off:
