This is what I got. the threads from a 32mm(pump) is close enough to make this work. I also put the female end of the 1 inch union into boiling water to expand it slightly. NPT is a taper thread and heating will allow to set down further and seal.
That is BSP (British Pipe Thread) it is not going to work. US is NPT (National Pipe Thread) not the same thread pitch as BSP. That is also Solvent weld metric (slip) to BSP
I am having the same issue as you: Needing a replacement for the Varios 4 starting at the white threads. Can you elaborate more on your solution? Do you use the threaded female side of the union on the male pump threads?
Thanks for the link but what I need is this partMcMaster-Carr

Hope this helps. BTW, I believe most of the 24Vdc and 36Vdc Pumps with the Controller are BSPT, “British Standard Pipe Tread.” You will still need the Gasket, that came with the pump, for a water tight seal.
Thanks Steve! this is exactly what I neededMcMaster-Carr

Looks like the you could use the adapter that steve provided to convert from metric threads to us standard, then it'll fit the standard schedule 40 pipe and fittings commonly available. So convert from metric to standard, then use any standard union you want
