CAST IRON AT SUB ZERO TEMPERATURES
CAST IRON AT SUB ZERO TEMPERATURES
(OP)
would be cast iron PUMP(gg-20)able to stand lower temperatures?
The pump is going to be installed outside and the temperature could be up to minus 30 deg.C.

Still, for cast iron, if only to protect one's investment, I would winterize it - or else go to DI or something.

the flow is 500 l/h
and its grey cast iron , grade gg-20.
the pump will be cover with some type of insulation.

For me, the rule has always been for cast iron no more than 100 psi or so pressure, ambient service, no thermal shocks.
It's like putting a glass and putting it on the stove. Heat it slowly and you might be ok. Anything goes wrong, it cracks.

Low temperature piping will impose thermal expansion / contraction loads (forces)on the pump nozzles.
