Default Piston pump ro oil

I have a older coster ro machine with a magikist piston pump. I want to change the oil in the pump magikist told me any sae 30 oil is fine. I would like to use food grade oil just in case some were to leak out through seals. Has anyone with a piston pump already found a source for food grade oil?

There are two sets of seals between the gear box and the pistons. I just run non detergent 30# in mine.

Doesn't one seal the crank case one seal the pump head with a piston rod between the two? I don't think there can be a transfer of liquids.
