They make this confusing and I'm not sure why the model number suggests it's non food grade, but on ProCon's NSF/ANSI 169 listing for Special Purpose Food Equipment they state that all Stainless Steel body rotary vane pumps with model number starting 106 are safe for all food grade applications. There are certain food grade applications where the brass body pumps are not recommended however they are used almost exclusively in dispensing softs drinks and coffee. I'm no expert on food grade but I personally have no concerns about using this pump in a sap RO application.
