The Zerex website (now owned by Valvoline) states :
"For the cooling system, antifreeze manufacturers recommend changing the coolant
once a year, and some service manuals stipulate flushing and refilling the
radiator every 24 months, regardless of mileage. "

I couldn't find any mention of the old water pump lubricant, which I suspect
means they dropped that product from the Zerex line.
