Grundfos Variable Speed pumps are designed to pump
liquids compatible with their cast iron pump housing
construction. They are recommended for use in closed
hydronic systems.
Grundfos Variable Speed pumps
are for Indoor Use Only.
Grundfos Variable Speed Pumps are intended for use
with water, or a 50/50 mixture by weight of propylene
glycol.
