Guardian Condensate Return

Guardian condensate return pumps quickly collect and return condensate back to a boiler feed unit. The pump action is controlled by either a float switch (simplex) or a mechanical alternator (duplex) designed to energize the pump motor when liquid levels get too high. Various sizes of cast iron or carbon steel receivers are available to meet just about any installation requirement.

  • 8,000 to 12,000 sq. ft. EDR or 10–20 gpm
