Calefactio GMP6 is economical yet rugged, compact and easy to use fluid feeders for small closed-loop systems. Their function is to automatically supply pressurized water or a water/glycol mixture to a closed-loop space heating, chilled water, snowmelt, solar, radiant heating or process control system, to ensure that minimum system pressure levels are maintained.

• Prevent major floods - In the event of a major system leak, only the content of the storage tank will be pumped into the system.
• No direct connection to potable water supply - Eliminates the need for backflow prevention devices
• Provide leak detection - Dropping solution level in the storage tank warns of developing system leak.
• Easy maintenance - Just pour back in the liquid drained for maintenance.
• By-pass valve - Used to set prv pressure and for manual agitation of solution
• Rugged self priming pump - Can run dry for extended periods and be used to fill your system. Its components are chemical resistant and certified to meet UL and CSA norms.
• 120 Vac/1 ph/60 Hz, standard plug with 6 ft (1.8 m) cord.
• Level float switch with piggyback plug / Level switch stops the pump if fluid level in the tank is too low
• Easy to adjust PRV to maintain system pressure (up to 60 psig (413 kPa) and 100 psig (690 kPa) for solar systems).
