The Glycol Make-up Unit GF60 (GMU) automated 110V diaphragm pump with digital control is designed to maintain critical minimum pressure levels to make up for losses that may occur due to leakage. The automated system operates as needed to add water or water-glycol solution to a closed -loop heating, chilled water, process, snowmelt or radiant heat system. The unit can handle output pressures from 7.5 to 70 psi and has a self-priming pump.
