Pulsafeeder Digital Glycol Feeder, Single-Loop, Prewired, 1.5 GPM

The Pulsafeeder DGF1BBABCAB is a prewired, fully assembled single-loop Digital Glycol Feeder designed to maintain consistent operating pressure in closed hydronic systems. The system automatically feeds glycol solution from a 55-gallon tank to compensate for system losses, ensuring stable loop performance. A NEMA 4X control enclosure with an 8-bit microcontroller provides precise pump control, LED status indicators, HOA functionality, an audible alarm, and a single dry-contact output for external notification. The low-pressure switch enables activation at reduced system pressures, making this configuration ideal for low-head or specialty closed-loop applications. The 1.50 GPM gear pump and complete suction and discharge assemblies deliver reliable, long-term operation.
