The Gusmer GH-2 Proportioner delivers robust hydraulic performance for spray foam applications with up to 28 lb/min flow and 10 kW heater power.
The Gusmer GH-2 Proportioner is engineered for reliability and simplicity in demanding spray-foam installations. Built on the proven Graco Reactor 2
hydraulic chassis, the unit features a 10 kW heater, either 230 V 1-phase or 400 V 3-phase power options, and a high-pressure pump system designed to handle polyurethane materials with a 1:1 mix ratio. Ideal for residential and commercial insulation jobs, such as wall cavity fill, rim joists, roof decks and even concrete lifting, the GH-2 offers a maximum fluid temperature of 190 °F (88 °C) and a max flow rate of 28 lb/min. Service access is simplified via standard off-the-shelf components in the electrical cabinet. With compact dimensions (54″ H × 32″ W × 21″ D) and approx. 585 lb weight, the GH-2 is rugged yet mobile enough for job-site deployment. Whether outfitted with heated hose and whip or integrated into a larger
spray system, the
Gusmer GH-2 Proportioner ensures consistent, high-performance results.
