Spray Foam Feed Systems
The incoming feed system supplies the isocyanate and resin components from bulk containers to your proportioner. Once the materials are heated and pressurized, the outgoing feed system delivers properly proportioned materials to your spray gun through heated hoses.
Material Mixing system
Some but not all spray foam materials will require mixing. Graco's Twistork Helix Mixer is designed with patented, helix-shaped mixing blades. Its gentle mixing action reduces fluid degradation and splashing compared to propeller blades. Mounts through the bung opening of the drum head.
Incoming feed system
Typical spray foam applications use stick or diaphragm pumps to supply bulk materials to the proportioner. The type and size of supply pump depends on the type of material you are spraying and equipment flow rates. Material manufacturers will recommend a type of pump needed to supply their material.
Outgoing feed system
Heated hoses are used during the spray foam process to maintain material temperatures between the proportioner and the spray gun. Heated hose lengths can be up to 400 feet (122 meters) long, therefore, it is necessary to keep the material heated as it travels through the hose out to the spray gun. Maintaining temperatures helps to ensure proper mix and ratios at the point of application.
