Our Butyl Brute is a rugged hotmelt applicator system developed specifically to melt and pump high viscosity butyl rubber based sealants. The system is designed for applications involving the assembly of sealed insulating glass units such as windows and doors.

The melt unit features a 15 lb (6.8 kg) capacity tank. The cylindrical design accepts briquette form butyl sealants, which are converted to fluid state and pumped and extruded by an electric motor-driven gear pump through a (HANDGUN) handgun/hose assembly. A rotating chain and scraper in the tank propels the molten butyl sealant to the pump inlet port. A high performance 1/6 hp motor and flow control valve provide a wide range of output control.

Butyl Brute Features:
• All-electric systems available for 115 or 230 V
• Pumps and extrudes high viscosity materials up to 500,000 centipoise
• No compressed air required, eliminating complexities of air operation
• Reliable, smooth-output, positive displacement V4 gear pump
• Pump warmup thermostat protects pump and motor during system startup
• Tank gun/hose temperatures independently controlled
• Over-temperature protection if tank thermostat fails
• Pump output easily adjusts by turning external knob on flow control valve
• Rugged sheet metal enclosure
• Switched handgun assembly decreases pump/motor ware and increases service life
