High-Output Pneumatic Drum Pump for Firestop Sealants (HG 350H-FS)

Drum Pump for Firestop Materials – High-Output 55-Gallon Pneumatic System

The HG 350H-FS is a high-output pneumatic drum pump engineered for dispensing firestop sealants and mortars from 55-gallon drums. Built with a powerful 35:1 pump and capable of flow rates up to 3.25 gallons per minute, this system is ideal for large-scale firestop installation across multi-penetration, high-traffic, or continuous sealing applications. Its all-air operation, extended hose compatibility, and support for UL-classified materials make it a trusted solution for demanding jobsites and industrial environments.

Common firestop applications include:

• Sealing wall and slab penetrations with UL-classified firestop sealants
• Applying fire caulk or mortar over long linear joints or deep openings
• Backfilling annular spaces with fiber-filled or high-viscosity materials
• Firestop installation in hospitals, data centers, and commercial high-rises
• Continuous sealing in new construction, retrofits, and multi-zone projects
