Common Applications

Drum Pump for Firestop Materials and High-Volume Sealant Application

The AST SP-55-FS is a high-volume drum pump system built for dispensing firestop sealants and mortars directly from 55-gallon drums. Designed for demanding jobsites and large-scale firestop installation, it delivers consistent, high-pressure output for efficient application of UL-classified materials. With flow rates up to 2 gallons per minute and support for viscous or fiber-filled compounds, the SP-55-FS is ideal for crews handling large quantities of firestop product across multi-penetration or continuous sealant application scenarios.

Common firestop dispensing applications include:

  • Sealing wall and floor penetrations with UL-classified firestop sealants
  • Applying fire caulk or mortar in dynamic and static construction areas
  • Backfilling oversized annular spaces with pumpable firestop materials
  • Firestop installation in multi-zone, multi-penetration, or high-traffic facilities
  • Continuous firestop sealing with drum-based dispensing equipment
