Portable 5-Gallon Pump System for Refractory Repair (AST SP-5-RR)

Easy-to-Use Dispensing System for Pumpable Refractory Materials in 5-Gallon Pails

The AST SP-5-RR is a rugged, industrial-grade portable pumping system engineered for the precise and efficient delivery of pumpable refractory materials directly from standard 5-gallon pails. Built on a compact wheeled frame for easy mobility, this pneumatic system is ideal for field service, furnace repair, and plant maintenance crews who need a reliable solution for dispensing thick, fiber-reinforced compounds into confined or vertical spaces.

Its straightforward design allows quick setup and minimal training, enabling crews to perform refractory maintenance without the need for disassembly or heavy manual application.

The Perfect Solution for Refractory Insulation, Patching, and Repair

The SP-5-RR excels in hot spot repairs, void filling, and behind-the-lining applications in environments such as:

• Industrial furnaces and kilns
• Waste heat boilers
• Petrochemical reactors
• Expansion joints and anchor voids
• Glass and steel production lines

Capable of handling high-viscosity materials, it ensures consistent, high-pressure delivery — even in tight, overhead, or hard-to-access spaces. Its lightweight frame and durable wheels make it easy to move between job sites or across plant floors.

The hose length and handle configuration can be customized to fit your needs.
