APPLICATION
Foundry Sand Mold & Core Compaction
The KT-2BAR delivers 1,240 BPM with a deep 4-inch stroke to compact green sand, resin sand, and core mixtures evenly inside foundry flasks. Its lightweight 7.4 lb frame gives bench molders the precision needed to pack sand tightly into complex patterns without damaging delicate mold details.
Casting Cylinders & Sleeve Ramming
Engineered for metal casting facilities, this pneumatic bench tamper packs refractory materials and sand firmly into cylindrical sleeves and casting tubes. The consistent air-powered impact eliminates hidden voids and porosity to ensure smooth, high-integrity metal pours.
Refractory Lining & Crucible Maintenance
Ideal for furnace and ladle upkeep, the tool efficiently packs dense castable refractories, plastic clay mixes, and patching compounds into melting crucibles. Industrial maintenance crews rely on its focused impact energy to achieve uniform refractory density for extended furnace life.
Benchtop Soil & Concrete Sample Compaction
Materials testing labs and civil contractors use this air tamper to pack soil samples, test cylinders, and concrete test molds under controlled conditions. The optional KT-XTH extension pipe assembly allows operators to adapt the tool quickly for deeper bench molds and varied workstation heights.
FREQUENTLY ASKED QUESTIONS (FAQ)
What size air compressor is required to run the KT-2BAR Bench Rammer?
The tool requires an air compressor delivering at least 15.8 CFM at 90 PSI through a standard 1/2-inch NPT air connection.
What is the recommended operating pressure (PSI)?
Operate the rammer at 90 PSI (6 bar) for optimal compacting force. Do not exceed the 100 PSI (7 bar) maximum limit to prevent internal seal damage and premature wear.
Can this bench rammer be converted for stand-up use?
Yes, you can add the optional KT-XTH Extension Pipe/Handle Assembly to extend the reach of the tool for deeper molds or standing operations.
How do I maintain and lubricate the KT-2BAR?
Add a few drops of air tool oil directly into the 1/2-inch air inlet daily before each shift to protect internal seals, the cylinder, and the piston. Always disconnect and bleed the air supply line before servicing the tool or changing tamping butts.
