The Graco 257435 Ram, Pneumatic (55 Gallon) is an air-powered ram assembly engineered to provide consistent material feed from standard 55-gallon drums. Designed for demanding industrial dispensing and transfer applications, this ram system applies controlled downward force to the platen, helping pumps efficiently move thick adhesives, sealants, mastics, lubricants, and other high-viscosity materials while minimizing waste and air entrapment.
