This wiper is specifically designed for 5-gallon (19–20L) drum systems and ensures a tight seal between the follower plate and material surface, improving pump efficiency and reducing material waste.
The Graco 184420 Wiper is a flat-style sealing component used in ram pump assemblies to maintain consistent pressure and prevent material bypass. It is installed on the follower (ram) plate and moves inside the drum, wiping the container walls clean as material is pumped out.
Its Buna-N rubber construction provides resistance to wear, oils, and common industrial coatings, making it suitable for continuous professional use. This part is considered a critical consumable in fluid handling systems, as it directly impacts pumping efficiency and material cleanliness.
