RPS44

Refiner Packing Set

John Crane RPS44 is a packing designed for paper refiners. Made from expanded PTFE (with encapsulated graphite) and polyamide yarns, this packing is designed to handle high axial and radial shaft movement. In addition to paper refiners, this packing works extremely well on agitators, mixer, and hydropulpers. The resiliency of this packing, made possible by the addition of internally braided rubber cords, allows for increased sealability on rotating equipment with excessive shaft run-out.
