The R-ZF cartridge seal is a series of single seals that do not require external cooling. The seal has no moving parts on the shaft, so it can be installed directly on the shaft, without an additional sleeve. The springs are reliably isolated from the product, which prevents clogging. R-ZF is a reliable, economical and durable seal designed for the paper industry.
Application: Suitable for Ahlstrom / APP / Sulzer / ABS Scan without additional pump modification
