The Cartridge Mechanical Seal for Pulp & Paper Plants

Abstract

In a pulp & paper plant, many numbers of varieties of pumps are utilized such as water pumps, pulp pumps and chemical pumps all through the production processes from digesting to painting. Recently, a mechanical seal has been selected as a standard sealing device for such pumps. A cartridge seal is coming into wide use for work improvement, for being easy to handle and for installing correctly. And then the cartridge seal is used not only non-flushing use but non-cooling use in a plant. Additionally, the cartridge seal with emergency seal is developed for pulp pumps. When a mechanical seal doesn’t work and leakage starts, the emergency seal installed in the cartridge seal works and can use for a certain period. I will introduce the latest technology trend about the cartridge mechanical seal for the pulp & paper plant.
