Technical Trend of Mechanical Seals for Pulp & Paper Plants -The Cartridge Outside Mounted Mechanical Seal-

摘要

A mechanical seal prevents or reduces outboard leakage of toxic chemicals and saves energy and resources.Therefore,it can be deemed as one of the important environmental instruments that is directly and indirectly contributing environmental preservation.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.In recent years,a mechanical seal has been selected as a standard sealing device for such pumps.Accordingly,ease of maintenance and foolproof design are getting of the essence.Anther interest is interchangeability that cuts down spare needs.A new outside mounted cartridge seal having such features is presented.
