Specifying Mechanical Seals

Mechanical seals have become increasingly popular in industry. Many companies develop a set of mechanical seal specifications to make it easier for their people to select one or more seals for an application. The lack of a company specification can cause problems with inventory, installation and interchangeability of seals. Plants are accepting seal components with unidentified materials, making troubleshooting an impossible task for them.


Can the Mechanical Seal be rebuilt?


A good company specification for mechanical seals will include the following:
-- Mechanical Seal materials with the widest range of chemical compatibility.
-- Mechanical Seals that are easy to install.
-- Mechanical Seals with features that make seal repair easy and low cost.
-- Mechanical Seals that require the least amount of inventory and spare parts.
-- Mechanical Seals that operate over a wide range of temperature, pressure and speed, and
-- Mechanical Seal designs that allow the easy conversion of packed pumps to mechanical seals.

A typical plant will use some or perhaps all of the following five types of mechanical seals:

• A single cartridge-mounted balanced seal.
• A dual cartridge-mounted balanced seal.
• A balanced outside seal for low pressure applications.
• A balanced seal installed inside the stuffing box, and
• Metal bellows mechanical seals for chemical and high temperature applications.
