Tips for Installing Your Mechanical Seals

An important aspect of the design of a gas compressor is the mechanical seal. A mechanical seal minimizes or eliminates the leakage of gas at the interface between a rotating shaft and the stationary housing. Tip #1: Choose the Correct Materials Choose the correct materials of construction for the application.  The materials selected must endure the temperature extremes, pressure differentials and be tolerant of the corrosive process gases of the specific gas compressor application. Additionally, the sealing face materials must have proper resistance to friction, frictional heat and resistance to wear. One of various grades of mechanical carbon are often chosen for the sealing faces Tip #2:  Consider the Form of Lubrication  All friction mechanical seals require some form of lubrication to lubricate, cool and help seal the gases in the gas compressor. Pre-lubing the seal faces and seal cavities will best protect the components during start up and the first moments of operation. Waiting for the lube system to get lubricant to all areas of the seal after start up can have a detrimental effect on the seal's longevity. Tip #3: Check the Spring System The sealing faces of a mechanical seal are pushed together by some form of spring system. Before assembling the seal onto the shaft, confirm that the spring system is freely working, and not hung up, by pressing gently against the primary ring assembly, taking caution to avoid direct contact of the sealing surface with your hand. Tip #4: Make Sure to Install Your Mechanical Seal Correctly This tip is specific to Ro-Flo’s Single Face Mechanical Seal. Specifically, installing the seal onto the sliding vane compressor. Refer to the diagram below for the specific component names. The first step of the installation is sliding the mating ring into place. Due to the o-ring on [...]
