Mechanical seal optimization
Thread Content
This device treats wastewater with a salt concentration of 35% and a temperature of 120°. Mechanical seals generally start to leak after about 15 days of use; the pump is a chemical centrifugal pump. What type of mechanical seal should be chosen to solve this issue?
Consult the manufacturers of mechanical seals; they are quite professional
It’s necessary to find out what is causing the leakage – whether it’s due to leaks in the rotating and stationary rings, the O-rings, or scaling. What auxiliary solutions? It is recommended to use a 32-pulse scheme with clean, cool water or saltwater of low concentration.
There are corrosion-resistant machine seals; PLAN62 could be considered for the flushing scheme

First, analyze the cause of the leakage: is it overheating, corrosion, or impurities? Then propose solutions to the problems
Solid content of the material? The service life of the mechanical seal is short now; what is the problem?
Check your mechanical seal to identify where the leakage is occurring; only after determining the cause can it be ascertained whether the issue lies in a deficiency in a certain component of the mechanical seal or is caused by some other factor. What is the type of pump? What is the pressure at the pump inlet and outlet during multiple sweeps? Determine the pressure in the sealing chamber to determine whether it is a problem with the design of the mechanical seal structure. The properties of the medium – is it corrosive? Will the salt content in your wastewater cause crystallization? Crystallization has a very negative effect; you need to add auxiliary systems to prevent it. There are other reasons as well, such as the motor, whether the couplings are aligned, the level of vibration in the pump, and whether there is cavitation, etc. Please check carefully.
