How to Eliminate Human Error When Selecting & Installing Seals

Mechanical seals are used in pump systems to assist in connecting the systems. This prevents leaking of the pushed product and controls pressure, and excludes contaminants. Most contemporary pump systems shift toward mechanical seals than conventional pump packing. Although there are many benefits to adopting the mechanical approach, it does have certain drawbacks. Here are some of the ways to prevent such errors.

Choose the Correct Seal

A lack of expertise and information hampers the choosing of seals. Consider the application and typical operating circumstances and any possible off-design use before selecting a seal. Selecting a pneumatic seal to function in hot water may seem simple since the medium is not especially challenging.

Properly Install the Seal

Most individuals make the crucial mistake of choosing the wrong seal for the application before installation. Seals can be categorized into many distinct types; therefore, before making your choice, examine your typical operating circumstances, machine setup, and non-process activities like cleaning and flushing. You also should consult pneumatic Seals suppliers in Dubai to help in selecting one.

Once you have chosen the right seal, keep in mind, they require a properly controlled environment to function properly. This starts with properly installing the seals to perfectly align the seal faces, maintain contact, and have adequate lubricant and cooling systems in place.

Prevent Excess Heat Generation

Excessive heat production between seal faces reduces seal life dramatically. The most frequent sign of this problem is dry running. It usually happens when a pump is flooded, and the seal chamber is improperly ventilated before it starts. Other factors may also contribute to excessive heat production and dry running.

A mechanical seal is often the first apparent failure site. However, the underlying reason may be in another section of the system. Before buying the seal, engage pneumatic Seals Suppliers about everything, you should know.

Maintain Proper Storage Conditions

Mechanical seals are made up of several different components made from various materials. Therefore, it is critical to understand how long a seal may be securely kept without affecting performance.

Improper Operation and Maintenance

Once you fit the seal, keep a few things in mind throughout the operation to prevent inflicting any extra harm. Starting the pump incorrectly may cause the motor to trip and the shaft to twist. The internal components will come into contact due to the orbital movement. This results in seal failure and bearing wear. 

Allowing the pump to run empty may also harm mechanical seals, resulting in heat shock and near-instant breaking. A coordinated flush design is essential when using mechanical seals. Contaminants accumulate without a flush plan, producing excessive heat and seal degradation.

If you want to keep a new seal for less than two years, keep it in a clean, cold environment. Rotate the seal faces against each other by rotating the sleeve or shaft two revolutions every three months. If the seal is not in use during that period to prevent face, lock and loss of face flatness.

To prevent the possible problems outlined above, get help from your trusted pneumatic seals suppliers in Dubai in choosing the right seal and advice on the best operating and installation procedures.
