Mechanical seals are an essential part of many industrial and commercial applications, so ensuring you are working with the best seal for your pump equipment is critical. Just as important is selecting the right manufacturers.

When assessing the best mechanical seal manufacturers, there are several significant factors to consider.

Here’s what to look for in a mechanical seal manufacturer.


The right seal manufacturer will have a reputation for designing well-crafted equipment that will keep your operations working optimally with no threat of leakage or malfunction.

Their long-term performance can often be influenced by application and installation. When they’re well maintained, mechanical seals should operate reliably for years. The seal’s design and construction must withstand standard environments for prolonged periods.

Selecting a reliable seal manufacturer for your application can ensure extended optimal performance and save you maintenance time and money.

Wide Selection

A manufacturer may boast top-rated equipment, but if it doesn’t work for your specific applications, it doesn’t matter. The top manufacturer will have a wide selection of mechanical seals of different types and sizes to suit your application’s needs.

There are a wide range of mechanical seals available for use in a variety of different operations, so choosing the right seal depends on factors such as the fluid or material being transferred, operating conditions including pressure and temperature, and more. The best manufacturer will be able to supply the exact seal for your specific needs.

Industry Requirements & Standards

Mechanical seals are vital components in the safe and efficient transfer of fluids, and just as important is ensuring your equipment can meet the strict requirements set by the industry.

For example, the largest U.S. trade association for the oil and natural gas industry, the American Petroleum Institute (API) specifies strict qualification testing, safety, and design specifications for mechanical seals, stipulated in API Standard 682. This is utilized to measure the quality of seals across many other industries, for a wide range of applications and associated equipment.

When selecting seal equipment manufacturers, make sure that they actually test against industry standards rather than simply design to fit the equipment. AESSEAL, in particular, is a leading seal manufacturer that complies with all of the specification and testing requirements when API 682 seal is required.

By ensuring all your seals are up to the highest industry standard, your operation can run safely and effectively for as long as possible.

Locations & Customer Service

Finding the right seal manufacturer doesn’t just come down to the quality of their equipment, but availability, aftermarket support, and customer service. These considerations can have a big impact overall—especially if you experience installation issues or seal malfunctions.

Being able to contact a manufacturer for technical assistance or operational advice can be invaluable to keeping everything running smoothly.
