A mechanical seal is a crucial component used to create a fluid-tight barrier between two moving surfaces, typically in equipment with rotating shafts like pumps or mixers. it works by preventing fluid from escaping during operation. The seal consists of two faces, either flat or curved, that are pressed together by a spring to maintain the seal along the shaft.
One face of the mechanical seal is attached to the rotating shaft, while the other is fixed in the housing. As the shaft rotates, the two faces remain in contact, ensuring a secure seal that prevents fluid leakage. These faces are commonly made from durable materials like ceramic, carbon, or silicon carbide, and are encased in metal for added stability.

Here are answers to some common questions our clients, particularly those in industrial sectors across the Middle East and North Africa, often ask.
A mechanical seal works by creating a fluid-tight barrier between a rotating shaft and a stationary housing using two sealing faces pressed together. One face rotates with the shaft, while the other remains fixed. This contact prevents fluid leakage, even under high speeds and pressures.
The main types of mechanical seals include:
Rubber bellow mechanical seals
Conical spring mechanical seals
Cartridge mechanical seals
Metal bellow mechanical seals
External mechanical seals
API 682 seals for industrial applications
Mixer and special application mechanical seals
Mechanical seals are made from a combination of high-quality materials:
Sealing faces: ceramic, silicon carbide, carbon
Elastomer components: EPDM, Viton, NBR
Metal parts: stainless steel, corrosion-resistant alloys
The choice of materials depends on the operating conditions – temperature, pressure, and type of fluid.
When selecting a mechanical seal, it is important to consider the following factors:
Type of fluid (chemical aggressiveness, viscosity)
Operating temperature and pressure
Shaft rotation speed
Installation orientation and position
Specific industry requirements (e.g., food, pharmaceutical, petrochemical)
The lifespan of a mechanical seal depends on operating conditions, material quality, and proper installation. Under ideal conditions, it can last between 1 and 5 years, and with regular maintenance, even longer. Harsh working conditions can significantly shorten its lifespan.
The most common causes of mechanical seal failure are:
Improper installation
Dry running without lubrication fluid
Excessive axial loads or vibrations
Using unsuitable materials for the specific fluid
Dirt buildup or abrasive particles between the sealing faces
Regular maintenance and proper installation significantly extend the seal’s operational life.
