Technical questions
A mechanical seal is a sealing device designed to prevent leakage of a fluid (liquid or gas) between two machine parts in relative motion, typically between a rotating shaft and the stationary housing of the machine.
Its most common and critical application is in pumps, compressors, agitators, and industrial reactors.
A mechanical seal typically consists of the following main parts:
- Rotating face: Rotates with the machine shaft
- Stationary face: Remains fixed in the housing
- Spring: Maintains pressure between the faces
- Elastomers: Provide secondary sealing
- Seat: Seal contact surface
To choose a mechanical seal correctly, you should consider variables such as fluid type, temperature, pressure, shaft speed, and material compatibility.
It's also important to check dimensions, equipment type, and actual operating conditions.
A single-spring seal is a conventional seal made of individual components that's installed directly on the shaft.
A cartridge seal has all its components pre-assembled into a single unit, which makes installation easier, improves fit precision, and reduces errors in the field.
The elastomer should be selected based on its chemical compatibility with the process fluid and the operating temperature range.
Our technical team evaluates these variables to recommend the right option for your application.
The service life of a mechanical seal depends directly on pump maintenance and operating conditions.
In practice, the mechanical seal should be inspected, repaired, or replaced whenever the pump undergoes maintenance, since it is a critical part of the sealing system.
Mechanical seal maintenance includes:
- Regular visual inspection to detect leaks
- Checking operating temperature
- Review of the lubrication or cooling system
- Replacement of worn components according to specifications
- Cleaning and inspection during scheduled shutdowns
If there's a leak, we recommend safely shutting down the equipment and inspecting the seal to determine whether wear, installation, or operating conditions are the cause.
Our technical team can help you diagnose the problem and recommend a repair or replacement.
