7 Types of Mechanical Seals for Centrifugal Pumps

Types of Mechanical Seal in Centrifugal Pump Applications and Their Structural Differences

Mechanical seal types used in centrifugal pumps are specifically designed to accommodate continuous rotation, axial movement, and stable pressure conditions while under continuous operation. The most common centrifugal pump seal types are: Component seal(s), Cartridge seal(s), Balanced seal designs, and Unbalanced seal designs . Material used and configuration of seal face play very important roles in performance consistency.

Advantages Types of Mechanical Seal in Centrifugal Pump

Clear Structural Classification

Different Configurations of Mechanical Seals Allow to Address Varietal Sealing Challenges

Flexible Seal Selection Options

Provides the Engineer with the Ability to Select the Best Combination of Seal Performance, Cost and Maintenance Needs

Compatibility with Most Standard Pump Designs

The Majority of Mechanical Seal Designs Have Been Developed to Fit a Widely Used Pump Design.

Application Types of Mechanical Seal in Pump

Types of mechanical seals in centrifugal pumps will vary based on operating conditions and system design. For example, standard single and double mechanical seals are the standard and most common seal types installed in centrifugal pumps used to pump clean liquids or similar commercial chemicals. These seals are designed to provide predictable sealing characteristics during the steady state of operation. In addition to providing predictable sealing characteristics standard mechanical seals are widely utilised in chemical processing, energy plants and industrial fluid circulation systems requiring stability.

FAQ

What different kinds of mechanical seals are there available for pumps?

Single seals, double seals, balanced seals and unbalanced seals are the four main types of mechanical seals used in pump applications.

How do I determine which seal type to use?

In selecting a mechanical seal type for a pump, there are three main characteristics that will determine which seal to use: pressure, temperature, and characteristics of the media being pumped (liquid).

Would it be safe to say that a double seal is always better than a single seal?

It would not be safe to say that two seals are always superior to one seal. The right seal type for a pump application will be determined by the application's operational requirements and service conditions.
