Reliable Made in China Double Mechanical Seal Parts and Component Structure Overview

Double mechanical seal parts consist of multiple precision elements that work together reliably to form a comprehensive sealing solution. Common components are primary seals, secondary seal faces, springs or wave springs, secondary sealing elements, metal housing and fasteners for normal shaft alignment. Also, compared to single seals, double mechanical seal configurations use additional elements within the intermediate sealing chamber.

Advantages of Double Mechanical Seal Parts

Modular Component Design

The components within a double mechanical seal can be replaced independently, allowing for the maintenance of individual components rather than replacing the full seal assembly.

Improved Shaft Seal Protection

Double shaft seals provide greater stability of the seal when the shaft experiences either axial or radial motion.

Easier Standardization

Using standard sealed components simplifies both inventory management and maintenance planning in a facility that uses a large quantity of componentry.

Double Mechanical Seal Parts

Applications

Users looking to search for double mechanical seal parts based on either design or components are also searching for double mechanical seals to help them select, maintain and replace components.

Common examples of the types of searches include: 

  • The investigation of double mechanical seals prior to upgrading a current pump or motor
  • The replacement of worn double mechanical seal components while still retaining compatibility with a current design.
  • Learning the proper configuration of double mechanical seals used in some multi-stage or unique shaft applications.
  • Conducting evaluations of each pump to balance pressure temperature and movement in each unit.

In most cases, users are looking for technical information rather than marketing or sales information, therefore it is extremely important that the technical information regarding a double mechanical seal is accurate in terms of the structure of the seal.

FAQ

How should I classify the types of double mechanical seals?

Double mechanical seals are generally classified as follows; based on seal arrangement, seal balance and whether buffer/barrier systems are used.
In general, replacing individual components from a double mechanical seal design is possible as long as they meet the original specifications of the seal.
The term double mechanical shaft seals is more accurately used to define seals that are designed to seal on shafts that have a specific set of load / structural parameters, as opposed to being an entirely new seal type.
