What are the types of cartridge mechanical seal ?
The main cartridge mechanical seal types and characteristics
cartridge mechanical seal is a shaft seal device that integrates all sealing components into one. It can be divided into the following main types based on structural characteristics and application scenarios:
Classified by balance method
Balanced cartridge mechanical seal types
1. Standard cartridge mechanical seal types are usually of a balanced structure, characterized by springs that do not come into contact with the material. The compression of the springs is adjusted by positioning blocks, making them suitable for high-pressure or volatile media scenarios.
2. Balanced design can reduce the specific pressure of the sealing end face, reduce wear, and extend service life.
Classified by structural form
1. Single end cartridge mechanical seal types
The sealing end face is composed of a pair of dynamic and static rings, with a simple structure and low cost, suitable for conventional working conditions with clean and non corrosive media.
2. Double end cartridge mechanical seal types
It contains two sets of sealing end faces and requires injection of sealing fluid with a pressure higher than 0.1MPa of the medium. It has the functions of cooling, lubrication, and sealing, and is suitable for strongly corrosive, high-temperature, particle containing, or flammable and explosive media.

Classified by cooling method
Efficient cooling cartridge mechanical seal types
Innovative design of cavity structure, directly flushing the sides of the moving and stationary rings with coolant, efficiently removing frictional heat, debris, and particles, maintaining the stability of the sealing end face, suitable for high-speed rotating or high heat load equipment.
Classified by installation and functional characteristics
1. Universal cartridge mechanical seal types
It has the characteristics of pre installation, no measurement of sealing length, and adjustable shaft at any time. During installation, only the sealing cover bolts need to be assembled and tightened, with strong interchangeability, which can reduce maintenance costs.
2. Anti rotation positioning type containerized mechanical seal
By fixing the static ring with anti rotation pins to prevent it from rotating with the shaft, the sealing end face is ensured to fit accurately, which is commonly used in centrifugal pumps, reaction vessels and other equipment.
Classified by application scenario
1. cartridge mechanical seal types for pumps
Designed for centrifugal pumps, slurry pumps, etc., it can withstand working conditions such as medium circulation gasification and particle wear. For example, when the double end structure is used for media containing sediment, seal damage can be reduced by controlling the reflux rate.
2. cartridge mechanical seal types for compressors/reactors
Adapting to high-pressure and high-temperature environments, using balanced structures and corrosion-resistant materials such as spring seats and transmission pin components to ensure axial compensation capability and prevent medium leakage.
Summary
The classification of containerized mechanical seals is based on balance methods, structural forms, cooling designs, and application scenarios. Its core advantages lie in integrated installation, high reliability, and adaptability. When selecting, it is necessary to consider the characteristics of the medium (corrosiveness, particle content), operating parameters (pressure, temperature), and equipment type comprehensively.If you want to view other products,pls see this website & www.aefluidtec.com/
