Description：
This seal is to replace AES DMSF seal. In this seal's name，DMSF represents Double Monolithic Stationary Flow which perfectly summarises its features.
Features：
•Monolithic Seal Faces & Industry leading modular design
•Double Hydraulically Balanced Seal Faces
•World-leading barrier fluid pumping and seal face cooling technologies
• Increase equipment uptime and lower maintainance costs
• Perfectly withstand barrier and process pressure fluctuations
• Patented design
Advantages：
•Monolithic Seal Faces to reduce distortations under high or low temperatures
•Industry leading modular design to decrease maintainance costs and improve plant uptime
•Double Hydraulically Balanced Seal Faces to ensure minimal seal face distortion & help to guarantee stable fluid film conditions between the seal faces
•Finite Element Analysis method used to ensure Reliable Face Drive Mechanism
•All outboard seal faces are thin-faced to minimize heat generation
• Ideal for applications that demand an external forced circulation device
Background Knowledge：
What kind of problems does the solid particle impurity media pose to mechanical seals?
With the development of modern industries, especially oil and gas field development, mining, metallurgy, electric power, papermaking, fine chemicals, salt chemicals, water supply and drainage, sewage treatment, food processing, and other industries, more and more pumps are used to transport solid particles.
Fluid medium containing solid particles and fibers is very unfavorable to the operation of the mechanical seal of the pump. When the solid particles in the fluid medium enter the end faces of the friction pairs of the mechanical seal, wear and leakage of the sealing surfaces will be aggravated. The solid particles deposited around the mechanical seal can also interfere with the function of the seal and cause the seal to fail. Similarly, fibrous substances entering the end faces of the seal will also cause serious leakage of the seal.
