Features

Unitized construction allows for fast and easy installation and replacement. Design fits DIN24960, ISO 3069 and ANSI B73.1 M-1991 standards.

Innovative bellows design is pressure-supported and will not crease or fold under high pressure.

Non-clogging, single-coil spring keeps seal faces closed and properly tracking during all phases of operation.

Positive drive through interlocking tangs will not slip or break free during upset conditions.

Available in the widest array of material options, including high performance silicon carbides.

Recommended Application

Process Pumps

Other Rotating Equipment

Designed for demanding applications, the Type 2100 mechanical seal is a compact, unitized, single-spring elastomer bellows seal that offers maximum durability and performance.

Ideal for use in centrifugal, rotary and turbine pumps, compressors, chillers and other rotary equipment

How to choose the material of the mechanical seal

The sealing performance and service life of the mechanical seal are related to the material of the zero mechanical seal parts, especially the material of the end seal (friction pair), the material of the auxiliary seal and the material of the spring.

First, the material of the end face sealing friction pair

The friction pair materials include graphite, ceramics, hardfacing alloys, tungsten carbide alloys, SiC, filled polytetrafluoroethylene, tin bronze, steel bonded carbide, stainless steel, phenolic plastic, nylon, and the like. 

Tungsten Carbide Alloy Metal carbides with high hardness and high melting point, such as tungsten carbide and titanium carbide, are formed by powder metallurgy with binder and pressed and sintered. The advantage is that the hardness and strength are very high. Wear resistance, high temperature resistance, corrosion resistance, low coefficient of linear expansion, the disadvantage is that it is brittle and difficult to process. Tungsten carbide is the most widely used end seal material, and is used as a static ring for medium and low speed mechanical seals and a dynamic ring for high speed mechanical seals.
