CARTRIDGE SEALS


A cartridge mechanical seal is an “off-the-shelf”, completely self-contained design requiring no assembly prior to installation. The operating position of the seal faces are preset, eliminating detailed, exacting measurements and possible damage or contamination during the installation process.



CASSETTE SEALS


These high-performance mechanical seals have a unique modular cassette design that combines advanced seal technology with flexibility in maintenance and repair. Both the single and dual tandem seals utilize a common seal gland.

GAS SEALS


Useful in processes that cannot tolerate ANY product contamination or escape into the atmosphere. They are also useful for processes or materials that are sensitive to heat that typical mechanical seal faces generate.



BELLOWS SEALS


Ideal for high temperature and harsh chemical applications where standard elastomers cannot be used effectively. They are an excellent choice for applications where the process fluid is incompatible with common elastomers or where the cost of custom o-rings may be prohibitive.

SLURRY SEALS


Selecting the proper seal for slurries is crucial to avoid clogging that leads to seal failure, reduced asset life and declining productivity. Chesterton has extensive experience providing mechanical seal solutions for a wide variety of tough slurry pump sealing applications.



MIXER & AGITATOR SEALS


Designs with vibration-isolated faces which withstand conditions of drag and shear that destroy common seals. Chesterton’s mixer / agitator seals also offer excellent motion tolerance and instant pressure shift capabilities.

COMPONENT SEALS


Cost-efficient workhorse of many industrial operations. Unlike cartridge seals, component seals require separate assembly of the rotary and stationary parts on the equipment shaft or sleeve. Component seals offer a replaceable, low-cost sealing option, while providing quality and reliability.



SPECIALTY SEALS


A variety of specialty seals designed for specific equipment or those hard-to-seal applications in various industries. These include high viscosity seals, pump specific seals, bearing seals and others.
