150 General Purpose Single Seal

This seal is a value leader in its class

The 150 is designed for baseline applications and for upgrading packed or component-sealed equipment. The cartridge design eliminates installation error, delivering higher reliability and improved housekeeping.

When packed equipment can’t deliver the life cycle expected in a sealing solution, the 150 mechanical seal will increase reliability and address housekeeping concerns associated with packing.

When component seals are used, the 150 cartridge design will improve the seal replacement process by making it easier and faster while eliminating installation error that is commonly associated with component seals.

250 General Purpose Dual Seal

This dual seal is a value leader in its class 

The 250 is designed for cost effective upgrading from packing and under performing single seals, further increasing plant reliability. The 250 is an ideal choice for baseline applications where the need for special alloys doesn’t exist.

The off-set gland design is very efficient in barrier fluid exchange when compared to most other cartridge seals in its class. This design has improved heat removal. Seal face geometrics are optimized to ensure reliable sealing under varying temperature and pressure changes.

S10 High Performance Single Cassette Seal

Unique a modular cassette that combines advanced seal technology with flexibility in maintenance and repair

In the Streamline series of seals, all the wearing parts are contained in a single replaceable cassette unit. Single and dual cassettes share a common universal gland. Repair becomes a matter of exchanging cassettes making it faster and easier, while significantly reducing cost associated with repair.

S20 High Performance Dual Cassette Seal

Uses a modular cassette that combines advanced seal technology with flexibility in maintenance and repair

In the Streamline series of seals, all the wearing parts are contained in a single replaceable cassette unit. Single and dual cassettes share a common universal gland. Repair is a matter of exchanging cassettes making it fast and easy, while significantly reducing cost associated with repair.

The S20 Streamline seal incorporates Chesterton advanced seal technology into the cassette feature. The in-series orientated seal face design with independently mounted springs, delivers a higher pressure tandem deign. Geometric balance with low heat generation is achieved with the innovative piston design. The two-step installation is made possible with the innovative swing tabs. The S20 utilizes a high flow pumping device, which assists in efficient heat removal.

442 Split Mechanical Seal

Eliminates the need for equipment disassembly during seal installation and reduces maintenance costs

The 442 split seal is ideal for equipment that is difficult and time consuming to disassemble such as large pumps, vertical pumps and horizontal split case pumps. This proven, compact design can be used in a wide variety of equipment and process materials.

The patented high performance split technology allows the 442 to operate from vacuum to high pressures. Its compact design allows for easy installation and cost effective field repair. Split, low cost repair kits reduce ongoing maintenance costs even further. Designed with the installer in mind, the ball-and-socket O-rings provide a quick and easy leak-free seal, without the use of adhesives. Captive screws cannot fall out, making installation straightforward and reliable.

SpiralTrac™ Environmental Controllers

Environmental Controllers have revolutionized the sealing environment in stuffing boxes

When used with Chesterton mechanical seals to reduce the flush fluid required and further enhance seal reliability by driving seal cavity circulation and solids removal.

Improving seal reliability and contributing to production efficiencies

There is a SpiralTrac™ Environmental controller for every application, from split designs, designed specifically for the 442 split seal, to solid stainless steel designs for conventional cartridge seal installations. SpiralTrac™ environmental controllers can also be designed for specific stuffing box/back cover arrangements.
