The Chesterton® 442C™ Cartridge Split Mechanical Seal is the latest innovation in split seal technology, combining superior seal performance with the ease of installation of a cartridge split seal.

Chesterton was the first company to offer commercially-viable split seals for plant-wide use, which revolutionized pump sealing across industries. Since that time, we've launched a number of innovative split seal designs now used as a standard by companies around the globe. We offer shaft diameters ranging from 25-914 mm (1-36 in.)

A mechanical seal is a device used to contain fluid within a vessel where a rotating shaft passes through housing, or sometimes where housing rotates around a shaft. These vessels are usually pumps, mixers, agitators, etc. The mechanical seal's purpose is to allow the shaft to rotate freely without allowing large amounts of fluid to escape.

Flexaseal Engineered Seals and Systems, LLC. CHOOSING THE RIGHT SPLIT CARTRIDGE MECHANICAL SEAL | 2. INTRODUCTION. Mechanical seals are a common.

Split Seals, If your facility utilizes large pumps and rotating equipment and the reliability and efficiency of your plant, performance are top of mind, split seals are the answer. John Crane

This type of seal comes in two separate pieces, as shown at right. Unlike ordinary cartridge mechanical seals, these two pieces can be installed 

Split Seals - Single and Double Designs Radially split seals allow for easy installation of mechanical seals on double ended pumps and larger pieces of equipment which are generally labor intensive when installing non-split seals.

Browse John Crane split seals, including o-ring seals, elastomer bellow seals and mixer seals. John Crane is an American company, now a subsidiary of Smiths Group and provider of engineered products and services including mechanical seals, couplings, hydro-dynamic bearings, seal support systems, filtration systems and artificial lift.

New patented technology takes split seals into challenging applications. Standard seal fits ANSI, stock/slurry, and split case pumps and mixer/agitators.

Split Mechanical Seals are designed for the equipment where dismantling & assembly of the machine is difficult job. Split seal is a unique design with minimum components for assembling the seal and allow user to install the seal in minimum time.The multi spring design keeps the faces in uniform contact.
