Chesterton is the world leader in split mechanical seal technology. Our innovative split seals have been used to seal thousands of process-critical pieces of rotating equipment with exceptional results and many years of leak-free operations.
Chesterton was the first company to offer a commercially-viable split mechanical seal 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.)
