A.W. Chesterton Company, which has multiple locations throughout North America, has introduced their latest mechanical seal innovation – the Chesterton 250L Cartridge Double Seal with features that aim to simplify mechanical seal installation. The new 250L uses Chesterton’s double seal designs with the addition of a clamp lock ring that allows for single screw tightening. The seal also has internal centering clips which do not require removal.
The 250L cartridge double seal is designed to fit ANSI pumps used in lower-duty chemical processes such as ethanol grain processing. The 250 double seal is designed to provide sealing security that conventional single seals cannot match. A durable back-up seal aims to provide the opportunity for scheduled maintenance to avoid unplanned downtime and production losses.
