442M Mixer Split Seal
The Chesterton 442M Split Mixer Seal has been designed from the ground-up to be the benchmark for split seal performance in mixing and agitating equipment.
Large radial motion capability
Mixers and agitators are known for having large shaft runout during operation. This is why conventional pump seals are not well suited for these services. The 442M split mixer seal is specifically designed to reliably perform in those services which routinely exhibit large amounts of radial shaft runout. Large internal clearances allow radial shaft movement without damaging seal components.
Patented Automatic Centering
Maximum radial runout performance demands perfect centering. Unique centering "buttons" positively center the gland about the rotating element.This ensures maximum radial travel in all directions.
Face “Wiping” minimized
In rotating narrow face designs, if the equipment shaft is not concentric to the stuffing box bore, particles are prevented from being transported across seal face wear track due to the wiping action created. This protects the lapped seal faces from damage.
