Features

Dynamic o-ring does not slide against metal gland, preventing fretting damage
As stationary face wears, clean area of face advances underneath o-ring, resisting hang-up from product deposits
Monolithic face design eliminates distortions of face flatness common with pressed designs.
Stationary coil springs located outside the product. Coil springs accommodate equipment axial movement
Stationary spring design resists centrifugal forces and self-aligns the seal faces to account for angular misalignment
Standard tangential flushing provides an optimized flow path for enhanced cooling and cleaning of the seal faces
Unique centering buttons make seal installation easy, removing the additional step of setting clip removal
Unique centering buttons also serve as indicator for excessive axial movement
Cartridge assembly is preset, eliminating installation error
Cartridge design also prevents the fretting of any pump parts
