100fps/30m/S John Crane Seals SiC Carbon Cartridge Mechanical Seal For Andritz Sulzer Pumps
Double-acting Cartridge Seal for Heavy Equipment
The SAF is a double-acting seal particularly engineered to suit pumps, screens, knotters, sorters and pulpers in heavy process industries where liquids containing solid particles and impurities are involved. Seal design can be multi-component or cartridge version, depending on application. Size range varies from 0.787'' to 17.716''/20mm to 450mm.
Typical OEM designs include brands: Andritz, Beloit, Bird, GL&V, IMPCO, Netsch Mohno, Noss, Voith, Toscotec,SSP Pumps, Sulzer Pumps, Sunds Defibrator and Warman Pumps, etc.
Design is unaffected by pressure changes. The Type SAF seal is double-balanced, which makes the construction fully independent of pressure changes in both process and barrier fluid. It's designed for minimum damage risk — the rugged construction for all applications prevents failure and provides long and trouble-free service. Type SAF seal provides easy installation and low maintenance costs. Ultimate reliability for screen sealing requirements. It is recommended to use Safeunit™ (plan 54) for seal water control.
