Type 5625/5625P

Universal Cartridge Seal Family — Dual Cartridge Metal Bellows Seal

The 5600 Series is the first truly universal cartridge seal — and the modular family concept of John Crane's Universal Cartridge will change your approach to sealing. Since the 5600 Series' components are interchangeable, you can apply one seal family throughout your plant. This gives you the flexibility to cover more applications with less inventory, which means your maintenance is simplified, downtime is reduced, plant operating efficiency is increased and costs are lowered. The 5625 and 5625P cartridge seals are available with either Alloy 20 or Alloy C-276 bellows in either a rotating or stationary arrangement. The seal is ANSI and DIN pump compliant. Tangential inlet and outlets. Optimized pressure balanced design. Primary and mating ring reverse balanced designs allow for ID and OD pressure which permits the dual seal to operate as tandem or double and maintains positive seal face closing forces in upset pressure reversal situation.
