bellow type mechanical seal in stock

A Bellows seal does not have a secondary seal that must move along the shaft or sleeve to maintain seal face contact. The secondary seal is static state at all times, even when the pump is in operation.

Primary seal face wear is typically accommodated by welded metal or elastomeric bellows which move to assist in the compression of the rotary to stationary seal faces.

Bellows seals allow for high and low temperature applications when used in conjunction with metal bellows. They do not require a rotating secondary seal, which means it is not prone to secondary seal hang-up or fretting along the shaft or sleeve.

John Crane brings you the world’s most complete selection of performance-proven edge-welded and formed metal bellows sealing products used in a wide range of rotating equipment such as pumps, compressors, mixers, and agitators. Our experience in diverse industries such as oil & gas, petrochemical, chemical, refrigeration compressor, pharmaceutical, food processing, pulp & paper, and more have proven the soundness of John Crane’s metal bellows design.

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.

In many cases, Cartridge Seals may contain the exact same major items that are sold separately as Component Seals. These pieces include the Rotary Seal and Stationary Face as well as other minor parts like O-rings or Gaskets all required at assembly. The advantage of using a Cartridge Seal is that the time required for installation, and even more importantly, the possibility of error during installation is dramatically reduced. When installing a Cartridge Seal, the necessity of having to measure internal components positioning on the shaft to achieve proper face loading is eliminated. Cartridge Seals come pre-assembled from the factory with all internal components assembled with proper face loading and all pieces in place, exactly where they should be. Cartridge Seals eliminate the need to handle delicate, polished parts such as Seal Faces that can be compromised by the presence of dirt, smudges and oils that can result from handling during assembly. So, for the easiest and most reliable Seal installation, Cartridge Seals go a long way towards helping you achieve trouble free startup and extended service life from your equipment.
