Type SSB1M is a stationary mounted, multispring, balanced seal supplied as a standard cartridge assembly. A key feature of Type SSB1M is that the springs are stationary and located outside the process fluid. They are therefore protected from clogging by dirty and fibrous products. The construction means that as faces  wear the  PTFE slot ring (which replaces the traditional O-ring preventing hang-up and O-ring ‘rolling’) moves onto a clean part of the primary ring housing, reducing the risk of hang up caused by dirty or crystallising products.

The standard rotating seat is a shrunk-in silicon carbide, the standard primary ring is carbon or silicon carbide shrunk into stainless steel (a hard face option of tungsten carbide is available).

Typical applications

  Type SSB1M is a single cartridge seal for use with clean fluids and low consistency slurries and abrasives: e.g., water, solvents, and paper stock (consistency<2%). It is used  in pumps in the paper industry and general industry applications such as water  and desalination processes. Type SSB1M cartridge seal  fits in various pumps as well as other  industry specific process equipment. Type SSB1M seal is versatile, easy to install  and maintain.

 Features

The balanced cartridge design  makes Type SSB1M seal applicable for a wide range of demanding conditions.

1. Seal faces are installed using a heat shrink process ensuring correct, distortion-free face alignment at all recommended temperatures.

2. The springs are located in the stationary body of the seal which reduces the risk of the springs becoming clogged. Shaft misalignment does not vibrate or wear out the O-rings.

3. PTFE slot rings replace the traditional O-rings in places where they are exposed to the product, preventing sticking. 

4. Protected faces, the seal face carriers are driven by machined fits, preventing metal stress from distorting the face.
