Typical application

Type SSB2M is a dual cartridge seal.  Its double-balanced design  ensures the reliability and longevity of the seal in the most demanding conditions. Type SSB2M seal is ideal for use with fibrous and abrasive fluids, most often used  in pumps in pulp mills, minerals processing and other  slurry duties  up to 40% solids by weight and a solids hardness of 8 Mohs. Type SSB2M seal is widely used  with other  process equipment including agitators.

Features

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 in barrier fluid. The barrier fluid washes the springs, preventing process chemical corrosion and 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.

5. double-balanced design  allows the use of both pressurised and un-pressurised barrier fluid and prevents face overload.

6. Type SSB2M Series seals will accept ± 0.08''/2.03  mm axial movement (shaft end play) during normal operation due to their piston design.  Impeller adjustments do not affect face load or spring force.
