SULZER - mechanical seal

SULZER - mechanical seal

The design of the mechanical seal consists mainly of two parts: a movable part and a fixed part. The fixed part is usually a ring that is fixed in the pump housing. The movable part is mounted on the shaft and is pressed against the fixed part by means of a spring. Mechanical sealing is achieved using secondary seals (bellows, rubber rings) and a friction pair. When choosing a mechanical seal, it is important to choose the material of the secondary seals and friction pairs.

Sulzer Mechanical Shaft Seal Materials

    Rubber material:
  • NBR (nitrile butadiene rubber), temperature resistance -20 to +120C
  • EPDM (ethylene-propylene rubber), temperature resistance -30 to +170C
  • Viton (fluoroelastomer), temperature resistance -30 to +185C
  • PTFE (fluoroplast), temperature resistance -260 to +260C
    Friction pairs
  • SUS - metal (stainless steel)
  • CAR – graphite
  • CER – ceramic
  • SIC – silicon carbide
  • TС – tungsten carbide

It is visually difficult to understand how these materials differ from each other (except for PTFE), so it is easier to choose a material based on the pumped medium and its temperature. Contact us, we will help you determine the material and choose the right mechanical seal for your Sulzer pump.
