Mechanical seals for K, KM, KML, KMS, BShM, KM35-32-130, KM50-32-125, KM32-22-120 pumps
End seal for pump K, KM, KML, KMS, BShM, KM35-32-130, KM50-32-125, KM32-22-120
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.
Materials of mechanical shaft seals K, KM, KML, KMS, BShM, KM35-32-130, KM50-32-125, KM32-22-120
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 - ceramics
- SIC - silicon carbide
- TC - 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.
