HP Rotary Shaft Seals, the secret is in the housing
We are continuing our “one month, one seal” initiative. In previous posts we talked about the universal nature of O-rings, cord-ring and its tailor-made cut, quad-rings and their four support points… However, there is still much to say in relation to seals, and this time we are going to address the seal which is capable of withstanding the most adverse conditions: rotary shaft seals, more, specifically, HP (high-pressure) rotary shaft seals.
So what do these deals have that the others don´t? What sets them apart from the rest is their composition. HP rotary shaft seals are composed of an SS304 or SS316 stainless steel housing and a white PTFE FDA or a black PTFE/Fiberglass/MoS2 lip. Moreover, these seals feature a fluoroelastomer (Viton®) reinforcement.
Indeed, HP rotary shaft seals are high-performance rotating seals used in a wide range of sectors such as mechanical engineering and the chemical industry for use in centrifuges, pumps, mixers, compressors and gearboxes. Here are some of the advantages of using this type of seal:
- A reduction in the risk of corrosion due to the housing.
- An excellent seal for use in high temperatures, speeds and/or pressures and with corrosive liquids and gases.
- Efficient in situations of poor lubrication and dry conditions.
These are the characteristics which make HP seals an excellent seal for use in high temperatures, speeds and/or pressures and with corrosive liquids and gases. Furthermore, they work efficiently in cases of poor lubrication and even in dry conditions. If you are in doubt, consult the HP seal technical data sheet:
Material | Pressure | Temperature | Speed | Video |
PTFE FDA+INOX304 PTFE/FIBERGLASS/MOS2+INOX304 | ≤25 Bars | -90 to +250 ºC | ≤45 m/s |
