Mechanical face seal/floating seal is specifically utilized in extreme hard condition such as dust,sand,mud,rock,chemicals.It can protect the equipment to work in the adverse conditions.
This type is different from the shape of standard floating seal,it uses the trapezoid elastomeric ring,and it is limited in the axial direction when it is applied on machinery.
To choose different elastomeric ring materials are available for any sealing problems:
Nitrile(NBR) is suitable for the temperature from -20ºC to 100ºC.it is compatible with many mineral lubricant oils,NBR can offer the maximum abrasive resistance and corrosive substances,and the pressure can be reached 400 Kpa.
HNBR is suitable for the temperature from -40ºC to 135ºC,the abrasive resistance is better than NBR,it is used specifically for low temperature application.
FKM is suitable for the temperature from -7ºC to 160ºC,it is used for extremely high temperate application.
VMQ is suitable for the temperature from -55ºC to 150ºC,it is used for the low temperature application,but the abrasive resistance is inferior than NBR.
We can follow clients' requests to design all kinds of different items, and we also promise to offer the high quality products and best service to our clients.
