silicone mechanical seal ring parts for water pump
silicone mechanical seal ring parts for water pump
is the most versatile friction material in mechanical seals.It has strong chemical resistance performance, high mechanical strength, good wear resistance, high temperature resistance, good self-lubrication, light weight, low coefficient of thermal expansion, high hardness, good dimensionality at extremely high temperatures , strong corrosion resistance and high elastic modulus, long service life and other characteristics.Applicable to the production of various mechanical rings,bearings,bushings and other friction meterials.Sic mechanical seal are widely used in petroleum,electric power,light industry,aerospace,automotive,paper and sewage treatment,chemical pump and its rotary machinery and other fields,and paired with carbon graphite,sic mechanical seal has the smallest friction coefficient,it can be used as a high-parameter mechanical seal.
