    Introduce:
    Fenghua Bohong Seals Factory is a large-scale Limited Partnership Company. Our company covers 3000 sqm, and is located in Feng hua Ning bo, Zhejiang Province. We are only 20 kilometers away from the Lishe international Airport and 30 kilometers from an export harbor - Beilun port. Due to these convenient transportation factors, We can offer products rapidly to buyers.

    Our company is specialized in the production of SIC rings, SIC bearings,Seal faces and so on. The SIC products are in conformity with the standards of DIN24960, ISO3069 and GB6556. The products are widely used in large fields, such as petroleum, chemical industry, mechanical metallurgy, dyeing, food, pharmacy, automobile, water supply and drainage for city. We can design, measure and make the non-standard and special seals.

    The best price, timely delivery, perfect quality and excellent service are also provided for our customers abroad.

    Welcome to send drawings or samples to us, we always guarantee to supply the full list products andbest service according to the customers'requirements and the pumps' working conditions.

    products below

    1) Reaction bonded (self-combine) SIC
    SIC is mixed up with carbon, according to different particle sizes. SI is involved in the reaction process, during sintering. So, there is about 10% free Silicon present in the SIC RB, which limits its application. This material cannot be used in hydrofluoric acid, strong alkali and oxidizing medium, and it's max working temperature is 1200.
    2) Self sintered pressure less SIC (SSIC)
    Pure SIC powder and a little additives are molded into different shapes, which are then sent to the sintering process under 2000 to 2300. The purity of SSIC products is above 98%, and the max. Working temperature up to 1600. SSIC is chemically inert to almost all kinds of acids, alkali, and strong oxidizing medium. So it's an excellent heat resistance, wear resistance and corrosion resistance ceramic material.
    3) SIC with 5 - 30% graphite content
    With the evolving technology, the regular SIC material cannot meet the demand of high PV value applications. So the company developed a new grade of material - graphite loaded SIC (with 5 - 30% graphite content), which increases the self-lubrication and thermal conduction of the material. This material is also featured by low coefficient of friction and improved coefficient of thermal expansion. So it in a way combines the advantage of SIC and carbon.
    4) SIC with controlled porosity
    A very thin liquid film is to be maintained between the seal faces, to ensure smooth operation of the mechanical seals and a long seal life. The brand new grade of SSIC - SIC with controlled porosity - is to make 2 - 12% porosity (holes) on the SSIC seal face. These holes are in the size of 50 to200 micron met
