Mechanical sealing adopts the principle of mechanical friction sealing, which has excellent sealing performance, which can effectively prevent leakage and protect the safety of the environment and equipment. Compared with traditional packing seals and rotary seals, the sealing effect of mechanical seals is more reliable.

Our products are made of high quality materials and manufacturing processes, with a long service life and low cost of use. It can effectively reduce the maintenance costs and operating costs of equipment .
Queeny Mechanical Equipment Co., Ltd. is an advanced fluid seal design and manufacturer. Our factory is located in Ningbo, Zhejiang, China. and our sales organization is located in Shanghai. We not only provide customers with products, but also provide customers with overall solutions including services to cope with the complex and challenging working conditions encountered by customers.
The main products we produce are: Component Seals, Dry Gas Seals, Mixer and Agitator Seals, Cartridge Seals, Metal Bellows Seals and Silicon Carbide products. Products are widely used in chemical, textile, food, pharmaceutical, metallurgy, printing and other mechanical equipment fields, and can undertake the design of non-standard and special seals.
PTFE bellow seals are designed for extremely corrosive chemicals, including concentrated acids, salts, strong oxidising & reducing agents, and chemically active organic compounds. All components which come in contact with the liquid being sealed are made of chemically inert material. Metallic components clamping ring and springs are located outside the media. In this seal series Glass filled PTFE face is composite moulded with highly flexible PTFE bellows.
Application
Used in acids, alkalis & extremely corrosive services.
