China Double Cartridge Mechanical Seal WM208

The China Double Cartridge Mechanical Seal WM208 is an OEM standard dual balanced cartridge seal designed for the severe applications found in the pulp and paper industry and slurry applications. This seal is typically used in pumps for abrasive and environmentally hazardous liquids in cooking, evaporation, and causticizing facilities in pulp mills.

Product Description

China Double Cartridge Mechanical Seal WM208, also referred to as dual cartridge seals WM208, is the answer for applications where the second level of protection is needed due to risks to the environment or operating equipment. Wendong offers a variety of models that are easy to install while also complying with environmental regulations and ANSI standards. A variety of configurations are available depending on the application and operating conditions.

China Double mechanical seals are offered in two arrangements:

Back to back

Two rotating seal rings are arranged to face away from each other. The lubricating film is generated by the barrier fluid. This arrangement is commonly found in the chemical industry. In case of leakage, the barrier liquid penetrates the product.

Face to face

The spring-loaded rotary seal faces are arranged face to face and slide from the opposite direction to one or two stationary seal parts. This is a popular choice for the food industry, particularly for products that tend to stick. In case of leakage, the barrier liquid penetrates the product. If the product is considered “hot”, the barrier liquid acts as a cooling agent for the mechanical seal.
