Rubber Bellows Mechanical Seal WM208

The China rubber bellows mechanical seal WM208 is designed as a dual-pressurized (double) seal but incorporates a patented double-balance feature which also allows it to be used as an unpressurized (tandem) dual seal arrangement.

Product Description

China rubber bellows mechanical seal solutions are widely regarded and trustworthy by consumers and may meet continually modifying financial and social requirements for ceramic mechanical seal, double cartridge mechanical seal.

Our business has already set up a professional, creative and responsible workforce to develop purchasers together with the multi-win principle.

China rubber bellows mechanical seal WM208 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.

Features of China rubber bellows mechanical seal WM208
