Wendong is China best rubber bellow seal suppliers. The offered products are widely acknowledged for their fine finish, accurate dimensions, durability, anti-corrosion, and capacity to bear high temperature. Our rubber bellow mechanical seal WM21 is highly durable and corrosion-resistant as well. Due to the compact design, our standard mechanical seals eliminate the requirement of extra radial and axial space in their installation. Furthermore, we also offer a customized range of these products in order to fulfill the specific demands of our clients.
1. Low cost.
It is probably the largest mass-produced seal in the world.
2. No sliding elastomer or O-ring.
Nothing to “hang up” on the shaft.
3. Easy to install.
There are seldom any measurements to make or set screws to tighten to the shaft. Most designs are positioned against a shaft shoulder, or attached to a shoulder cast into the back of the impeller. Push it on the shoulder, and that is all there is to it!
You can purchase these seals from a variety of manufacturers, distributors, and bearing houses. Most distributors have replacement charts that will reference your present seal and recommend an equivalent design.
5. No shaft or sleeve fretting.
When installed properly, the seal cannot frett or damage a shaft or sleeve because there is no relative movement between the rubber boot and shaft or sleeve.
