Product Description1. Single seal configuration2. Balanced design3. Independent of direction of rotation4. Semi-Cartridge construction5. No dynamic O-ring on the shaft
Technical Features1. O-rings are dynamically loaded to
prevent shaft damage2. Easy and trouble-free installation3. Due to large radial clearance the
damage to the seal faces are avoided, in addition to the seal faces being protected by strong steel parts
4. Misalignment during installation and operations is reduced due to the static springs
