Rubber Bellow Seals, specifically designed for water pumps, play a crucial role in wastewater treatment plants, especially in sewage processes. Their compact design allows for easy mounting, offering convenience for various installations within this sector. Notably, these seals feature a distinctive rubber bellow secondary seal, providing significant axial flexibility to protect the shaft or sleeve from fretting and wear in challenging operational conditions.

The versatility of Rubber Bellow Mechanical Seals stands out, allowing their use regardless of the direction of rotation. Unlike traditional seals, the driving torque is not transmitted through the coil spring, ensuring reliable operation. Instead, the necessary driving torque is facilitated through the spring and spring holder. Additionally, the incorporation of a single coil spring serves to prevent the ingress of effluent particles, thereby enhancing the seal’s durability and performance in wastewater applications. This feature is particularly beneficial in maintaining the effectiveness of the seals in demanding and abrasive environments.
