Project Description
RTBT-RN
EagleBurgmann BT-RN series Replacement
RTBT-RN is conical spring and O-ring pusher construction mechanical seals,designed for large batch production. This type of mechanical seal is easy to install. covers a wide range of applications and reliable performance. It is widely used in paper industry,sugar industry, chemical and petroleum, food processing, sewage treatment industry.
Features
Conical spring,unbalanced,O-ring pusher construction
Torque transmission via conical spring, independent of direction of rotation
Wide option in seal face material
Spring with deep coils to reduce the risk of clogging in solids content or viscous liquids
