Project Description
RTM3N
EagleBurgmann type M3N（DIN24960）series Replacement
Type RTM3N With reliable performance, wide range of applications and easy installation features. Used in the different media conditions due to extend material options. RTM3N is conical spring and O-ring pusher construction mechanical seals,designed for large batch production. It is ideal for use 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
Dimensional data conform with DIN24960 standard
Recommended Applications
Paper and sugar industry,Food Processing,waste water technology
