Project Description
RTM7N
EagleBurgmann type M7N series Replacement
Wave Spring, O-ring pusher mechanical seal Type RTM7N is a robust and highly interchangeable seals. Used in the different media conditions due to extend material options. It is ideal for use in paper industry, textile printing, chemical petroleum, shipbuilding and sewage treatment industry.
Features
Wave Spring, O-ring pusher construction
Transmission by Pin and groove，independent of direction of rotation
Solid seal faces material are easily interchangeable. Good heat dissipation
Low risk of clogging in solids content or viscous liquids
Can meet two standard dimensions when change in stationary seat
Recommended Applications
Paper and textile printing industry, petrochemical industry and sewage treatment industry
Low solids content or viscous media
