dry runing mechanical seals

Advantages

• Available as components or as cartridge units

• Suitable for pressure reversals

• Due to the hydraulic conditions, product pressure as well overlaying barrier pressure closes the seal

• Friction-locked connection to the shaft

• Connections for steel (SeccoMix 481) and glass-lined (SeccoMix 461) reactors are available to DIN 28138 standards or as required

• Available also for lateral drives, please inquire

• ATEX certification available on request
