mechanical seals Roper Pump

1) Standard Mechanical Seal (Type 21)
Mechanical seals are for those applications where product leakage is unacceptable. The mechanical seal uses less power than the packed box and, under proper conditions, has a longer service life. It does not require adjustment. Our standard mechanical seal is an elastomeric bellows type seal, with a temperature limit of 212ºF (100ºC). Special fi tting is available for higher temperature applications.

2) Positive Driven Mechanical Seal (Type 8-1 & Type 9)
These are positive driven seals with a PTFE wedge, for use where corrosive and/or viscous liquids are being processed. Wedge construction of the secondary sealing element virtually eliminates leakage. These seals have a temperature limit of 450°F (232°C). Special fi tting is available for higher temperature applications.
