Flowserve Pac-Seal Type 51 Manuel d'utilisateur télécharger pdf (Page 2)

Description

The Pac-Seal Types 51 and 52 are similar to the Types 21 and 31 in

design, with a crimped head and hex-torque drive system but with a

more exible bellows. The convolution in the seal bellows allows for

greater axial movement and shaft deection than Types 21 and 31. This

adds exibility but reduces pressure capability. Both Types 51 and 52 are

available in double seal congurations and balanced versions.
