Type HR5 seals are outside mounted balanced seal, which require no shaft or sleeve step for balancing.

HR5 seal shows good performance in high vacuum conditions. Since no auxiliary equipments are needed for installation, it is very cost effective & economical.

These seal can be easily installed & repaired in the field to minimized replacement costs & downtime.

Main features of the HR5 dry running seals are:

• Simple, rugged drive design that withstands shaft movement vibration & deflection.
• Seal design eliminates the need of auxiliary equipments for cooling & lubrications for mixer application.
• It eliminates the possibility of product contamination, since there is no use of barrier fluid.
• Can be used in high vacuum applications. These seals are very cost effective. Seals with bearing can be provided for vessels having greater misalignments with special arrangement.
