Oring in Bearing Isolators for Pumps
Oring in Bearing Isolators for Pumps
(OP)
Hi,
Please share some light on the usage of twin O-rings in bearing isolators/ Inpro seal for pump bearing housing.
The standard design is one O-ring in rotating member.Is it possible to have 2 O-rings in rotating member?.
What would be its Pros & Cons. considering that already single O-ring is able to do the job of sealing.
Thanks...

RE: Oring in Bearing Isolators for Pumps
Inpro also have an O ring between the static and rotating parts (in their Vbxxd model), that is supposed to help seal it vapor tight when stationary (there has been some disagreement on the long term effectiveness of this however). Is it possible you are referring to this O ring ?
