Hi All,

I'm in the process of rebuilding my V2. It currently has a mechanical seal that runs against the thrust washer (under the impeller). The thrust washer has some minor wear marks where the previous seal ran so I would prefer to run a twin lip, but dont want to go backwards in terms of sealing ability.

Most repair kits seem to use a PTFE coated twin lip viton seal, is this better than the mechanical seal (or not as good)?

Are they interchangeable i.e. if i have a mechanical seal to i have to stick with a mechanical replacement?

Finally I marked the impeller against the shaft when i removed it but the marks rubbed of after i cleaned it . Does it have to be pressed on in the same position or will i have to get it ballanced in its new position on the shaft?

I dont intend on running more than 12 psi boost but want as much reliability as possible.

Thanks in advance from the land of OZ
