Downloads: Installation Instructions

As with any rubber / silicone hose below waterline, the PSS PRO bellow must be inspected on a regular basis for any signs of wear, aging or chemical deterioration. PYI suggests preventative maintenance with a precautionary replacement recommendation in 8-10 year intervals. During bellow replacement it is recommended that the o-rings & set screws in the stainless steel rotor also be replaced.

FAQ

What general maintenance should I be considering for a PSS PRO Shaft Seal that is working perfectly well with no apparent issues?

PYI recommends that the bellows be replaced once every 8-10 years with the PSS PRO Shaft Seal. During bellows replacement it is also recommended that the o-rings & set screws in the stainless steel rotor are replaced, as well as the hose clamps. Under most circumstances the carbon stator and the stainless steel rotor will not need replaced.


Can I re-use my set screws when making an adjustment or removing the PSS Shaft Seal?

PSS set screws

No, please be sure to never use the same set screw on the shaft twice. There are two set screws in each of the two holes in the stainless steel rotor. One is tightened onto the shaft and the other is tightened onto the first to lock it in place against the shaft. The set screws are made with a cup at the base that compresses into the shaft ensuring a secure grip. PYI's PSS Maintenance Kit comes with five new set screws included. When re-installing the rotor please use new set screws. In the case that you do not have spare set screws, the set screws in the rotor need to be reversed so there is an unused cup being compressed onto the shaft.
