Please help identify this pond filter

[mikel]

Hello,

I have a KOI pond that came together with the house. It looks like there is an issue with pond filter valve head. There are no labels on the filter. The person who bult the pond and installed the equipment is not accessible. Maybe someone can recognize this filter? Any idea about the brand and model?
White PVC fittings covered by tape are not part of the filter. Previous owner put some red labels on the valve head.

It must be more than 10 years old. It still mostly works fine, but the white/yellow gasket-like thing inside the valve head is partially damaged and it seems to affect water flow somehow. I dropped some of the water plant media (feels like small gravel or coarse sand) into the pond. It got sucked into the filter and no I see these sand-like particles embedded into the gasket material destroying it. I was hoping to replace that gasket or the whole valve head if possible instead of buying a new filter.

Looks like a bead filter, but no idea what brand/model. Are there no markings on it at all? Not even on the bottom?

I see a place for a square label on a side. Maybe there was a label there at some time, but not anymore.
On the metal ring that attaches valve head to the filter body there is some label, but it is not readable. I see a warning message in English there. Advice to read the manual. Also something in French. Barely readable model number 32165-4089 (Rev.2)
Actually, I just did a google search for that model number and "32165" returns some Sta-Rite / Pentair filters. They look different, but after additional searching for Sta-Rite parts I see pictures of filter valve heads that look just like mine.

I think it is a Pentair / Sta-Rite Cristal-Flo (Gen 1 ) filter and the valve head is WC112-148.
I ordered the top part. Hopefully it fits.
