1995 Powersurvivor 80 seal repair kit

[OJJJ]

I have a 1995 PowerSurvivor-80 water maker, serial number LM10189. The original documentation I have on board states the repair seal kit is part number 5-155-03 but this must be an outdated part number and I don’t know the modern equivalent. Is anyone able to confirm what the correct repair seal kit would be for this unit?

The water maker is fully functional but does leak around the rod seal and I would like to rebuild the pump.

Thanks in advance!

I sent the same information to Katadyn support. We'll see if they reply.
