Sink pump

[windcree]

I just purchased a Pearson 28 from 1975. And believe it or not my only problem is the galley sink pump. The seals are all dried out. Does anyone have any ideas of were I might get new pump seals for it? On the pump body it has the name TOPSIDER.

What does it look like?
My manual lift pump I believe has leather seals, if you pull a vacuum on it and prime the pump, that wets the seals and it works fine until they dry out again, we never use the pump in our application its a back up.
Sort of a PIA to use too, if I were to use a manual, I believe I would go to a foot pump
