Do you mean if the sink had a hand-pumped drain? Or do you mean for supply? Well.... here are my thoughts on both.
For water supply, I really do like foot pumps, and really don't like hand pumps. On two boats I've used the same pump, which is the Whale Gusher Galley, like so:
It's not that big in real life ;)
Typically just the foot pedal and part of the "stalk" protrude and the rest is inside a cabinet. I've used these "full time" and been very happy with them. They pump on both the up and the down stroke do can deliver a lot of water (4gpm). I've used hand pumps and not liked them so much, and likewise a "tip-toe" pump... ugh, that was a pain (it's a foot pump that recesses into the sole and then you can pop it up to use it).
There is a situation in which I could perhaps see using a different foot pump, and that is if you have smaller boat, maybe are only aboard part time, and you have a very small water supply tank. I say that because the Galley Gusher does deliver a lot of water, and although you can "feather" it, it's still easy to get a slug of water. In that case I might use something like a Baby Whale. It only delivers on the "push," 2.2 gpm, and would be a pain for regular usage; but might be the ticket for a weekender with a 15- gallon water tank.
I had one of the above pumps in the head, and it was a perfectly pleasant pump to use, for an area where you don't need (or want to use) larger quantities of water. Nice on bare feet too :)
As for grey water pumpage, the boat I was referring to had manual pumps to drain both the head and galley sinks (the builder was one of those "no through hulls!" people and thus the whole 32-foot boat only had three below the waterline (engine intake, head intake, head exhaust). If it were only for that reason, I would just put in a good seacock, have the galley sink self-draining and be done with it; but for the wonder that is a good, deep galley sink, I would go with the alternate pump/drain method.
Okay, so back to the setup: The sinks just drained into hoses that were connected to the cockpit drains (which drained out at the transom above the static waterline). The pump part of it was great, but it did not have any sort of sump, and that was sort of a pain as the sink would fill with water quickly. Since it was already set up, I added a much larger diameter initial drain hose as part of another project, and that almost acted as a sump; if I were setting it up from scratch I would either use a real sump (box), or if it were convenient maybe a longer run of large-diameter hose (would have to think about that).
Behind and beside both the galley and head sinks were small lockers that held the pumps, which were simply Whale Gusher Urchin type pumps, mounted vertically (pump body at 6 o'clock; pump handle end at Noon), and you would pull the handle in an out/down motion to pump them. Let me see if I can find a photo. Okay, here you can see the basic idea: The bilge pump is inside that little locker just to the right of the sink that has the stained-glass door. I'm not sure I'd do a swinging door again, since it can get in the way if you are pumping in a seaway (you only have one hand, the door swings and hits your arm, etc.). Of course there would be ways around that with a different style door, no door, a magnetic latch to hold it open, or whatever.
Unfortunately I don't seem to have any with the door open, to show the pump. Here is one other one though. You can see the small door again where the pump lives. The range would normally be to the right but it was temporarily removed for project maneuvering space.
This was taken during the aforementioned slight re-model where a bit more "drain hose storage volume" was added. The story is that originally there were two tiny, shallow "doll house" sinks side by side in the galley. I could see those would be a barrel of laughs for daily use. So the project was to add a larger, deeper sink (was about 9" x 13" x 9" deep - commonly available marine one). That went in the prime location. Then, in place of a second sink (and instead of just filling it in flat), one of the "dollhouse" sinks was re-installed a slight bit further to the right. You can see where I was adding a new divider piece since the division was shifted right. The second sink was not plumbed up for a supply line, but just a drain (connected to main drain via "dishwasher" fitting). It functioned as a super-secure, really handy dish drainer (and/or secure stowage). I would definitely do that again as it worked really well.
