I'll add a few more points here:
1) If you are hearing vibrations throughout the house, I would seriously suspect vibrations as a result of the connections between the pipes and the floor joists. If you can find a way to support your sump piping from the foundation (with, perhaps, insulating supports) I think that will be drastically reduced.
2) If you have to open a valve before the venturi will run (i.e. it is not a fully automatic backup) then be sure to close that valve on the discharge when it is not in operation. If there isn't one already, install a check valve in the line.
3) Leave the battery backup, it's an important part of your system given your high water table. It gives you time to realize there's an issue and turn on your venturi if your main sump dies.
4) Diaphragm pumps are nice, but they are rarely quiet. I don't have much experience with electric diaphragm pumps. The air ones are way too loud. I would suspect that an electric centrifugal pump is much quieter than a diaphragm pump. If you're still in the mood to look around for other solutions. You could try finding a peristaltic pump that fits your flow rate (this is also a positive displacement pump). Positive displacement pumps are not kinetic energy pumps like the centrifugal ones, they move water up by displacing volume. This is both good and bad. It is good because if you find one that will pump at your desired flowrate, you don't have to worry about it reaching the destination, it is moved along by the volume of water behind it, so as long as there is water, it will keep moving. This is dangerous, however, because if for some reason your pipes get clogged or a valve is closed, it will continue to pump and build pressure until the pipe bursts or pump ruptures, both very expensive problems. It's up to you if you'd like to search around for these, but I wouldn't recommend it.
5) Don't use a timer. It is a bad idea for a person with your water table. I don't even know if building codes allow it. The only way to increase the time between pump cycles without risking flooding is to increase the size of the sump, or increase the level at which the main sump turns on.
