There are none.

You have several options for "pumping" out materials from chests, but they all require (logically) some kind of power. You could use Engines such as Redstone Engines (redstone), Combustion Engines (oil/fuel), or indeed Steam Engines (steam).

Note that you could also use Electrical Engines (electricity).

But in no way are there any ways to gain items from chests through pipes without any sort of energy related.
