A pump can take up to 4 Steam Engine or 2 Combustion Engines burning oil or 1 Combustion Engine burning fuel without causing an explosion, if you want to drain/collect liquids at a fast rate, use the Energy Link. Combustion Engines will fill a single block of Gold Waterproof Pipe per revolution. Steam Engines will fill a single block of Stone Waterproof Pipe per revolution. When pumping oil that is surrounded by water, it is wise to have two tanks, one for oil, one for water, or the water will get stuck in the pipe and no more oil will enter. Pumps actually take from more than just directly around them. You can hook up a pump over a large 1-deep pool of water and it will never run out.

They will send the liquid they collect straight through any waterproof pipes connected to them. Pumps do not need Wooden Pipes to retrieve liquid from them.

Pumps are the only machines that can be powered by Redstone Engines efficiently. Pumps require Steam Engines or better to power them properly, or 2+ Redstone Engines connected directly to the Pump to work at a reduced rate. They were first introduced in Buildcraft version 2.2.0. Pumps are used to collect Oil, water and lava, and transport it into Tanks or directly into Combustion Engines.
