尽管其外观上看是有个管道从边上吸入液体，但实际上入水泵必须浸没于液体中，因为它移除的是直接位于其图形上方的液体，并且在整个 2×2 图格空间中均匀地移除。类似地，出水泵直接在其图形上方生成液体，并且在整个 2×2 图格空间中均匀地生成。
- 单路电线最多可以连接 5 个入水泵和 5 个出水泵。流体输送速度会随之提升，而无须额外的电线作为“管道”。
- 如果将超过 5 个入水泵连接到超过 5 个出水泵，那么沿着电线距离电源最近的 5 个入水泵会将液体输送至沿电线距离电源最近的 5 个出水泵。
- It is possible to place a liquid sensor directly under the outlet pump and connect it in such a way so that the water coming from the pump activates the sensor, which then activates the pump, which then activates the sensor, and so on. This causes the pumps to continue indefinitely, until the inlet pump runs out of water, or the outlet pump becomes submerged.
- Assuming the Inlet Pump is fully submerged, Outlet Pumps produce slightly more liquid than the Inlet Pumps take in.
- In 主机版、 前代主机版、和 versions, The Outlet Pump's ability to produce more liquid than an Input Pump takes in can be exploited in multiple ways:
- Tanks of liquid can be created by repeatedly sending liquids through a pump system. Only enough liquid to submerge the Inlet Pump is required, and any extra liquid produced from the Outlet Pump can be used to fill the tank, providing infinite liquid as long as a separate tank for actually producing the duplicate liquid is maintained.
- Ponds of water, such as fishing ponds, can easily be created using only a small amount of liquid.
- Lava falls can be made by using pumps, which can be used as an NPC-killing device or a means of protecting one's house from enemies.
- While of little use compared to lava falls, aesthetic waterfalls can also be made using Pumps.
- In item form, Pumps have a white rarity and will be destroyed when submerged in lava. While this is not an issue with other liquids, take care to ensure that the pump never becomes unseated while any lava is present, such as by mining the Inlet, or by placing the outlet on a platform (as lava removes all platforms except obsidian). First drain the lava or convert it to solid blocks before attempting to remove the pump.
