Penductors, aka eductors, are a great way to vastly improve water flow in your aquarium without adding more pumps or increasing your electricity usage. However, these devices put a lot of pressure on the pump. It is a much better choice to use pressure rated pumps with these devices, otherwise you won’t get as much flow as you’d like. The pressure rated pumps can work when height height is very tall or when there is a lot of pressure built up in the plumbing.
