Are you sure the pump is bad?

Can you get the pump out of the lamp? Can you open it enough to see the impeller? Does the impeller move? Freely? Can you put power to the pump and see the impeller spinning?

If the impeller is doing its job, then it is more likely you need to inspect and clear/replace some or all of the tubing. If someone used the wrong kind of oil in the lamp the plumbing could be blocked.

If the impeller is not doing its job you should take the pump to your local garden supply. No your local big-box, but a local garden supply or nursery that has parts for fountains. Many of the smaller fountain pumps will work with some fiddling around to get the connections just right. Use vinyl tubing if you have to add anything to the system.

Make sure you use mineral oil in the system, or rain lamp fluid if you can find it.

DO NOT use essential or fragrance oils in the system because they will make the oil go gummy and you will be replacing your pump again in short order.

And takes lots of pictures of the process, please! There are many people who have rain lamps but don't want to try and repair them because of the scarcity of information.
