That should be no problem at all for that filter. I have had smaller eheims at a greater head height than that. As far as flow rate, I think it is rated for around 270, but always take that with a grain of salt. Depending on what you put in the filter, how long it goes between cleaning, etc, the flow rate will vary greatly. A good rule of thumb is pretty much to take the rated tank size for a given filter and divide it by two. If you are close on that then it should be adequately sized. I would think the 2073 would be acceptable on a tank up to 55 gal.
