If you're not even an engineering student, you are going to go through hell trying to understand any definition of a pump curve I can pass on to you, but here goes:

A "pump curve" is, in reality, a Pump Performance Curve. This curve is a plot of the flowrates a centrifugal pump can deliver at a variety of total developed heads. What it tells you is the flowrate that corresponds to a given total developed head. It also plots the efficiency of the centrifugal pump at a given point, the developed brake horsepower, and the Net Positive Suction Head (NPSHr) required at that flowrate point.

Now, you're probably worse off than you started out at, since you probably don't know what the above terms all mean and what their significance is. Don't be embarrassed; many engineers also don't know. To understand and know these terms requires several courses in Fluid Mechanics plus some years of hands-on engineering in the field. We certainly can't cover or make up for that in one forum thread.

I recommend you get in touch with Aurora Pumps - if they are still in operation - and ask them for a copy of the pump you presently have. You'll need to identify the model and serial number in order for them to help out. I've used many of their pumps in the past and I think the one you have is a turbine regenerative type, which is a small flow- high head pump.

I hope this information helps you obtain what you are looking for.

Some 5 minutes of searching on the web gave the following result: http://www.aurorapum...ves_340_360.pdf
Your curve is on page 35 (=catalog page 432), the upper graph, curve for impeller diameter 8.75"
