If you are trying to make a simple pump as a demonstration consider making an "Impulse or Inertial" pump. These are used as sample pumps in the environmental industry.
This is nothing more than a lenght of tubing with a ball check at one end. The end with the ball check is submerged into the water (usally down a shallow well) . The tubing is then moved up and down quickly. On the down stroke water is forced past the check. On the up stroke the water is trapped as the check valve seats.
You can fabricate one with some small pipe fittings and a marble if it really must be "home brewed" but a check valve is cheap enough.

What kind? A gear pump? Centriugal pump? Reciprocating? Turbo?
What application is it for? Volume? Flow rate? Material requirements? Cost requirements?
Will an aquarium pump work, or maybe a car's oil or coolant pump? This is waaay too general to even begin to answer.

I would start by determining the properties of the fluid. Most importantly, is it compressible or incompressible, liquid or gaseous? Is it viscous? What is its vapor pressure at the working temperature? What flow rate do you require. How much pressure will you need? Only after you completely understand what you wish to accomplish should you attempt to select, locate, and purchase a suitable pump.

Either a piston or a turbo pump. Buy it. It'll be a lot cheaper than building one from scratch.
