I need to source a small water pump to be used on a linear wear testing machine im designing for a uni project.

It doesnt need a very large flow rate as it only needs to supply a a small amount of water for lubrication.

Can anyone help?

Thanks

why not something used in a fish tank setup? small water flow and cheap.

Yes, fish tank pump would be favourite for pumping small volumes of water.

didnt even think about that! Cheers guys

Screen washer pump or for volume higher flow rate a headlamp washer pump.

Above that you will find pumps for solar system (14mm dia inlet 10mm dia outlet) and caravan water pumps 13" dia inlet and outlet.

The next size up is the eletric water pumps used on Webasco fuel burning heaters.
