Other links look good.
A peristaltic pump seems the way to go.
However, consider the possibility of an aquarium pump intended for 
mains 50 Hz Ac operation with a pulsed supply. I haven't yet tried 
this but will be doing so 'in the next while" for an application I 
have. For a one off a COTS unit may be best for you but the aquarium 
pump has the advantage of availability and (fwiw) probably of cost.
