Suitable pump for vacuum filtration?

Hello I am trying to build an economical form of vacuum filtration and now I have gotten as far as enquiring a vacuum pump for my setup witch consists of a 1l vacuum filtering flask, rubber stopper and a buchner funnel.

So i Wonder if anyone here has some experience whit vacuum filtration and migth help me out.

Btw would this pump be strong enough to use for my purpuses?

I don't think that would work very well at really low pressures but yes, that would work if you don't care about how fast your filtering goes. Another option that is much more economical would be a water aspirator. You can also get hand pumps at some places but they usually aren't that good.
