What small pump to use with new releaser?

[ClarkFarmMapleSyrup]

I just won the bid on a Milk releaser. Its like one of the big Benders, and the seller is selling another onw supposidly just like it. What pump would any of you "bender users" recomend? I was thinking about a Gast, but what do you all run. There will not be more than 50 taps on it, maybe less than 30, so what should I use?
Thanks, and I will post pics of it when I get it.

It is this one http://www.ebay.com/itm/BENDER-MILKING-MACHINE-UNIT-WASHER-GOOD-CONDITION-/120901589376?pt=LH_DefaultDomain_0&hash=item1c264bd980#ht_500wt_689

Clarkfarm find yourself a small dairy pump and be sure the regulator works as these units do not like to operate beyond 18" vac. Being that your only running 50 or so taps your lines would be extremely leak free. Good luck.
