What type of pump to use for spraying organic compost tea???

There are two types of pumps: Diaphragm and Centrifugal.

I've done a few searches in Lawnsite, Google, Spraying Companies (selling their own equipment), & Yahoo Compost Forum. And after reading these searches... everyone has a different idea which one is better at protecting microorganisms.

Some like diaphragm pump, but don't like the pressure and it may get plugged up from the compost tea.

Others like centrifugal pump because they pass everything through, but their impellers can hurt microorganism...thus hurting your compost tea.

So who's using what type of pump for spraying compost tea in the field?

And has anyone sent any of the compost tea to get checked after they've ran it though their spraying equipment? Is the microorganism still good?
