Jeff, some of your questions can be answered on the post titled "Mini Bulk Plumbing Question". I see you already commented there, but still have questions.
Before our Mini Bulk Tank arrived, we drew from drums using the skid pump and multi tap on the skid.
Lots of guys have a floor or wall mounted pump just for transfer to skid tanks, saving the skid pump for daily use on job sites.
We got an airflow chemical pump from Grainger that runs on a pancake air compressor. It draws and sends at about 15 gal. per minute.
