A diaphragm pump should work well. I haven't seen one I can afford, even used. I wanted a diaphragm pump at the time, what I bought was an impeller pump that had deceptive specifications, and it does not pump particles as large as it claimed. It does very well at pumping "clean" pc but something like a window from an envelope will clog it. Taking it apart, cleaning it out, and reassembling it takes ten to fifteen minutes and that adds up when you have to do it several times a day.
Renting a diaphragm pump cost effectively would require a lot of work done in a short time, constant mixing and pumping. Even then the pump is going to be sitting there idle 85% of the time. If the budget allows, buying a diaphragm pump with the idea of eventually selling it at a small loss could be an option. Then one might not feel pressed to work long hours constantly to justify rental.
Pumps take most of the work out of papercrete, making it into a one woman job.
