High volume hand pump?

After going through several power outages from different types of storms, my friends, family and neighbors realized that their emergency hand pumps were not adequate to supply the water they needed. Some have small farms (water for animals and gardens) and some have large families. We all have considered backup generators, solar and other means. However, storms can take out a solar system, and if you can’t get gas for the generators like the victims of the hurricane Sandy storm, then you just would be out of luck.

So, any recommendations on a high volume hand pump?

Thank you
