The Person WP30 / WP30X is usually a portable, gasoline‐driven centrifugal pump used for transferring water.
It is designed for both clean and dirty water use (i.e. can sometimes handle some solids) depending on version. (The WP30X listing advertises “clean/dirty water pump.”)
Common uses include irrigation, dewatering flooded areas, pumping from rivers, ponds, wells, draining swimming pools, or moving water for construction.
