Summary

Description
English: A hand drawn schematic of a coil pump. The schematic was based on the image at http://www.fao.org/docrep/010/ah810e/AH810E06.htm .Perhaps that the next version of the image is best no longer see-trough; instead the backside and sides should be hidden entirely by a orange color.
