The Heller-Aller Company in Napoleon, Ohio was a leading manufacturer of deep-well windmills. Starting in business in 1886, it lasted -- remarkably-- until the early 1990s. Hitzer Inc. purchased Heller-Aller in 1995, largely for its patented water pumps and continued to manufacture the same efficient hand windmill and pitcher pumps. These quality pumps include deep well hand pumps, windmill pumps, and pitcher pumps. The Heller-Aller hand pumps are still proudly made in the USA by Amish craftsmen.
