__NOTOC__
The India Mark II and III pumps are considered to be medium-deep pumps, accessing water at a maximum of 50m and 30m, respectively. However, the India Mark II Extra Deep pump can go up to 80 meters, so is considered to be a deep pump. They are all listed here, as they have similar design and maintenance needs.
