Rejuvenating 200 year old ' powerless' pump technology

摘要

The hydraulic ram pump isn't exactly the sort of technology that one could call new. In fact the ram pump is a device that dates back over 200 years to the era of the Montgolfier brothers, famous for their ballooning escapades. Since then, developments in hydraulic ram pumps have been slow. In some respects, the technology has been overshadowed by the widespread proliferation of electric and engine driven pumps. what is more, owing to their conventional design and cast iron construction, traditional hydraulic ram pumps have been large, heavy and unnecessarily complicated.
